I played through Act 1 three times on Mac during Early Access. When the full game came out, I couldn't wait, so I got GeForce Now - the online dealio, and it's been amazing. Both on my M1 MacBook Air (at 2560) and on Mac Studio on a 4k monitor at full 4k. You have to pay for the higher tier ($20/mo) for the higher resolutions but honestly it's amazing. I have regular old 100mbit cable internet. I do plug in over ethernet cable if I can but have also played on wifi. It also works with an Xbox game controller and I've even used the AppleTV display sharing to play with controller on big TV (again at 4k). Anyways thought I would share that to my fellow mac users as a way to play if you are really impatient. (I think they delayed again to Friday). Hope this is useful to someone.
