I used to be able to lock my MacBook Air with my TouchID. Now I can't.

If you hold down the TID button, it will lock your MBA. You need to use one of your fingerprinted fingers.

Thanks for participating in the Apple Support Communities, JohnGaylor59.

We understand that you're no longer able to lock your Mac with Touch ID, so we'd like to share some resources with you. Start by making sure you're running the latest version of macOS Monterey (12.2.1): Get the latest software updates from Apple. If it's already updated or if updating doesn't help, follow the steps outlined in this article, including adding another fingerprint: If Touch ID isn't working on your Mac.

If the issue persists, reset the SMC if your Mac has an Intel processor: How to reset the SMC of your Mac.

Best regards.

The Touch ID in Sys Preferences says nothing about using it to LOCK anything. And I'm running 12.2.1

There doesn't seem to be any way to use TID to LOCK anything. There's no box to do that in System Preferences.

Do you use same finger for unlocking?Did you try it by separate finger ?

If you hold down the TouchID button, the computer will lock. It doesn't have to be an enrolled fingerprint. You can use any finger.
