Appalachian State University's IT currently follows the model of supporting the latest released version of MacOS (following an internal testing period) and one version previous. Currently, supported versions include MacOS 10.15 (Catalina), MacOS 10.14 (Mojave) and MacOS 10.13 (High Sierra). MacOS 10.15 (Catalina) is currently in the testing phase.
Beginning in February 2020, ITS will begin notifying users of their available eligibility for MacOS upgrades in an effort to ensure system security. The message you see will depend upon how many versions back from our recommended version of MacOS you are currently running and what your device is eligible to run.
