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??) 🙂
