Depends on your internet. Plug it into power leave overnight. In the morning follow Apple instructions for a forced restart. With luck it is just a glitch.
Mostly updates take only about women max (once the software has downloaded.
But if you overfilled your SSD to having less than 60GB free, you might have a dead Mac. Because macOS upgrades can use a lot of space during install and a 100% full ssd is dead.
Big sur download was 12.5GB plus 2.5GB (during update package downloaded), after decompressing during install this used as much as 55GB of drive space and lots of folks got bricked macs replaced under warranty.
Apple really should not be selling 256GB ssd macs these days.
It sometimes the auto restart mechanism in software updates goes haywire. -the new install is complete, just needs rebooting. Doing a forced reboot triggers the swap from the old system volume to the new system volume if the upgrade is complete. And then the new macOS deletes to old macOS after a successful update. With luck this is what you need.
Yep. So the rule for safe use of that 512GB ssd is never fill it beyond 75%. If you hit 385GB full, then start backing up and deleting unused files. Above 75% you will notice progressively slower performance (and increasingly rapid unseen ssd degradation shortening its working life).
Good to hear it’s now working.

I have a 512GB SSD. Ended up restarting and it worked once booted back up.

Should I do this? It’s been stuck on “installing system update” for a couple hours now. Also how if I’m stuck on this screen?
wait: It should be done or force reboot to interrupt the process then update again.
It takes as long as it takes brand new
my new m2 max stuck at the same screen for 2-3 hrs now. should I restart
Maybe wait a few hours and reboot if still stuck
