I have just upgraded and cannot get the the Photoshop plug in to appear.
I am on an M1 Mac Mini running the latest version of Photoshop via the Creative Suite. Having read through some of the threads it would appear that it’s not going to work for me.
I have an M1 MacBook Air which is running Nik Collection. You need to open Photoshop using Rosetta. Do not open Photoshop from Creative Cloud. Hopefully they’ll fix this soon.
