They state ”beginning of September”, so pretty good actually. Particularly for those of us with both a PC and a Mac, since we can just seamlessly keep playing the campaign that we started on PC. (Both versions included in the base price)It is a separate team from "Larian proper" doing the port. So I assume QC and bug fixes are going to take a bit longer.
If they follow the Patch cycle (how long it takes macOS to get the latest patch) it will be 5 weeks, which puts it at launching the same time the PlayStation version does.
I’m perfectly fine with that. I hope that they at some point include Metal upscaling as well, as it would be a bit better quality than FSR1.
It’s a good game in its genre. Really good.
