macOS 11 Big Sur - Not Supported

Testing in Progess

With the release of Apple's macOS 11 Big Sur operating system on November 12, 2020, SCS Computing Facilities is currently assessing core software and services for compatibility and future support.

At this time, we do not recommend installing Big Sur in either preview or final form until our testing is complete. Upgrading prematurely may result in potential issues.

To monitor our testing progress visit our  macOS Big Sur Support page for important compatibility and application information regarding this latest release.  You can also find a full list of our operating systems and support status on our operating system support lifecycle page.
