How to Upgrade to Mac OS Sonoma

Part I: Before You Start the Update.

You can update your computer from home or school. Please keep your computer plugged in, and do not turn it off or close the lid during the 1-4 hour update cycle.

  1. Back up files on your computer to Google Drive. 
  2. Restart your computer. (Doing so will ensure you have quit any open apps and saved your work.) 
  3. Plug your computer into power and leave it on. Doing so will ensure your computer stays on during the upgrade.
  4. Please don't close the screen on your computer, shut down, or restart your computer.
  5. It would be best if you planned for the upgrade to take 45 min. to 4 hours to complete.
