The upgrade will take about 1-2 hours to complete. During this time you will not be able to use your Mac. If the install fails at any point, restart your Mac and try to upgrade again from Self Service.

Upgrading at Home

The macOS Monterey installer is about 12 GB. Note if your home Internet plan has a data cap or bandwidth limits it may be difficult to to upgrade.

You will possibly need to free up disk space in order to complete the upgrade. Common places to delete files from include...

  1. Applications. Large unused Applications like iMovie, GarageBand, Keynote, Pages, Numbers, etc. Note: most users do not have permissions to remove Applications themselves. Open a help desk ticket by emailing
  2.  User home folder. Desktop, Documents, Downloads. Delete files or move to Google Drive.
  3. Other application support and cache folders. Primarily ~/Library/Application Support for apps which are no longer installed.

If you have any concerns about being able to upgrade from home or freeing up disk space please open a help desk ticket by emailing

Follow the directions below to complete the upgrade.

Freeing up disk space

One common barrier for installing MacBook updates is a lack of space. This is especially true on older devices. To help with this, we have increased our options in Self Service for uninstalling larger programs. Once an update is completed, you can reinstall these programs.

Uninstallers are available for:

  • Garageband
  • iMovie
  • Microsoft Office Applications (all except Outlook)

If you need assistance freeing up additional disk space please contact the help desk (

3. Search for Monterey in the search bar and select Upgrade to macOS Monterey.

4. On newer model Macs you may be prompted to enter your password. This is a requirement and must be the same password you use to log into your Mac.

5. The macOS Monterey installer will be downloaded. This file is about 12 GB and usually takes between 20-45 minutes to download. If you are on a slower wireless connection it may take longer.

6. If your Mac does not meet the upgrade requirements you will see an error message. Make sure your Mac is plugged into power and has at least 26 GB of disk space free. If you receive an error message multiple times in a row, restart your Mac and try to upgrade again.

7. Once the installer successfully downloads it will prepare your Mac to upgrade and automatically reboot to complete the install process.
