MacBook Pro won’t accept password to unlock after macOS Monterey update

Hi my MacBook Pro just did the MacOS Monterey update last night and since has shut me out. It does not recognise my log in password. I’ve tried restarted, rebooting, changing password etc but nothing seems to be working. I know the password is correct it just will not accept it and it will just restart itself randomly. And when I get the option to change password and try it it doesn’t work. It’s less than a year old.


any help would be much appreciated

had same thing. looked like it didn't complete the installation. i shut down, then restart holding: command + option + P + R altogether holding until 2nd restart. resets PRAM(NVRAM). my computer then went on to restart several more times which yeah was worrisome, however after it completed what it needed to do was working normally again.


hope this helps.

I am having the exact same problem. The problem isn't with with my ability to reset my password, or even knowing what my password is - the problem is that my Mac won't recognize my correct password even after resetting it. The problem commenced immediatey after updating the OS Update and isn't recitified through any of the disk utility options or setting a new password.


Any guidance would be much appreciated as this laptop is currently a paper weight.

Exact same problem as all the users above!


For clarity, I am able to reset the password using Recovery Mode and my Apple ID, but then upon restarting, the MacBook simply will not recognise the new passwords I’m choosing - and it’s not that the system is freezing or timing out, as the password box shakes as though I’ve definitely input the wrong password!


Don't think I’ve got many more options that completely erasing my Mac now, unless we get a more meaningful reply on here.
