After upgrade to Sonoma Touch ID stopped working to unlock by single touch

I had the same issue with Touch ID not working after upgrading to Sonoma. I contacted Apple support and went through a few items but ended up with switching the keyboard off and back on. It fixed the problem.

I had a chat with Apple support, and they asked me to run diagnostics. When I tried that, I got "There may be an issue with the Touch ID sensor" with the codes BMT003, BMT004, and BMT005. It seems like I have a hardware issue.

Can anyone who is having the same Touch ID issue try the diagnostics and share your results?

Use Apple Diagnostics to test your Mac - Apple Support (IN)

As mentioned already in the thread:

• Open Settings and select Touch ID
• Turn off the keyboard
• Plug it in directly
• Turn on the keyboard

Worked for me.

Puh-leeze... I've tried everything with my M2 MacBook Air... Touch ID is not working for many things.

Please, take this seriously, INVESTIGATE, give a fix for this.

How exactly do you expect us to do that if we cannot replicate the issue.

I would think you would have to provide us with many more details, but I’m not sure what to look for.

Your problem is not the same as what is being discussed in this post.

You are essentially hijacking this thread with your own problem.

There are a few posts that do describe what may be your problem, or you can start your own post so that this one doesn't get off track fixing a different problem.

No issues on M1 / M2 Computers I own and operate running Sonoma 14.0

There is a Pending 14.1 still in Beta.

Though & generally if the Touch ID is not working in Ventura 13.6 or Sonoma 14.0., unless there is iBridge update in 14.1 - this could be a Hardware Issue with your specific Computer

The issue is that logging in after inactivity isn't working after just touching the fingerprint key. Another key had to be pressed for showing up the regular password prompt window. Then the system unlocks with touching the fingerprint key (no password entry is needed).

I think I got that message on the first page. That's why I suggest to all the "Me Too's" with a different problem they look somewhere else for the solution to their problem.

I can't replicate your problem on a M2 MacBook Pro.

I'm not sure what happens on my M1 Mini with Magic TouchID keyboard. I've got to turn on the TV with a remote, then I likely just hit the keyboard to wake the Mac. I get problems on that entering a password after sleeping overnight. I have to plug in the cable.

I am having the same issue, I have a 2020 Macbbok Pro M1, 8GB running Sonoma 14.0

The touch ID function works once logged in and opens passwords and websites but if I log out of my user account and try to log back in or after a restart trying to use the touch it says " Your password is required to enable TouchID" but it IS enabled and working normally once logged in.

Any ideas?

Please fix.

Normal. It happens after a certain amount of time of being logged out or something. I don’t have a firm grass on the timing. You must periodically login with a password to reenable touch ID.

Sorry to correct you but it happens every time. Either after just logging out or after restarting. It's the same thing, and I had a second Mac come in later in the day with the same issue but it was running Ventura.

Does it happen if you don't log out and just go to the Lock Screen?

I never log out and only have to enter a password after a few days of using Touch ID to unlock.

Same issue with me. I have an M2 MacBook Air and a Mac Mini and both are exhibiting the same issue after upgrading. At login it fails to recognise and fingerprints and I have to revert to a password. I have deleted all fingerprints and started again - no issues with the setup, it just continually fails at login.

I was having this problem ( al ot of others are too)

I have a macair with M2 chip. I shut it down "forcefully" I guess its called? And when it turned back on suddenly the Touch ID problem I had was solved and the spotlight issue.

I don't know if this might help anyone else. It can't hurt to try

Here is a link of how to do this

and for anyone with m1 or m2 chip

I noticed the Touch ID stopped working this afternoon. I am on MacBook Air M1 2020 with Sonoma 14.0.

I got an extra power adapter so I could work with the laptop somewhere else without moving the original charger.

I unplugged the laptop and the Touch ID started working again. I plugged the power cable and it stopped working.

I unplugged it and the Touch ID works without issues.

Just in case this might be of help to anyone.

Update - both my Mac mini and Air are still misbehaving - today I've deleted all the fingerprints and started again. They work for a short while then they just randomly stop working. Really annoying, might have to rebuild both machines to an earlier reliable version. Also noticed bluetooth connection to my Apple Keyboard, trackpad and mouse can be really slow - linked somehow?
