Larian Studios Forums Baldur's Gate III Baldur's Gate III - Technical & Gameplay Problems White screen on iMacPro

I am playing on iMacPro 2017.

Since MacOS 11.1, I can't play in full screen mode. Windowed mode works, but that is annoying.

If I start the game with full screen mode, or change to full screen afterward, with max resolution, it just give me a white screen.

Same here.
MacBook Pro 16" (2019); Big Sur 11.2.2

I can't get past the completely white screen after the launcher.

Spoke too soon - turning off HDR in the launcher lets me start it.

Yes, that is the solution given to me from support.
