End of Support for macOS 10.13 High Sierra


macOS High Sierra will no longer be supported by the University managed Macs as of March 31, 2021. If your University Mac is running High Sierra, we encourage you to upgrade your Mac to a newer OS.


Major software products and vendors that the University relies on, including Apple, Microsoft, and CrowdStrike, are no longer supporting or providing updates for any of their products on High Sierra. Due to these changes as well as security and bug considerations, it is important for you to update your Mac to be on a currently supported operating system. To update your Mac, follow the directions below. 

  1. Backup your data, especially any critical work related files.
  2. Close down all programs.
  3. Launch the Self Service app from your Applications folder and login with your University netID and password.
  4. Search for and launch one of the below upgrade options:
    • macOS Mojave was released in September 2018 and is the successor to High Sierra. It is a very stable operating system and will be supported for an additional year. The expected end of support is the end of 2021.
    • macOS Catalina was released in October 2019 and is the successor to Mojave. It is a very stable operating system and should be supported until the end of 2022. Please be aware, Catalina does not run 32-bit applications, so if you have a concern about any older apps installed on your Mac, we recommend you run the Go 64 policy in Self Service to check your Mac for any 32-bit installed applications. 
    • macOS Big Sur was released in November 2020 and is Apple's newest operating system for macOS. Support is expected to last until the end of 2023. University provided software and workflows are supported and compatible with Big Sur, but please be aware it is a recent release and may have some unexpected issues.
  5. Allow the applicable installer to download and install on your Mac. The upgrade may take 45-60 minutes to complete. 
  6. After the upgrade is complete, you may need to update some of the installed apps on your Mac, like Microsoft Office, to their latest versions.
