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 13 Ventura
  • macOS 12 Monterey

Backup Your Data

Before updating your Operating System, it is highly recommended that you backup your data. Please follow Apple’s backup guide using the built-in Time Machine.


Update Your Software Applications

Software Applications also need to be kept current to ensure your security and ability to operate in the enterprise. Apps that should be checked for updates include Microsoft Office, Cisco AnyConnect VPN client, Citrix Workspace, and any other application you rely upon to conduct business. PEAS Self Service in your Applications folder has all current enterprise software available for download.
