Isn't it odd that Baldur's Gate 3 runs on Steam Deck but any Mac with an M1 or M2 SoC isn't viable?
My son actually ran it on his M1 MacBook Air - not great visuals but it worked. And on release that is how I'd describe the Steam Deck play (can't believe I put in 120 hours with 10-30FPS performance!). But I think for me it just reinforces that Apple really needs to do a lot to truly compete in this space - they have amazing hardware and the Metal framework has possibilities ... but for a little Linux-based handheld to whoop its butt is sad. I will continue to hope for Apple to do some sort of Proton-like layer to interface with Steam.
