OIT follows Apple's support lifecycle on macOS operating system releases. Apple provides support, including updates and patches, for the most recent macOS version along with the previous two versions. macOS versions older than the current 3 releases are considered out-of-support and must be upgraded to a supported release to maintain a secure security posture.
