macOS Catalina, 64-bit, 32-bit, and related Questions

While all of our 32-bit games will continue to function on macOS Mojave, we’ve decided to remove these games from sale by the end of the day today (6/17/19). After today, the entire library of Aspyr titles on Mac will be 64-bit or will receive a 64-bit update before September. For Steam players, if you stay on Mojave, you will be able to access your 32-bit Aspyr titles purchased on Steam.
