This is a community forum, which is where conversations take place based around the problem, not necessarily the user. I have the same problem, so I'm joining the conversation. You're suggesting that a community forum only answers questions to a single user, if that user was the one asking the question.
There are no real answers on this page, so what makes you think starting another question, and talking about the same problem, would generate any answers there? Typically, on almost all forums I know, asking the same question elsewhere gets a load of answers telling you to go look at the previous user who asked the same question, which is what I'm doing.
I gave you context, a black screen showing a progress bar that has not moved for 24 hours, perhaps I missed the bit where this started by clicking the Update notification, but with a page title of Monterey Update stuck, I thought that was the topic of the conversation.
Things tried so far...
Waiting
Restarting router and computer, progress bar back to 1/3, me back to waiting
Disconnecting computer to reset SMC
Trying to log into Safe Mode, holding Shift key, computer just reboots in a loop
Trying to log into HD (Option key), progress bar to 2/3 then computer shuts down.
Trying to log into Update Installer, progress bar to 2/3 then computer reboots, progress bar back to 1/3, me back to waiting
Normal restart, goes into Update Installer (I assume), progress bar back to 1/3, me back to waiting.
So after all that, one finds the user (me) staring at a Monterey update that is stuck.
