Has it really been that long? Apparently so. Valve originally announced their rebranding of Steam Play with Proton back on August 21st, 2018. Seems like a good time for a quick reflection being halfway to a decade old now with the tech that gave rise to the Steam Deck.
Gaming on Mac is a bit of a new territory. You can install Linux on modern Macs through Asahi Linux, but most games don’t work on it yet since it’s still somewhat experimental.
If you want to stick with MacOS, there’s a sort of Proton for it called Game Porting Toolkit. You may want to look at some benchmarks on it.
