Ehh... hold your horses buddy.
While my main gaming machine is my PC, I do sometimes off game on my MacBook Pro when I'm away and it's hardly AS horrible as people make it out to be. It sure is not a powerhouse gaming platform, but for example it's enough to run something like WoW at native resolution at 60FPS with average details and quite a few other titles too.
It certainly is plausible that BG3 will be able to be tuned to run on these machines reasonably well considering it's not some absolutely insane graphics powerhouse there.
