HOWTO: Upgrade Your macOS

It is Mass General Brigham policy to download all current Operating System & software updates for your Mac. Vulnerabilities are discovered frequently in software, and they put your Mac, your data, and the enterprise at risk. To stay protected, ensure that you are running a current, supported Operating System, and that your software applications are up to date. 

To update your Operating System, launch System Preferences > Software Update. Proceed to download and install all available updates. 

Supported Mac Operating Systems

Apple supports their current Operating System and two versions prior. Vendors only release updates for supported Operating Systems, so Mass General Brigham enterprise services like Email, Citrix, and VPN rely upon a Mac that is up to date. Check your Operating System version from the Apple Menu Icon > About This Mac. The supported Apple Operating Systems are:

  • macOS Monterey 12.0 (2021)
  • macOS Big Sur 11.0 (2020)
  • macOS Catalina 10.15 (2019)

Running an Operating System other than those listed above puts you at risk. If you are running an older Operating System, and after performing a backup and determining application needs (see below), you can proceed with the macOS upgrade.
