Do Old Versions of macOS Get Updates?Īpple’s track record suggests that the company will update the latest version of macOS plus the previous two versions. These include iMacs from 2014, the 2013 MacBook Air and MacBook Pro, and 2015’s MacBook. As an example, the 2021 macOS Monterey update drops support for several machines that were compatible with the previous version (Big Sur). This generally happens once the machine is seven or eight years old. At that stage, these machines are potentially “stuck” on the last compatible major release forever. As modern machines become more powerful, there comes a point when older machines simply aren’t up to the task anymore. MacOS is designed first and foremost for Apple’s latest computers. These upgrades happen once per year, normally around October, and they have a new name like Catalina, Mojave, or Big Sur.
