This free, open-source tool for playing Windows games on Mac just bit the dust
The popular Whisky compatibility layer will no longer see updates.

There are a handful of ways to play Windows games on Mac, but one of the more popular options over the past few years has been Whisky. Also known as WhiskyWine, it leverages Apple's Game Porting Toolkit (GPTK) and the Wine compatibility layer to make Windows games playable on macOS. Best of all, it's free. Tools like CrossOver offer similar capabilities, but you'll need to spend money upfront. Unfortunately, the solo developer behind Whisky is abandoning the project, as spotted by TechSpot.
