My mouse and keyboard are connected via the USB dock function of my monitor.

After the update, I can't even login. Great.

Not that it was working well before. To get the second monitor to even turn on, I had to first power off and then subsequently turn on again the primary monitor.

And that ritual was unique to my M2 Pro Mac mini.

On Windows, or a M1 Pro Macbook, everything just works.

And I'm not the only one with this super annoying external monitor issue. Apple apparently never fixed it. It just sucks.

yea, same thing here. I have the M1 Pro MacBook, connected via usb-c hub. No bugs so far.
