If you’re running macOS High Sierra 10.13 or earlier versions of macOS, you should upgrade to a newer version of macOS immediately as High Sierra and older versions are no longer supported by Apple. Not only that, but the campus recommended antivirus for Macs is no longer supported on High Sierra which means Macs that are running this older operating system are no longer protected from viruses and other malicious attacks.
In early February, a severe security flaw was discovered in macOS. Apple fixed the vulnerability in Big Sur 11.2.1, Catalina 10.15.7 and Mojave 10.14.6, but did not fix High Sierra and dropped support for that version. Software vendors have quickly followed suit and no longer support products on High Sierra which includes Microsoft Office 365 and Adobe CC 2021.
If you are a customer of OIT’s Dedicated Desktop Support service and would like help or have questions about upgrading your operating system, please submit a request through the Dedicated Desktop Support Service Request Portal. All others are welcome to contact the IT Service Center (firstname.lastname@example.org or 303-735-4357) or schedule an appointment with OIT’s Buff Techs desktop support team for help to upgrade.
OIT’s Software Life Cycle page provides guidance to the campus community on recommended operating systems, productivity applications, web browsers, and email & calendar software. Based on OIT testing, the page provides a useful guide for which software is recommended, near end of life, should be upgraded or is in an early-adoption phase.
