Well, 12.3 - I guess it is time to leave Big Sur behind.

Hopefully this is enough releases to have all the bugs squashed…

Monterey completely SCREWS people with 5000 and 6000 series GPUs, halving their performance, both in benchmarks and real world usage (games, blender, etc).

This NEEDS to be made a huge headline on MacRumors, Apple's really dropped the ball on this. Anyone whos got a dGPU should avoid 12.3 like the plague.

wait. I just thought of something, I have a 2017 imac i7 27" 5K. as my backup machine. my main mac is a MacBook pro max 14"

when they first announced this it looked like this imac did not make the cut for Universal control.

Does anyone know if they support more macs now?
Most of these features they’re reserving for M1 Macs because Apple.
