macOS 13 Ventura has been released. As a result, macOS 10.15 Catalina computers must be updated in order to meet DFCI security requirements. The supported macOS is the current version or the two prior macOses. This means you must be running macOS 11 Big Sur at a minimum by October 24 or risk being out of compliance with security requirements. Please stay ahead of the curve.
