I dutifully upgraded my software (beta) on Feb. 24 when prompted. I could not get the computer to reboot, then after about 5 hours on the phone with, I think, 4 techs, they told me the only solution was to wait for the next update - I could not go backwards to the regular version. So $1,299 later I have a new Mac Mini M4! I have to work, so it was the only solution. What do I win?
