Hello everyone, I have a MacBook Pro, 13", 2020. Since the upgrade my TouchID button didn't unlock my Mac anymore (entering password manually works) and other TouchID activities (App unlock, Apple Pay) didn't work too. In fact, I couldn't even create a new fingerprint. I also couldn't activate the location system, so the app "find my mac" didn't work, for example. BUT THIS IS THE SOLUTION: Please, see Gimmick1973's post! Everything works now! shut down your Mac; press and hold the power button for 10 seconds, then release the button; wait a few seconds, then press the power button to turn on your Mac.
