Major Version Support

We support the current major version of Mac OS X and offer limited support for the two previous OS X versions. Support phases may vary. For the most up-to-date resource on supported operating systems, check our game-specific system requirements pages:

Note: Check Software Update regularly to make sure you are using the most recent update.

Support Update

We announce any changes to our operating system support, including before an operating system enters or leaves its support phase. By providing notification of these support changes, we hope it will ease the transition from version to version of the Mac operating system.
