Catalina is definitely not Linux.

And I am not sure what you meant by obtuse error messages? My steam clearly marks the games that don't run under Catalina (which as a few false positive actually -- since .NET game still runs despite being mark as not compatible).

I didn't screenshot the error messages, but I'm a developer and they were at that level: incomprehensible to end users. So I figured it out but only because I was savvy. Now my girls want PCs. Usch!

I don't know what you are talking about because in my stream it is written there in a yellow text next to Play button that 'this games does not support Catalina'.

That must be new. A while back the only way was to buy and try.
