My wild guess on the Mac release ... IMHO it's too quiet. It won't be out today or tonight, september 6th.
Next week, september 12, there will be an Apple event where MacOS Sonoma will be released. Will Baldurs Gate 3 be presented there?
So I think we'll all have to wait till the official release of MacOS Sonoma is out.

While I wait for the BG3 release, I play it on the Geforce Now platform. The Steam saved games can be loaded again later on MacOS.
