The company has also stated that older titles that receive updates or patches may stop working on systems running Snow Leopard altogether.
Aspyr also stated in the post that 8% of its existing audience is on Mac OS X 10.6, down from 16% in January. Recently, the company has published games such as Bioshock Infinite and Borderlands 2 on Apple's platform. According to a report from yesterday, Apple is targeting a late October launch for OS X Mavericks.This means all future releases of Aspyr games, as well as any patches and updates for existing Aspyr games, will no longer be supported on Mac OS X 10.6 (Snow Leopard); in some instances, older titles that receive updates or patches may cease to work on OS X 10.6. To continue to play the latest Mac games, we recommend upgrading your computer or operating system to the latest version of OS X.
