Any date announced yet? The longer the wait, the bigger the wave of refunds will be hehe

What exactly was your goal starting this topic ?

Yes GOG is (MUCH) smaller than Steam. And thus slower etc. It is known.

Gaming on Mac, who even does that? hehe

I don't see it. Last I read:
"Baldur’s Gate 3 will release on September 6th on PS5 (September 3rd for owners of the Digital Deluxe Edition). We’re also targeting September 6 for Mac (via Steam, GOG, GeForce NOW) — to be confirmed. Additional platforms TBD."

Have you looked at the store page?

Currently the latest MacOS version on Steam and Gog is EA Patch 9.

If you are in the position where you are threatening a refund, why not just use the game porting toolkit? It's easy af with Whiskey and the performance is excellent. And that line about supporting the mac development with a mac version purchase is irrelevant on GoG, they can't tell which you bought.

You can run the game on mac using wine:
