Operating System Upgrades


GeekHampton technicians follow a standard procedure when upgrading operating systems.


  1. Evaluate Computer. CRITICAL: Before starting, please look over the computer and make sure that the upgrade that is being requested is appropriate. If you think the customer should not do the upgrade or that they should add RAM, please discuss this with the customer before proceeding.

  2. Backup. If the “Problem Description” field of the “SRO” indicates that the customer does not have a Time Machine backup, a backup of the customer’s home folders must be done before advancing. CRITICAL: Do not perform operating system upgrades on any computer that has not been backed up.

  3. Update current OS: Computer’s OS and all firmware must be up-to-date before upgrade. If not, update the OS accordingly.

  4. Run “Disk Utility” if applicable. (Note: as of macOS 10.11, El Capitan, “Disk Utility” has been changed and the OS has built in automation of “Disk Permission” repair)

    • Run disk utility to repair “Disk Permissions” and “Verify” the hard disk.

    • If the hard drive integrity cannot be verified, attempt to repair the drive with file system check.

    • The file system check must indicate that the drive has been repaired before proceeding with the system upgrade. If no errors were found, proceed.

  5. Upgrade the OS to the next version of the operating system. 

  6. If the operating system needs to be purchased through the App Store, refer to the information in the “Problem Description” field of the SRO and use the Apple ID and password provided by the customer.

  7. Install the latest updates via Software Update

  8. Complete the “Repair Completion Checklist." See “General Workflow” policy for copy of checklist.

  9. Call the customer to notify them that the computer is ready for pick up.
