Elder Scrolls Online. I was happily playing it after moving to Playstation a couple years ago, but my IRL friends sucked me back in. Now I'm all setup, and 2 of the 4 have stopped playing. Grrr. Maybe I'll just go back to PS.

EDIT: And before anyone suggests it, yes, I've tried it many times on macOS. On my $4000 Intel Mac with a Vega 20 GPU, it pauses so often to load textures, it's almost a slide show. It runs BETTER on a Mac WITHOUT a GPU. Even my buddy with his new M2 Studio only gets 30 FPS at medium settings, while my $700 PC gets 60 on high. If ZOS would somehow address this WIDE disparity, I'd GLADLY give up the PC, but they have officially given up on Mac.
