Touch ID Not Working after Monterey Installed

Turning the keyboard off worked for me/. Thank you.

#2, rebooting the keyboard's Bluetooth, worked for me - thanks!

Since installing Monterey, my fingerprint fails more often than not. I've deleted the fingerprint and added it again in System Preferences I've done the SMC reset thing. Still doesn't work, most of the time. It seems like Apple needs to fix something.

It's intermittent for me. And today (for the first time) the Magic Trackpad also disconnected from my iMac (m1) and would only work if plugged in with the lightning cable. But if I plugged it in, then the keyboard stopped working (completely). So I had to go back and forth plugging each one in, then restarted the machine and now both work again (for now....). What a mess.

Same to my Macbook Pro M1 and latest Monterey. The touch ID seem not working all the time, it works rarely. I have removed the fingers and then add again but can not resolved the problem. Even when I set up the finger, I put my finger on and then it took a long time to recognize my finger (after 4-5 times re-tried I think). Some people talk about reset CMC but I think Mac M1 can't.

This just started happening after I updated to Monterey 12.1 a few days ago. It also will not let me add a new fingerprint. I am stumped.

Try to check the touch id settings.

Good luck

Hey, there!

I've been experiencing the same issue.

I tried all the steps many times with no result.

Then deleted my saved fingerprint but then Touch ID just wouldn't remember my new print.

I'm using MacBook Pro 2020.

I have also experienced this issue.

Prior to installing Monterey, I merely had to rest my fingerprint on the Touch ID key on my keyboard (M1 iMac), now I have to fully suppress the key, and it doesn't work every (most) times. It absolutely DOES NOT work by finger placement anymore.

I also lost the use of my Touch ID and Bluetooth mouse (vertical scroll stopped working first, then all of it) directly after the Monterey install. (which took longer than most installs) For the Touch ID, at first it worked when I depressed the button, then I tried to add another finger's print, now it doesn't work at all. For the mouse, at first, when I turned my mouse off and then back on it worked again, but then it failed again and now won't even pair. (I charged it, turned it on and off several times.) My mac, keyboard, and mouse are brand new. Mahalo in advance for figuring a solution!

About my suggestion that "resetting the SMC on M1 Macs..." might be a fix - I just read that M1 chips provide the same functions internally and - there is no SMC to reset! So... nevermind.

If you're having the Touch ID failures on your Intel-based mac, the SMC reset seems to sort this out.

I'm not sure what it means to reboot the keyboard's bluetooth. or turn the keyboard off and back on. Does the key board have a separate bluetooth from the rest of the laptop or what???

Also, I am not able to add a new fingerprint. In the past, when the touch ID stopped working because of a cut on my finger, I was able to add a new fingerprint.

I have the same problem. I've re entered my finger prints, even adding a different finger. Touch will not work! The Touch Bar is one of the reasons I bought this computer. My computer is out of warranty or I'd send it back. Please tell Apple to fix this.

I have an M-! 2020 Mac Book Air. An article I read on the Apple Support site states that Touch ID should work after logging in with password after not having logged in for 48 hours. This has not been true for me as I have to create a new fingerprint after 48 hors or even less. This happened before, but much worse since Monterey, as you stated. I'll try the SMS reset- thank you!
