Supported Versions of macOS

Apple is only supporting macOS 10.11 or later. Apple stopped providing security updates for macOS 10.8 and earlier versions with the release of macOS 10.11 (El Capitan) in 2015.

Using a version of macOS that is no longer supported puts the security of your comptuer, your personal accounts, and the information stored on your computer at risk. Additionally, if your OS version is 10.10 or earlier, then you will be unable to run the current version of the Cisco AnyConnect VPN software that allows you to access restricted University business systems securely.
