Big Sur updates

Try the following:

#1 - boot into Safe Mode according to Start up your Mac in safe mode - Apple Support.

NOTE: Safe Mode boot can take up to 10 minutes as it's doing the following; 

• Verifies your startup disk and attempts to repair directory issues, if needed

• Loads only required kernel extensions (prevents 3rd party kernel/extensions from loading)

• Prevents Startup Items and Login Items from opening automatically

• Disables user-installed fonts 

• Deletes font caches, kernel cache, and other system cache files

#2 - go to the App Store, search for and download the full Big Sur installer.

#3 - run the installer from the Safe Mode.

I've had better luck goring thru the App store than thru the System/Software Update preference pane.

My macbook pro 2017 after the update to the 11.5.2(20G95) reboot and stuck asking me "an internet connection for an important update for the mac and until is not installed you can't use the mac"

(the password for the connection it's ok..).

i've tried even to reinstall from the safe mode bigsur downloaded from appstore..but he ask me to authorize the disk...(and the password it's ok)

i don't understand ..i never have a problem with the updates....i made a time machine from the safe mode..but it's made from that macos. i really don't know what i need to do...

PLEASE HELP ME!
