Most of my Steam collection won't run on my Mac. It's not (entirely) my fault.
I will be the first to admit that my collection is mostly old indie games, all of which work fine on Windows. Less so on the Mac. Apple stopped supporting 32-bit games back in 2019 when it released macOS Catalina. A good chunk of my Steam library has a "No" symbol next to it because of that restriction. And next year it will get even worse: macOS will drop support for running Intel Mac applications, which could leave even more games unplayable (though Apple claims that certain older games will keep working).
