Apple macOS support

Apple does not publish the support lifecycle for its operating systems. New versions of macOS typically launch during the third quarter of the year.

CTS will follow Apple's model of supporting the three most recent macOS versions and discontinue support for any versions outside of this window at the beginning of each new year.
