When Should You “Ignore Ownership” on an External Drive?

Under the hood, macOS relies on Unix, which is a multi-user operating system. That’s why a Mac can host multiple users who, as long as they don’t know each other’s passwords, cannot see each other’s files. To maintain each user’s privacy, macOS relies on permissions that specify who can do what with any given file or folder. For the most part, permissions work how they’re supposed to, letting you work with all your files and keep any other users on the Mac out of your stuff.

Where things can get tricky is with external drives. In some situations, permissions can prevent you from accessing files written to an external drive on one Mac from another Mac. That happens because the first admin user account created on a Mac is given the UniqueID of 501, regardless of its name. (Because, Unix.) If you create additional accounts, they get UniqueIDs of 502, 503, and so on. Again, the names are irrelevant; all that matters is the UniqueID.

If you write files to an external drive while logged into the 501 admin account on one Mac but then try to access those files from an account with any other UniqueID on that Mac or any other, macOS won’t let you. No 503 account, for instance, can access a 501 account’s files.

There are tweaky Unix solutions to this problem, but Apple realized this would be an issue from the early days of Mac OS X and provided a single-click solution: the “Ignore ownership on this volume” checkbox. When selected, it tells macOS to pay no attention to permissions for all the files and folders on a drive, regardless of what that might mean.

To access this setting, select the drive in the Finder, choose File > Get Info, and expand the Sharing & Permissions section at the bottom. Before you can select the checkbox, click the lock icon and enter your admin password when prompted.

There are three scenarios where enabling “Ignore ownership on this volume” is helpful:

• Multi-user access: Imagine that you share a Mac with family members or colleagues. You want to keep your email and text message conversations private but need to share numerous other large files stored on an external drive. (For just a few files, use the Shared folder alongside your user folders.) By enabling “Ignore ownership,” you can be certain that all users of the Mac can do whatever they need to with those files.

• Access from multiple Macs: Suppose you have a portable SSD containing video files you want to display from any Mac. Perhaps they’re canned business presentations or home videos. Since you cannot know what the UniqueID of the current account on any given Mac will be, selecting “Ignore ownership” will ensure that you can open your videos regardless.

• Juggling user accounts: Although it’s a bad idea to do this willy-nilly, some people regularly create and delete accounts for their own use. Since all the accounts are used by a single person, they don’t think about permissions as an issue, but macOS does unless they select “Ignore ownership.”

In general, when using an external drive to move files between accounts, people, or Macs, select “Ignore ownership” to prevent pesky permissions problems.

But that doesn’t mean you should turn on “Ignore ownership” in every situation. There are some situations where enabling the setting would be inappropriate because it’s essential to preserve permissions:

• Boot drives: macOS itself relies on specific permissions and won’t even show the checkbox for boot drives. If you’re planning to install macOS on an external drive and use it to boot a Mac (Apple provides instructions), make sure not to select “Ignore ownership” before starting.

• Time Machine drives: Time Machine cares deeply about maintaining correct permissions, so you should not enable “Ignore ownership” on a drive that you plan to use with Time Machine. After Time Machine starts backing up to a drive, the “Ignore ownership” checkbox disappears.

• Bootable duplicates and other backups: Similarly, if you’re using Carbon Copy Cloner or SuperDuper to create a bootable duplicate of your boot drive, “Ignore ownership” must be unchecked. Retrospect also warns users to turn off “Ignore ownership” on backup and restore drives to ensure that permis-sions are preserved. Other backup apps likely have similar requirements.

One last thought. If you run into permissions-related problems reading files from an external drive, it’s worth enabling “Ignore ownership” to see if that resolves your issues. If it doesn’t, or if the problems keep cropping up in different contexts, contact us.

Prep Your Tech for Travel

Long ago, to get ready for a trip, we’d mostly make sure we had our plane tickets, books and magazines to read, and a snack. Prepping for travel in today’s tech-heavy world comes with a new set of tasks, most of which shouldn’t be left to the last minute.

Identify Devices, Chargers, and Cables to Bring

Resist the temptation to bring every piece of tech you have. Do you really need your iPad and MacBook Air if you’re not planning to work on vacation? Is a point-and-shoot camera worthwhile if you take most of your photos with your iPhone?

Once you’ve selected your preferred devices, think about charging. At a minimum, you’ll need chargers for all your devices every night. You may not find many power outlets or be able to access them easily, so a compact power strip is often helpful, especially if it comes with USB Type-A and USB-C ports. Multi-device wireless chargers can also reduce the number of wall chargers and cables. If you’re traveling abroad, a power adapter is essential—you can find units that support multiple devices.

Make sure to pack the right charging cables for your devices. Increasingly, that means USB-C cables, but remember that most public charging ports in airplanes and hotels will still be USB Type A, so bring an appropriate cable or adapter for such situations.

Portable battery packs can be a lifesaver, such as for late-night transit navigation after you’ve run down your iPhone’s battery taking photos and videos during the day. Unless the battery pack has integrated cables, ensure that you carry the right cables with you every day.

Prep Updates, Backups, Apps, and Entertainment

We always encourage staying up to date on operating system updates for security reasons. It’s especially important to update before leaving on a trip where you may be in less secure situations. Don’t leave those updates for the night before you leave! The device you’re updating won’t be usable while the update installs, which may be stressful, and in the rare case where something goes wrong, you’ll need extra time to recover. Always update your devices and apps at least a few days before leaving.

It’s also important to make backups before you leave. It’s easy for a device to be damaged, lost, or stolen while you’re traveling, and a backup is essential for recovery. For Macs, make sure your Time Machine and other local backups are current. For iPhones and iPads, iCloud backups are best while traveling because you can continue to back up while away, and if you have to replace a lost iPhone on the road, you can restore from your iCloud backup wherever you are.

You may find a new set of apps helpful on your trip, and some may be essential for checking in for flights, going through customs, and more. If you’re flying, configure your airline’s app to know about your flight and add your boarding passes to Apple’s Wallet app. Paper copies of travel documents are worthwhile in the event of your iPhone being damaged, lost, or stolen. Travel guides for specific locations and itinerary planners like TripIt may also be helpful, though you can also track your travel and itinerary in Notes, which you can share with fellow travelers. An app like Flighty can help you track your flights and better react to delays.

Even if you prefer Apple Maps or Google Maps, having the other available when you travel is worth it. One or the other may work better in certain places or with certain types of navigation, like city transit. Connectivity isn’t always guaranteed while traveling, so download maps ahead of time in both Apple Maps and Google Maps.

If you’re heading to a country where you don’t speak the language, make sure you can quickly access Apple’s Translate app. Also get Google Translate so you can find out which you prefer. Both translate text you enter, text you focus on with the camera, and the contents of conversations.

It’s always best to load enough ebooks, podcasts, and videos on your iPhone or iPad so you don’t run out of something to do during downtime when there’s no connectivity. With ebooks, if you’re not already using Libby to access your public library, give it a try. It’s easy to download episodes in most podcast apps. And nearly all streaming apps like Amazon Prime Video, Apple TV+, Disney+, Hulu, and Netflix allow downloading. That said, leave plenty of free space for taking photos and videos on your travels.

Investigate Cellular Connectivity Options

Cellular Internet access isn’t usually an issue when you travel within your home country as long as you don’t have a data cap. But when traveling internationally, you need to plan for how you’ll get cell service. Your carrier may have an international roaming plan, but those are often massively overpriced. Instead, look to an international roaming provider such as Airalo, Airhub, and Nomad.

Factors to consider when choosing an international roaming provider include the provider’s network coverage at your destination, how much data you’ll need, whether you’ll also need voice and SMS support, the duration of your trip, and whether your iPhone supports eSIM technology.

Protect Tech You Leave Home

Don’t forget the tech you’re leaving behind. Shut down your Macs and unplug anything not protected by an uninterruptible power supply. That way, a power surge or lightning strike won’t hurt anything.

Unplug your Time Machine and other local backup drives and hide them in a secure location—you don’t want to lose both your Mac and your backups in the event of a burglary.

If you use HomeKit, set up automations to turn lights on and off to make it seem like you’re home. Make sure you can remotely access home monitoring systems like security cameras. Consider a motion sensor like the Kini to report on doors or items that shouldn’t move (unauthorized access) or should move regularly (a scheduled pet sitter).

We know that can sound like a lot, but you want to avoid the aggravation of arriving at your destination only to discover that you forgot a necessary cable or can’t get Internet access. An excellent way to remember everything is to use an app like Packing Pro, which lets you develop (and reuse) lists of items and tasks.

Have a great trip!

It’s Usually OK to Share Full-Size Images in Email and Messages

In the early days of the Internet, when most people connected via slow modems, saving bandwidth was a big deal. You could watch images load on Web pages, and you’d have to wait to download a large email attachment before the rest of your email would appear. For most people, in most situations, bandwidth isn’t nearly as big of a deal anymore. The average Internet download speed in the US is nearly 250 megabits per second, such that most Web pages load instantly, email just appears, and we think nothing of having multiple video streams playing at once.

All that’s by way of saying that you don’t have to shrink images that you share in email or Messages in most cases, and doing so can cause problems for recipients. The most common issues people run into are images being too small or fuzzy to see, not matching the dimensions needed for a website, or being too low quality to save for posterity.

There are exceptions. Smaller or lower quality images may make sense when sending or receiving in rural areas with slow Internet connections, places with no Wi-Fi and tenuous cell service, and remote locations with only satellite Internet. In those cases, you’ll either realize that messages are taking a long time to send or hear from the other party that it’s a problem. But, most of the time, it’s best to send actual size images, so let’s look at how you ensure that.

Sending Actual Size Images in Email

How do you ensure you’re not sending downsized images in email? In Mail on Apple’s devices, the details vary slightly depending on which device you are using, but in each case, you want to use the Actual Size option. Neither Gmail nor Outlook suffers from this problem. Here’s what you need to know for each of these email clients:

• Mail on the Mac: When you drop an image into a Mail message, an Image Size menu specifies the size at which it will be sent. Small resizes the longest side to 320 pixels, Medium to 640, and Large to 1280. Actual Size sends the original image, which is what you want. The Image Size menu remembers its setting, so if you send one image in a smaller size, you probably want to reset it to Actual Size for the next one. If you attach multiple images in a single message, they’ll all be resized similarly.

• Mail on the iPad: On the iPad, when you add an image to a message, you’ll see a note in the header information that says something like “Images: 2.9 MB.” Tap anywhere in the header to reveal extra header fields, including an Image Size line with options for the different sizes. Small and Medium work as on the Mac, resizing the longest side to 320 and 640 pixels, and Actual Size sends the original, which is generally what you want. However, Large resizes the image to half the size of the original if appropriate or leaves it alone if not. Multiple images will be resized to the selected size.

• Mail on the iPhone: Because of the iPhone’s smaller screen size, Mail on the iPhone asks how to resize the image(s) after you tap the send button. The results are the same as on the iPad, described above.

• Gmail on the Web: You don’t need to do anything when sending images in Gmail to prevent them from being resized. Although Gmail lets you visibly resize an image with handles and offers Small, Best Fit, and Original options when you click, none of them change the file size or resolution of the image being sent. Only some receiving email apps (including Gmail and Outlook, but not Mail) will display the sent size. Regardless of the visible size, opening an attached image reveals that it’s the original. Note that Gmail has a 25 MB limit on attachments and may refuse to send a message with more than that or may resize images to make them fit. If you need to send an image at a particular size using Gmail, resize it before attaching—see below for a tip on how to do that.

• Outlook on the Mac: You can visibly resize images sent in Outlook on the Mac, but doing so affects only the displayed size, not the file size or resolution of the attached image. Email clients receiving an Outlook-resized image may do so at the sent size, but opening it reveals that it’s the original image. If you need to send an image at a smaller size, resize it before sending—read below for help.

Avoiding Lower-Quality Images in Messages

Although it may seem confusing, keeping images from being resized in email is pretty straightforward. Ensuring that you send full-quality images in Messages is trickier because there are multiple variables in play:

• Turn off Low Quality Image Mode: Make sure you turn off Settings > Messages > Low Quality Image Mode on the iPhone and iPad. (The Mac has no comparable setting.) This mode downsizes images sent via iMessage (blue bubble conversations), making them smaller and lower quality. Only turn it on if it’s paramount that you save bandwidth due to a slow connection or data cap.

• Avoid sending via SMS/MMS: There’s no need for Low Quality Image Mode for messages sent via SMS (green bubble conversations) because the MMS technology used to send images for SMS conversations has size limits that vary by carrier, usually between 500 KB and 3.5 MB. Messages automatically resizes and compresses images to fit within carrier limits. You have no control over this process, which is likely to be unpredictable. If you need to send someone a full-quality image, use email instead of SMS. Happily, in iOS 18, Messages will support the RCS standard that allows full-quality images.

• Prefer high-speed connections: Although Apple doesn’t document anything along these lines, some suggest that Messages may reduce image size or quality when using slow networks. If you (or your recipient) experience issues while using weak cellular connectivity, try again when connected to the Internet via high-speed Wi-Fi.

Bonus Tip: How to Resize an Image Manually

Let’s flip the problem around. Say you use Gmail or Outlook and need to send an image with specific dimensions or a smaller file size than the original. How do you do that easily? Preview! That’s right, Apple’s Preview works well for resizing images and shrinking file sizes.

To resize an image you have open in Preview, choose Tools > Adjust Size and enter the desired width or height into the appropriate field. As long as Scale Proportionally is selected, Preview will automatically set the other dimension to resize the image proportionally. You can choose other units, but pixels is generally best. Preview even reports on the resulting size at the bottom. After you click OK, save the image.

What if you want to reduce an image’s file size without changing its dimensions? With the image open in Preview, choose File > Export, choose JPEG from the Format menu, and move the Quality slider to the left to increase the JPEG compression. Preview reports on the new file size each time you move the slider. You’ll want to export a few tests to determine the best combination of file size and quality.

Generally speaking, changing an image’s dimensions is a better way to reduce file size than increasing compression.

But really, in most cases, just send the original image.

Two Techniques for Improving Google Chrome Security

Although most Mac users rely on Apple’s Safari for Web browsing, plenty of people prefer Google Chrome for its cross-platform compatibility, massive collection of extensions, and tight integration with the Google ecosystem. Chrome is by far the most popular browser in the world, with about 65% of the market, compared to Safari’s 18%. Still others opt for alternative browsers based on the same open-source Chromium engine, such as Arc, Brave, Microsoft Edge, Opera, and Vivaldi.

Unfortunately, Chrome’s dominance makes it a target for attackers in two ways. First, attackers may attempt to find vulnerabilities that would let them steal data or compromise credentials. Second, although Google reviews extensions submitted to the Chrome Web Store, researchers have discovered malicious extensions with millions of downloads. To keep your copy of Chrome secure, we recommend two things: relaunch the browser regularly and be careful with extensions.

Relaunch Chrome to Install Updates

Google Chrome and all the other Chromium-based browsers update themselves automatically. Sort of. While the browser is running, it downloads the latest update but doesn’t install it until you quit and relaunch. Since both macOS and most apps are highly reliable, many people go weeks or even months without relaunching, leaving Chrome vulnerable to recent security exploits. You can check if you’re running the latest version or need to install an update by choosing Chrome > About Google Chrome. (Some extensions, like 1Password, even refuse to run when an update is required.)

In other words, it’s important that you quit and relaunch Chrome and any other Chromium browsers regularly—we recommend a weekly schedule to match Google’s schedule for security updates. There’s no need to worry about losing your open tabs as long as you set Chrome to “Continue where you left off” in Chrome > Settings > On Startup. All the Chromium-based browsers have a similar setting. (While we’re on the topic, remember that it’s also a good idea to restart your Mac occasionally!)

There is one exception among the alternative browsers: Arc. Its developers have figured out how to download and install updates automatically. The feature is still being rolled out to all users, but when enabled, it installs updates when the Mac wakes from sleep rather than forcing the user to quit and relaunch.

Be Careful with Chrome Extensions

Chrome extensions can be both a blessing and a curse. There are vastly more Chrome extensions than Safari extensions, so Chrome and the Chromium browsers enjoy added features that Safari lacks. On the downside, in 2023, researchers discovered dozens of malicious extensions with tens of millions of combined downloads. Google has removed all of them, but many had been on the Chrome Web Store for 6 months or more.

There are over 100,000 extensions in the Chrome Web Store, so while malicious extensions are real, most extensions are legitimate. But if Google can miss them for months or years, how can you reduce the chances of installing something evil? Here’s what we do:

• Reduce the number of extensions you install: The fewer extensions you install, the less likely one is to be malicious or cause other problems. Regularly uninstall any extensions you don’t use from Window > Extensions (the location may vary slightly in the Chromium browsers).

• Only install from the Chrome Web Store: Stick to extensions that have at least gone through Google’s reviews for the Chrome Web Store and avoid direct downloads for extensions.

• Read reviews before installing: Although reviews are no guarantee, if you see people complaining about unusual behavior, that may be a clue that the extension is doing something sketchy.

• Evaluate extension metadata: In general, avoid extensions that aren’t used by many people, that don’t have many reviews, or that aren’t updated frequently. Those aren’t guaranteed signals of a malicious extension but may be a hint to be cautious.

• Review permissions before installing: When you click the Add to Chrome button in the Chrome Web Store, a prompt explains what permissions will be granted to the extension. If they seem unnecessarily broad, cancel the installation.

Don’t stress too much about this. Maintaining good Chrome security comes down to relaunching the browser once a week and being careful about which extensions you use—it’s easy.

Choosing the Best Mac for a College-Bound Student in 2024

Is your child heading off to college soon? They’ve undoubtedly been using a computer throughout high school, though now is a good time to look at getting them a new one, especially if theirs is old or unreliable, is shared with other family members, or was a school loaner. If you haven’t been keeping up with Apple’s Mac lineup, you might be unsure which model is the best choice.

First, check with the college before buying. Although this is less common than in the past, some college departments have specific requirements based on the software students use in their classes. Generally, these revolve around processor type, amount of RAM, and storage space. Current Macs should meet or exceed all those requirements. More problematic is if the college requires a Windows machine; if that’s the case, see if the requirement is based on specific Windows-only software needs or is just a general desire on the part of the IT staff to maintain a homogeneous support environment. Second, see if the college provides access to educational pricing—most will—to save a few hundred dollars off the prices listed below. Regardless, Apple often has a Back to School offer.

Aim for a laptop over a desktop Mac. Students lead nomadic lives and need to get work done in multiple places on campus, so having to head back to the dorm to use an iMac or Mac mini will be limiting. Plus, they often need to work during breaks, so they need a Mac that’s easy to bring home. A student accustomed to taking notes on an iPad with a keyboard and Apple Pencil might be able to use that in conjunction with a desktop Mac, but most students should get laptops.

In the past, deciding which model was best for a given student was more challenging, but Apple’s move to the speedy and power-efficient M-series chips makes the decision easier. We see three primary scenarios:

• Most students: Buy Apple’s MacBook Air, Apple’s lightest and least expensive laptop. Within the MacBook Air line, you have four choices. The least expensive is the 13-inch M1 MacBook Air from 2020, which costs $699 exclusively from Walmart. Get it only if budget is paramount. The three remaining choices begin with the 13-inch M2 MacBook Air from 2022, which Apple has kept in the lineup at $999. However, the longest-lasting choice is either the 13-inch or 15-inch M3 MacBook Air introduced in March 2024. The 13-inch model boasts a 13.6-inch screen, faster performance, 24 GB memory ceiling, and up to 2 TB of storage, starting at $1099. Those who want a larger screen should look at the 15-inch M3 MacBook Air, which starts at $1299 and is otherwise nearly identical.

• Better specs: If performance is more important than price—especially if your student will be working with processor-intensive tasks like video editing—look to the 14-inch MacBook Pro. It features a powerful M3, M3 Pro, or M3 Max chip, and the M3 Pro and M3 Max models can be configured with much more memory. Although its 14.2-inch screen is physically a little smaller than that of the 15-inch MacBook Air, it has a somewhat higher resolution. Its price starts at $1599 but goes up quickly with the M3 Pro and M3 Max chips. (There’s also a 16-inch MacBook Pro, which comes only in M3 Pro and M3 Max configurations and is more than most students need.)

• Windows compatibility: The only downside of the transition to Apple silicon is that it’s more challenging to run Windows using virtualization software like Parallels Desktop (half-price for students) or VMware Fusion (free for personal use). If Windows compatibility is a bonus but not essential, either of those with the Arm version of Windows 11 should work for most apps. However, if Windows compatibility is paramount, your choices are a used Intel-based MacBook Pro or—much as we hate to say it—a PC laptop that runs Windows natively.

Regardless of which laptop you decide on, you’ll have to pick a processor, amount of memory, and storage capacity:

• Processor: With the 13-inch M1 MacBook Air, you’re limited to the M1 chip with an 8-core CPU and 7-core GPU. The 13-inch M2 and M3 MacBook Air models always have an 8-core CPU, but you can pay $100 to upgrade from an 8-core GPU to a 10-core GPU. The 15-inch M3 MacBook Air always comes with a 10-core GPU. The performance difference isn’t likely noticeable with everyday apps, but for $100, it might be worth upgrading, just in case. The 14-inch MacBook Pro has two M3 Pro options and one M3 Max option; choose between them by weighing likely performance needs against increased costs.

• Memory: The 13-inch M1 MacBook Air only comes with 8 GB, which is acceptable for most college students. The M2 and M3 MacBook Air models and the M3 models of the 14-inch MacBook Pro offer 16 GB and 24 GB options. We usually recommend 16 GB to reduce the chance that memory becomes a performance-limiting factor, although 24 GB could be helpful in higher-performance situations. With the 14-inch MacBook Pro with M3 Pro or M3 Max, the amount of memory changes with the chip. The M3 Pro comes with 18 GB standard, but you can opt for 36 GB. With the M3 Max, 36 GB is standard, with options to upgrade to 48, 64, 96, or 128 GB.

• Storage: For all the MacBook Air models, 256 GB is the lowest storage level, and you can upgrade to 2 TB. The 14-inch MacBook Pro starts at 512 GB and offers upgrades up to a whopping 8 TB. Choose the amount of storage based on two considerations: budget (storage gets expensive fast) and anticipated usage (audio and especially video production can consume a lot of space, as can very large numbers of photos, but most other uses don’t). Remember that it’s easy to connect an external Thunderbolt SSD or hard drive to offload large files that don’t always have to be available. Large files can also be kept in cloud-based storage.

For most students, the best choice for a Mac likely to last across four years of college would be the 13-inch or 15-inch M3 MacBook Air with a 10-core GPU, 16 GB of memory, and 512 GB of storage. Although the 15-inch size has a larger screen, it’s also heavier and takes up more space in a backpack, so consider portability when making your final choice. Be sure to budget for AppleCare+, too; it’s almost guaranteed that some mishap will befall a student laptop, and AppleCare+ covers up to two incidents of accidental damage every year.

We recommend having conversations with your child to find out what they think they’ll need—and be sure to compare against the college’s recommendations—but if you have any questions after that, feel free to contact us.

At WWDC, Apple Unveils Apple Intelligence and Previews New OS Features

Apple’s Worldwide Developer Conference keynote was a lightning-fast (even in the full 1:44-long video—or try the 3-minute recap) look at what Apple is bringing to the software side of the Apple experience in the next year. Although some past keynotes have introduced hardware like new Macs and the Vision Pro, this year’s keynote stuck to new operating system features before previewing a suite of AI features collected under the umbrella term “Apple Intelligence.”

Apple previewed a boatload of new features and listed even more on its website. We’ll focus on those we think will make the biggest splash in your Apple experience, but we recommend that you scroll through Apple’s pages for each operating system to see more of what’s coming. Those are linked below, along with basic hardware requirements so you can see if your devices will be eligible to upgrade (not all features will be available on all devices):

• macOS 15 Sequoia: iMac Pro from 2017, MacBook Pro and Mac mini from 2018 and later, iMac and Mac Pro from 2019 and later, MacBook Air from 2020 and later, and Mac Studio from 2022 and later

• iOS 18: Second-generation iPhone SE, iPhone XR, and later (same as iOS 17)

• iPadOS 18: Seventh-generation iPad and later, fifth-generation iPad mini and later, third-generation iPad Air and later (including M2 models), first-generation 11-inch iPad Pro and later, and third-generation 12.9-inch iPad Pro and later, and all M4 iPad Pro models

• watchOS 11: Second-generation Apple Watch SE, Apple Watch Series 6 and later, and Apple Watch Ultra and later

• tvOS 18: Apple TV HD (with fewer features), Apple TV 4K

• visionOS 2: All Vision Pro headsets

Here are a handful of new features we think Apple users will find most interesting. Then we’ll look at Apple Intelligence.

Personalize Your iPhone and iPad Home Screen

iOS 18 and iPadOS 18 introduce significantly enhanced Home Screen customization options aimed at letting your creativity shine through. You can leave blank spaces between icons and arrange icons and widgets however you like. Additionally, you can change the size of icons and widgets and apply color tints.

Tile Windows Automatically in Sequoia

macOS has long had a subtle window alignment effect that makes it easy to line up windows, but in macOS 15 Sequoia, when you drag a window to the side of the screen, macOS suggests a tiled position on your desktop, intelligently sizing it for the window’s content. Window tiling makes it easy to put windows side-by-side and fill the screen without wasting space. Keyboard jockeys will appreciate new keyboard shortcuts for window tiling as well. (If you don’t want to wait for Sequoia, numerous utilities offer similar features now, including Amethyst, BetterTouchTool, Magnet, Moom, Rectangle, and Yabai.)

Notes and Phone Gain Audio Recording and Transcription

If you find yourself wanting to revisit what was said in a lecture, appointment, or phone call, a pair of upcoming features can boost your recall. The Notes app on all platforms will record audio and create live transcriptions, allowing you to pay attention during a talk rather than furiously taking notes. Plus, the Phone app in iOS 18 will let you record and transcribe a live call—when you start recording, participants are automatically notified so everyone knows it’s happening.

Mirror Your iPhone on Your Mac

If you frequently pull out your iPhone while working on your Mac, you’ll appreciate Sequoia's new iPhone mirroring feature. It lets you use your Mac’s pointing device and keyboard to interact with all your iPhone apps in a window on your Mac while the iPhone remains locked or in StandBy. Audio from the iPhone plays through your Mac, and you can share data between devices with drag and drop. A related Continuity feature displays iPhone notifications on your Mac—when mirroring your iPhone, clicking those notifications opens the associated iPhone app.

Passwords Breaks Free of Settings

At long last, Apple has given us a dedicated Passwords app in Sequoia, iOS 18, iPadOS 18, and visionOS 2. The company’s password management features have become quite good over the past few years, but they are awkward to access in Settings on the iPhone and iPad and System Settings on the Mac. We don’t anticipate significant feature changes beyond the addition of categories, but the Passwords app should make managing your logins even easier. Passwords still won’t fully match up to the likes of 1Password, but you won’t go wrong with Apple’s built-in solution. Remember that if you use a Web browser other than Safari, you’ll need the iCloud Passwords extension we’ve mentioned previously. You can also share your passwords with a Windows PC using iCloud for Windows.

Five More Welcome Features

For more reasons to upgrade once these new operating systems are out and stable, consider the following additional features:

• Customize Control Center: iOS 18 and iPadOS 18 feature a thoroughly revamped Control Center, accessible with a continuous swipe down on the Home Screen. You can create custom groups of controls—some from third-party apps—with resizing and mixing options.

• iPad Calculator app and Math Notes: Not only does the iPad finally get a Calculator app, but it also introduces Math Notes. You handwrite an equation with an Apple Pencil, and when you write an equals sign, Calculator solves the equation. Math Notes works with keyboards, too, and you can also find it in the Notes app.

• Lock and hide iPhone apps: New privacy features in iOS 18 and iPadOS 18 let you lock apps with Face ID or Touch ID so the friend who’s scrolling through your vacation photos can’t also read your journal. You can also move apps to a hidden folder in the App Library that can’t be opened without biometric authentication.

• More tapbacks: In Messages, when you want to use a tapback to acknowledge a message without typing out a reply, you’ll be able to use any emoji or sticker, or a new AI-powered Genmoji.

• Vitals app collects overnight data: When you wear your Apple Watch to sleep, a new Vitals app in watchOS 11 collects and displays your overnight health metrics on your wrist, including heart rate, respiratory rate, temperature, blood oxygen, and sleep duration. It might help you rest up to fight off that cold that’s going around.

Apple usually releases its new operating systems in September or October; we’ll write more about them as we get closer. Generally speaking, it’s OK to upgrade to everything but macOS shortly after release; with macOS, we recommend caution to ensure your existing apps and workflows won’t be impacted.

Apple Intelligence

Apple devoted a large chunk of the keynote to introducing Apple Intelligence, a collection of AI-powered features coming to the Apple ecosystem over the next year. These features will enable your iPhone, iPad, and Mac to understand language and create both text and images, plus take actions aimed at simplifying your interactions with apps. What sets Apple Intelligence apart from AI efforts from other companies is its focus on—and understanding of—your personal context. Apple Intelligence will know about your contacts, schedule, email, messages, photos, and much more.

The most significant use of Apple Intelligence will come with Siri, which will let us speak more naturally and understand what we mean if we make mistakes. We’ve trained ourselves to say only things Siri is likely to be able to handle, but that won’t be necessary when Siri gains Apple Intelligence capabilities. You’ll be able to search for photos of your child holding a fishing rod, for instance, or ask Siri to find something when you can’t remember if it was in Mail or Messages. Siri will also gain context awareness, so you can ask what the weather will be like at the beach tomorrow, and if the response is good enough, have it schedule a trip there. Siri will even know a lot more about your Apple devices and can help you use them. For the most part, though, Siri won’t have global knowledge. If Siri can’t answer your query directly, it will offer to send it to ChatGPT for free.

Apple Intelligence also includes writing tools, but unlike ChatGPT, it’s not aimed at creating text from scratch. Instead, it can rewrite text you’ve written to help you fine-tune the wording or adjust the tone to be more appropriate. It can also proofread text, helping you with grammar, word choice, and sentence structure (if you need this now, check out Grammarly). Even when Apple Intelligence does create text, such as the Smart Reply feature coming to Mail, it asks you questions to guide its response.

Text summarization powered by Apple Intelligence shows up repeatedly. In Notes, you’ll be able to summarize a transcription. If you save a long article to Safari’s Reader, it can provide a table of contents and summary. In Mail, instead of the first few sentences appearing in the message list, you’ll get a short summary. Apple Intelligence can even prioritize and summarize notifications.

Unsurprisingly, Apple Intelligence lets you create and edit images, but it’s a far cry from the AI artbots that let you create photo-realistic images. Instead, Apple Intelligence lets you create custom emoji, called Genmoji, which let you express yourself graphically in ways that standard emoji can’t support. Image Playground lets you create images for inclusion in conversations and documents, but it limits you to three styles: Sketch, Illustration, and Paint. Apple doesn’t want anyone making deepfakes with Apple Intelligence. A new Image Wand feature in Notes even turns your rough sketches into polished images.

Apple took great pains to emphasize the privacy aspects of Apple Intelligence. Most Apple Intelligence tasks will take place entirely on your device, hence the need for powerful Apple silicon chips with their Neural Engines and Secure Enclaves. Some tasks require more processing power; to handle those, Apple has developed a highly secure system called Private Cloud Compute. It relies on Apple silicon servers, transfers only the data necessary to the task, and stores nothing.

Apple Intelligence features will start arriving in the fall and continue to roll out in feature-release updates over the next 6–8 months. They will run only on the iPhone 15 Pro, iPhone 15 Pro Max, and iPads and Macs with M1 or later chips. Intel-based Macs and less-powerful iPads and iPhones need not apply. Apple Intelligence will also require Siri and the device language to be set to US English in the early releases, with other languages to follow.

Overall, Apple appears to have put a great deal of thought and effort into integrating AI into the Apple experience in focused, helpful ways that offer new capabilities while preserving user privacy. We won’t know how well these features will work until they ship, but we look forward to seeing how they can improve interactions with our Apple devices.

Sorry, Apple Isn’t Going to Update the 27-inch iMac with Apple Silicon

Are you a 27-inch iMac owner wondering when Apple will release a new model with speedy Apple silicon? We hate to be the bearer of bad news, but the answer seems to be an unequivocal “Never.” Late last year, Apple confirmed to The Verge that it would not be making an Apple silicon version of the 27-inch iMac. Technically, that leaves open the possibility of a 32-inch iMac, for instance, but that feels like wishful thinking given the $5000 cost of Apple’s 32-inch Pro Display XDR. How did we get here, and where should 27-inch iMac owners look next?

Apple introduced the 27-inch iMac with 5K Retina display in 2014 and updated it several times before discontinuing it in 2022. It was hugely popular due to its large, gorgeous screen and a price that made the guts of the Mac seem cheap when paired with such a nice screen. An 8-year run isn’t bad, but once Apple introduced the powerful Mac Studio and the 27-inch Studio Display (also a 5K Retina display), the company felt there was no room for the 27-inch iMac in the lineup.

Apple isn’t necessarily wrong. One of the reasons 27-inch iMac owners are so attached to their Macs is that they can’t upgrade the computer and keep using that lovely screen, which remains one of the best available. Target Display Mode (which lets you use some much older iMacs as an external display for another Mac) never supported that model of iMac, and although the $80 Luna Display dongle does let you use a 27-inch iMac as a screen for another Mac, its tradeoffs may be hard to accept.

In the new world order, an Apple silicon Mac paired with a Studio Display provides a fast, capable Mac you can swap for a newer one when necessary and an extremely nice display you can use across multiple Macs. It’s not uncommon for an external display to last a decade or more, whereas many businesses upgrade their Macs every 3 to 5 years. A Studio Display could easily outlast two or three Macs.

“But, but, but,” we can hear you spluttering, “what about the 24-inch iMac with Apple silicon?” It may seem odd for Apple to drop the 27-inch model but keep a smaller iMac around. The reason is that the 24-inch iMac is meant to be a low-cost Mac that doesn’t skimp on display quality. It has a 4.5K Retina display that’s just a little smaller than the 27-inch iMac’s 5K Retina display while matching its quality. (Those numbers refer to the number of horizontal pixels on the screen—4,480 or 5,120—although the actual resolutions nearly everyone uses are half that to get crisp text at a readable size.) A Mac mini paired with an inexpensive external display would be cheaper than a 24-inch iMac, but you would have trouble getting a comparably good display for so little. The 24-inch iMac is perfect for a receptionist’s desk or a family’s kitchen computer, and its M3 chip will seriously outperform the Intel chips in the now-discontinued 27-inch iMac.

So, let’s assume you’ve been holding onto your 27-inch iMac, but it’s finally time to move on. The calculus of what to buy has changed due to the excellent performance of the Apple silicon Macs, even on the low end, and the existence of the Studio Display. Here’s what we recommend for different needs:

• You’re on a very limited budget: Buy a 24-inch iMac. The screen isn’t quite as large, but the price/performance ratio is hard to beat for such a nice screen. The lowest-end model has fewer USB ports, which might be annoying.

• You want a basic desktop Mac with a Retina screen: Choose between a Mac mini paired with a Studio Display or a 24-inch iMac, which is comparable to the low-end Mac mini. For higher performance needs, go for the Mac mini with an M2 Pro.

• You want portability, too: The Studio Display works well with a MacBook Air (13-inch or 15-inch) for a budget solution or a MacBook Pro (14-inch or 16-inch) for a high-performance option. Using two screens also increases productivity.

• You’re willing to pay more for performance: Things get interesting here because you can use a Studio Display with a Mac mini with M2 Pro, a Mac Studio with M2 Max, or a MacBook Pro with either M3 Pro or M3 Max. The MacBook Pro options are the most expensive but offer portability and a second screen.

• You want the ultimate performance: Pair a Studio Display with a Mac Studio or a Mac Pro, both of which come with the M2 Ultra. The choice comes down to expandability: the Mac Pro offers PCIe slots and more ports.

Right now, the M-series chips are a little confusing. The original M1 is available only in an inexpensive 13-inch MacBook Air model sold exclusively through Walmart. The previous MacBook Air (13-inch only), Mac mini, Mac Studio, and Mac Pro all use variants of the M2, whereas the newer MacBook Air and MacBook Pro models sport M3 variants. Until recently, we expected Apple to standardize the rest of the line on the M3, but then the iPad Pro came out with an M4 because of yield issues with the M3 fabrication process.

It now seems probable that some models will skip the M3 entirely in favor of the M4, but don’t get too caught up in the latest and greatest. There’s more performance to be gained in the Pro, Max, and Ultra versions of the chips than in the next generation, so for now, the M2 Ultra remains the fastest chip for most processor-intensive tasks.

Regardless of what Mac and display combination best meets your needs, you’ll enjoy vastly better performance than was available with the 27-inch iMac, and the Studio Display is every inch as good a monitor. And maybe you can sell your 27-inch iMac on eBay.

How to Make Productive Use of Generative AI Chatbots and Artbots

Artificial intelligence dominates the tech news these days, but it’s hard to separate the hype from the reality. Every large company seems to have some major AI initiative in the works. Even Apple, which tends to stick to its own path, has started to tout features previously described as relying on “machine learning” as being “AI.” If you can get past the hype, AI has plenty of good uses now. 

Despite Apple’s recent relabeling of features as using AI, when most people think about AI, they’re thinking of “generative AI” systems like OpenAI’s ChatGPT chatbot or Adobe’s Firefly artbot. These systems generate impressively good text and images from scratch based on user prompts. Ask ChatGPT to write an excuse for your sick kid, and you’ll get fluid, correct English. With Firefly, describe an image—“silhouettes of male and female runners with bright colors and black background”—and you’ll get images that match pretty well.

How do they accomplish this magic? Chatbots use statistical models to predict the next word based on training datasets that contain hundreds of billions of words—think autocomplete on radioactive steroids. Artbots work a little differently, but they also use statistical models to create images based on having been trained to identify numerous images.

Enough background. How can you make the most of today’s leading chatbots (ChatGPT, Claude, Copilot, Gemini, Meta AI, Pi, and Le Chat Mistral) and artbots (Adobe Firefly, Microsoft’s Copilot Designer, NightCafe, Meta AI, and Midjourney)?

Identify Good Uses of Generative AI

It’s essential to recognize that the effectiveness of generative AI for a particular task is highly individualized. What works for one person may not work for another due to varying skill levels, requirements, and preferences. With that in mind, here are three ways to evaluate tasks that might be a good fit for generative AI.

• Skill levels: The less skillful or knowledgeable you are about a subject, the happier you’ll be with generative AI’s results. You can think of an AI chatbot as a C+ student—its work will get a passing grade, but it won’t fool an expert. But we’re all happy to do or receive C+ work in many parts of our lives—no one is above average in everything.

• Requirements: Are you looking for something definitive—precisely what you have in mind—or would you be happy with an open-ended set of results? AI chatbots and artbots generate statistically likely results, so if you’re not caught up in things being just right, you’ll probably like what you get. Don’t expect them to read your mind, however.

• Preferences: It’s best to think of an AI chatbot as an assistant, because you must be willing to go back and forth with it. And that means you have to be willing to work with an assistant who is dumber than they seem, entirely reactive, unpredictable, and inconsistent. (On the plus side, chatbots are also tireless, imperturbable, incredibly well-read, and non-judgemental.)

To sum up, the best tasks for generative AI are those where you know little or aren’t particularly skillful, don’t have specific expectations about what you’ll get, and are willing to interact with a potentially annoying helper.

Get Better Results from Generative AI

These recommendations will help you get better responses from AI chatbots:

• Set the stage with detail and expectations: Unlike Web searches, chatbots work best when provided with more than essential keywords. Instead, tell the chatbot a little about yourself, provide background about the topic, and lay out your expectations. ChatGPT even lets you provide instructions to apply to all your chats. Additional detail helps the chatbot’s statistical model better predict what you want.

• Iterate repeatedly and push harder: You don’t have to provide all that detail up front. Chatbots retain context—they know what has been said in the chat—so after your initial prompt, you can and should keep pushing the chatbot to refine and improve its answer. Don’t be shy to ask, “What’s missing from this?” or “How could this be improved?” While it’s always best to be polite, there’s no harm in asking a chatbot to do better. Pretend you’re a coach or therapist and keep asking probing questions.

Remember, unlike a search engine, where each search stands alone, working with an AI chatbot is a conversation. Right now, that’s less true of AI artbots, but we’re moving in that direction.

Good Uses for Generative AI

AI has innumerable possible uses, limited mostly by your imagination. Here are a few that have worked well for us:

• Brainstorming: Have you ever needed to come up with a name for a program, product, or service and found your mind utterly blank? Or maybe you’re writing and can’t put your finger on precisely the word you want? Ask an AI chatbot! With a little direction, they’re great at coming up with a bunch of possible names or words. You may not get exactly what you want, but the chatbot’s suggestions will help you think in new directions.

• Coding: An AI chatbot won’t turn you into a professional programmer, but it can help you write a small AppleScript to automate a task like adding sequentially numbered calendar events to every Monday for the rest of the year. Chatbots are also good at helping you use powerful but complex Unix tools for reformatting text like sed, awk, and grep. But perhaps our favorite real-world use is getting help with devilishly complicated spreadsheet formulas that do lookups as part of their calculations.

• Talk to documents: Some AI chatbots (and services like ChatPDF) enable you to have conversations with long documents. That sounds weird, but it’s much easier to ask a few questions about how a hundred-page report affects your business, for instance, than to slog through the entire thing. Such systems provide page references to support their answers, so you can (and should) verify what you’re told.

• Drafting difficult email: Some email messages are hard—no one likes having to reprimand an employee, express condolences to a business associate, or announce layoffs. But such messages are essentially genres—if you’ve seen one corporate merger announcement, you’ve seen them all. If you seed your prompt with plenty of appropriate details, an AI chatbot can generate a credible first draft that you can tweak to improve accuracy and make it sound like you instead of an overeager college student. Never send an AI-generated email without taking an edit pass.

• Evaluating ideas: It’s always a good idea to talk through ideas and decisions, and conversations with AI chatbots can help you think about them. Should you ask for a raise or try for a promotion? What are the pros and cons of moving to a new location? Does it make more sense to rent or buy? An advantage of AI chatbots is that you can tell them to respond like a particular type of professional, such as a lawyer, financial advisor, or life coach. Of course, all chatbot responses are just statistically probable, so they won’t compete with those from actual professionals, but they’re a good start.

AI-Powered Searching

Finally, let’s look at AI-powered search engines like Perplexity and Arc Search (on the iPhone), and increasingly prominent AI-generated summaries in Google, Bing, and Brave Search. They blur the distinction between search engines and chatbots. Search engines focus on providing answers to questions, either link to or summarize their sources, and include the most recent information. In contrast, chatbots focus on conversation, generate answers from scratch, and always have some date after which their knowledge stops.

When might an AI-powered search engine be more effective than a traditional search engine’s list of links? Try one in situations like these:

• Searches for easy but non-obvious answers: If you want to know who held the mile world record before Hicham El Guerrouj, for instance, an AI search engine will just tell you, rather than make you read a Wikipedia page about the world record progression. It could even tell you who has come the closest to his world record in the last decade, which would be difficult to determine otherwise.

• Searches for answers to idle questions: If you don’t want to spend a long time reading source materials and don’t care much about the answer, an AI-powered summary will be efficient.

• Searches that require assembling information from multiple sources: Imagine that you want to know how many people live in New York City, Boston, and Chicago. With a traditional search engine, you’d need to find each city’s population independently (or a list of major US city populations) and add them manually. An AI-powered search engine could find them all and add them for you.

• Searches where you don’t quite know what you’re looking for: When you’re starting to explore a topic, an AI-powered search engine can suggest additional searches as you home in on aspects of the topic that especially interest you.

Google’s recent addition of AI-driven summaries quickly drew mockery for suggesting the addition of glue to pizza and encouraging the ingesting of rocks. But remember, humans say incorrect things all the time, often intentionally. In fact, both of those examples were triggered by jokes and could have come up in traditional searches as well, but in contexts that were clearly silly.

Regardless of whether information comes from an AI chatbot, an AI-powered search engine, a Facebook post, or the woman next to you on a plane, you have to discern whether it’s likely to be right. AI can be helpful in many ways, but it won’t do your thinking for you.
