Supported macOS Operating Systems

Information Technology requires a minimum of Monterey 12 to ensure that College computers are running a version of macOS that is fully supported.

Get connected
Installing a new version of macOS will take some time, so make sure you are on stable Internet connection. If you are upgrading a laptop, plug it into a power outlet. If you are off campus and do not have a fast/stable Internet connection or have a data cap, we do not recommending upgrading at this time.
Begin Installation with System Preferences

If your System Preferences doesn't include Software Update, you can use this link to find out how to upgrade macOS, and use the Updates tab of the App Store app to get app updates.
- Click Update Now or Upgrade Now:
- Update Now installs the latest updates for the currently installed version, such as an update from macOS Ventura 13.5 to macOS Ventura 13.6.
- Upgrade Now installs a major new version with a new name, such as macOS Monterey. Software Update shows only upgrades that are compatible with your Mac.
When Software Update says that your Mac is up to date, then macOS and all of the apps it installs are up to date, including Safari, Messages, Mail, Music, Photos, FaceTime, and Calendar.
Begin Installation with Self Service

Allow installation to complete
Once installation has started, do not put your Mac to sleep or close the lid. Your Mac might restart, show a progress bar or show a blank screen several times as it installs macOS and firmware updates.
