Whisky is a tool that uses Apple's Game Porting Toolkit to allow Mac users to play Windows games on their devices. It provides a hands-off setup experience and native UI, making it easy for users to play games like Baldur's Gate 3 and Cyberpunk 2077. However, the project is no longer maintained, and users are advised to buy CrossOver instead. Whisky relies on Rosetta 2 to translate x86 binaries to ARM binaries, allowing x86 games to run on macOS.
