If you’re using an M-series Mac, download the Windows Steam installer and Whisky. Install Steam through Whisky then simply install games through Steam as normal.

There’s a bit of a learning curve, but /r/MacGaming on Reddit is a useful resource.

There are some that simply won’t work because the hardware won’t run them (Red Dead 2 is the most disappointing one for me), but have a play and see what works.
