macOS Catalina (10.15) Support Status

Support Pending

With the release of Apple's macOS 10.15 Catalina operating system on October 7, 2019, SCS Computing Facilities is currently assessing core software and services for compatibility and future support.

At this time, we do not recommend installing Catalina in either beta or final form until our testing is complete. Upgrading prematurely may result in a potential loss of data and performance as a result of incompatible applications.
