I have the beta installed on my M1 Mac Mini and thus far, only one app crashes when I try to open it —- 1Password. Other than that, it’s been quite stable.
I’ve finally found the time to install the latest beta of macOS Monterey. It’s actually installing while watching the Cowboys vs Cardinals NFL Pre-Season football game…..
Well.. With this beta, I can't get external monitors to work, at all…
Edit 2021-09-30 03:21 UTC: At least iPadOS' SideCar feature still works, so it's a minor mitigation. Still a sub-par experience in my opinion. I have not tested AirPlay.
