Oh trust me, I understand the disappointment, being a Mac user as well. I bought the Early Access version back when the PC and Mac versions would release on August 31st. So when it was announced that the Mac version would be indefinitely delayed, I started a paid GeForce Now account, to make sure I could play tomorrow. NVIDIA also announced that BG3 would be available on their service a few hours after launch. And with the Cross-Save feature, you will be able to continue your adventure once the game is available on Mac. No mod support though, but that is something I can live without for the time being.
