There is no support for Photoshop 2021 on Apple M1 Macs... Very disappoining.
Also worth noting that Option+ (a beta software...) seems the only way to make the mouse (MX Master 3) barely work on my computer (2021 16 MBP, M1 Max) as Options does not work at all. And to conclude of course, after more than a year, no Apple silicon version of the app is available yet...
