SteamOS for Apple Macs is finally here: AAA PC games get tested on MacBook Pro
(www.notebookcheck.net)
I've just installed it on my own M2 Air (16gb/512). So far it's cool to be able to run SteamOS as a Linux VM, but the one game I've tried (so far) - The Talos Principle - just crashed Steam.
My testing continues...
