CTS Recommendations for macOS Big Sur (11.0)

Last updated: Nov. 12, 2020

Apple released its newest operating system, macOS Big Sur (11.0), on Nov. 12, 2020. Anyone using an iMac or MacBook can upgrade to macOS Big Sur for free through the App Store.

Recommended actions

At this time, CTS does not recommend upgrading to macOS Big Sur on University-managed or personally-owned Mac devices. Some applications and software used at the University, such as ExamSoft, is not yet supported on macOS Big Sur.

University-managed Mac devices

MacOS Big Sur is currently in testing and not yet supported on University-managed devices. CTS currently supports macOS Catalina (10.15) on University-managed Mac devices. More information about supported operating systems and software on Apple devices is available on our software webpage.

If you believe you need to upgrade to macOS Big Sur, please contact the IT Service Desk at 412.396.4357 (HELP), help@duq.edu or duq.edu/chat.

Personally-owned Mac devices

Before upgrading to macOS Big Sur on a personally-owned Mac device, CTS recommends adopting a "wait and see" approach. When a new operating system is first released, bugs and compatibility issues are often discovered. To avoid potential technical issues, use an earlier supported version of macOS, such as macOS Catalina, until these bugs and compatibility issues are identified and fixed.

CTS also recommends backing up important files and data to an external drive prior to performing any major operating system upgrade. Doing so ensures your data is preserved in case the upgrade does not complete successfully.
