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

I believe I was able to resolve this following a recommendation I found in another forum. My Touch ID settings were also disabled, and could not use it for anything. I was able to get them re-enabled by the following ( I have an iMac M1 - my Macbook continued to work after Sonoma installation so I don't know if these will be the same for you):

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

At this point the settings were enabled. I tested that they were in fact usable, then unplugged the keyboard and they continued to work.

Good luck

I am having the same problem, touchID does not work anymore. I deleted my fingerprints and now I cannot re-enrolled them. I have clean the fingerprint and fingers but nothing works. my MacBook Air M1 is like new!

Everything used to work until I upgrade to Sonoma.

Apple Please HELP!

This is clearly an issue to be addressed by Apple. My M1 Mac worked fine with touch ID since purchase. As soon as I installed Sonoma it stopped working. I deleted the finger prints as suggested elsewhere and now I can't even add a fingerprint. Runs the process and eventually shows "Touch ID enrollment was interrupted." and requests to start again. Never succeeds. Keep hoping Apple will provide a fix. Sonoma provided nothing I needed, would revert to previous version to restore touch ID if I could.

M2, Sonoma 14.0, exact same thing occurring. I've deleted my saved touch ID fingerprint, re-added 2 fingerprints. Still occurs.

I also reviewed the 'Apple Document' Phillips recommended, and yeah... I know all that stuff, and I'm sure OP does as well.

Please, take this seriously, INVESTIGATE, give a fix for this. One of the reasons I purchased my silly expensive computer is for touch ID, which now is non-existent.

I would love for this to work if someone can post a screen shot of where to "turn off" the internal keyboard......

what helped for me:

1. switch keyboard off
2. plugin in the keyboard to the mac
3. switch keyboard on
4. unplug keyboard from the mac

voila. fingerprint does work again. ;-)

Mac2018, sonoma 14.2 . Same issue, touch id still not working, can not add fingerprint

Same thing is happening on my 24-in, M1, 2021 iMac.

Sonoma 14.0.

Updated and noticed touch ID wasn't enabled. But the toggle switches are all disabled without a way to enable again. I changed my local password, deleted my fingerprint and now the button to add a fingerprint is non-responsive as well.

If I plug in my wireless touch ID keyboard and click add fingerprint it at least opens and tries to initiate, but then errors out with this.

Occasionally a combo of plugging and unplugging and plugging the keyboard back in allows me to see the activated toggles again, but I can't add a fingerprint still.

Mildly annoyed at this unpredictable, and buggy behavior. Happy to try more to investigate.

**** We updated our Macs to Sonoma 14.0 and now when we touch our finger to the fingerprint key, it doesn't work.

In my case, I have several accounts on my Macbook Air with an M1 chip. When I try to use my fingerprint to log into an account, it switches the account and requests I use my fingerprint or password to sign in. No matter how many times I go back to the account I am trying to log into, when I attempt to use my fingerprint, it switches accounts and requests a fingerprint or password.

Ultimately, I have to log into any of my accounts with a password since my fingerprint no longer works.

I know you aren't having that issue but many of us are. ****

Thanks!

After upgrading my M1 iMac to Sonoma 14.0 the fingerprint button just disappeared, and there is no way to reactivate it. Problem persists even after upgrading to 14.1. There's clearly a bug here!

same here with mac studio m1 max with magic keyboard running sononoma 14.0.

i have tried to delete the fingerprint and add a new one. after deleting the old fingerprint, i am facing the problem that i cannot add a new one.

Worker perfectly and first try for me:

1. switch keyboard off
2. plugin in the keyboard to the mac
3. switch keyboard on
4. unplug keyboard from the mac

Bingo. Done.

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.

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.
