Hi trying to update to Monterey 12.5.1 but get as "Authentication is disabled" after putting in my password on a MacBook pro.

Any ideas?

Did you try download form a SafeBoot How to use safe mode on your Mac - Apple Support

and compare your results.

If no resolve you can —

Try starting the update using the command line, this will bypass the secure token/owner check from the Software Update pref pane

from the Terminal.app copy and paste:

sudo softwareupdate -i -a -R

-i Install

-a All appropriate updates

-R Automatically restart (or shut down) if required to complete installation)
