a very incomplete list of games that work on macOS 10.15+, but Steam will tell you are incompatible:
ARK: Survival Evolved
BattleBlock Theater
Goat Simulator
Lethal League
Geometry Dash
Melody's Escape
A Hat in Time (outdated)
Garry's Mod (branch)
if you have a Mac, it's worth going through your "incompatible" games in your Steam library and seeing which ones work and which ones don't! gaming on Mac really isn't as bad as Valve want you to think
