Touch ID not unlocking Mac but working otherwise.

Touch ID will NOT unlock my MacBook Air M1 (Tahoe 26.3) but DOES work to autofill passwords, Apple Pay, buy from App Store etc. Have tried the usual fixes (delete/re-add fingerprints, reset touch id to unlock Mac, tried booting in Safe Mode, etc.) Thinking it is an OS issue (seems to have arrived with Tahoe 26.3. Any suggestions ??

MacBook Air 13″, macOS 26.3

!!! SOLVED !!! Thank you leroy douglas.


After reading the thread I found a reply which talked about entering different "sessions" and I figured out that was meant was different user accounts.


BACKGROUND - For security reasons I have two accounts on my MacBook Air M1, one with Administrator privilege and one with just User privilege. I normally log into the User account, and when I updated to 26.3 it was from this account. Apparently I should have done so from the Administrator account.


SOLUTION - I logged out of User Account and logged into the Administrator Account. There was a slight delay as the Welcome to Tahoe screens appeared (apparently Tahoe 26.0 had been loaded but not actually installed in the Administrator account) and when I went to settings there were no fingerprints installed. I installed a fingerprint and enabled Touch ID for all functions. I logged out of Administrator account and logged into User Account (using password). I then locked screen and now Touch ID WORKS to unlock !!!.
