Monterey Install
Tried to install Monterey and now our iMac is “stuck”. Black screen with the Apple logo says “less than a minute remaining” and that minute has lasted for 1 hour and 14 minutes. Help!
Please be patient and wait until the morning, if it is still at one minute when you get up (I'm assuming it is late where you are) then shut it down in the morning. Then unplug it for about 30 minutes, plug it back in and hold down the power button for about 15 seconds.
Sorry you don't find that helpful but you are being impatient.
