The Game Porting Toolkit (GPTK), derived from Wine and released in beta, translates Windows application programming interface (API) calls to equivalent macOS APIs, allowing developers to run unmodified versions of their x86 Windows DirectX games on macOS.

Mac users have been able to use the Game Porting Toolkit to run a number of DirectX 12 games; tech news outlets have compared the tool to Valve Corporation's Proton compatibility layer for Linux.

[15][16] A DigitalFoundry review of the first beta of Game Porting Toolkit found it "impressive", with few graphical glitches and full support for console controllers instead of the keyboard, though they found that frame rates were around half of what they would be on Windows, and that many games were not supported.

[19][20] YouTuber Snazzy Labs issued similar criticisms,[21] which journalist John Siracusa agreed with.

[26] By using patch tools such as OpenCore Legacy Patcher, macOS Sonoma can be unofficially installed on earlier models that are officially unsupported.
