Touch ID slowly fails after Tahoe Upgrade

[litmag01]

After upgrading to OS26 (Tahoe) Touch ID stopped working on M2 MBAir. Deleting the saved fingerprint in settings and re-adding, it works for a while, then only sporadically, and then not at all. Rinse and repeat.

I found a this in Apple Discussions and is my problem exactly (with the exception of the processor). The fingerprint sensor worked all day without issue immediately prior to upgrading to Tahoe from Sequia.


Kinda just want to see who else has this issue. I hope this is addressed in MacOS 26.3.

During the 26.1 version it was prompting me for my password every other time I opened my screen (your password is required for touch id) when it's supposed to be every 48 hours (IIRC). As of 26.2 it seems to have been fixed (and now it's letting me use TouchID without password for a week now?)

I have this exact same issue on my MBP which is still running Sequoia 15.7

Each time I redo the fingerprints I think it is solved, but then the sensing slowly gets more unreliable until it completely stops working.

I'm starting to believe that there must be something wrong with my fingers (fingerprint derangement syndrome??) 🙂

Same, total failure of sensor since upgrading M2 Air to Tahoe. Have it on personal and work laptops. No solution found yet reboot/safe mode/delete print. Apparently Apple are aware. I've found Tahoe really buggy and slow generally.

YES!! After I rescanned my fingerprint twice, I realized this thing just doesn't work anymore. I have had this MBP M1 since 2021 and never had this problem up until Tahoe. I was about to post the same question myself sometime soon.

My Air has gone back to requiring a "password to enable Touch ID" EVERY time again after I wake it from sleep since the most recent update. It was working before, but now the sensor is no longer available for login. It still works for enabling Apple Pay or saved passwords.

It's not failing to read my print, it's just outright refusing with "Your password is required for touch ID" no matter how much time has passed since I closed the lid, be it 5 minutes later or a day later. It used to only require it every 48 hours.
