Fix Touch ID Stopped Working to Unlock by Single Touch in macOS Sonoma

This is a major issue that many users are facing after updating to the macOS Sonoma. If you are also facing issues with the Touch ID after the macOS Sonoma update, then here’s what you can do to fix it-

Restart your System

Restart mac

First thing first, you should restart your Mac without any delay. If you are facing this issue after the update, it can be due to some minor glitch caused after the update. A system restart should most probably resolve it, so you should do that. If you have already tried that and it doesn’t seem to fix the issue, try the second step mentioned in this guide. 

Clean the Touch ID Sensor

If Touch ID is working but taking some time to recognize your fingerprint or not unlocking in a single touch, then probably your Touch ID sensor is dirty. Dirt and dust on the Touch ID sensor can cause this issue, as the sensor won’t be able to read your fingerprint properly. 

You can use a clean microfibre cloth to wipe off any dirt on the surface of the sensor. If the dust is stuck on the surface, then you can use a cleaner like the one that you use for other digital devices. 

Also, while using the Touch ID, ensure your finger is clean. If your finger is dirty, then that can also cause. Ensure you clean your fingers and then proceed with using the Touch ID. 

Check for Software Update

Apple Developers always work towards fixing the bugs that were in the previous update by releasing new updates frequently. You can try checking for the macOS update and installing the available update if Sonoma Touch ID stopped working to unlock by a single touch. To do so, follow the steps given below to do so-

macOS Touch ID

Reset SMC

SMC or System Management Controller handles various components of your Mac, including power supply, status lights, USB ports, etc. If something goes wrong with the SMC, then that can cause issues with the Touch ID. In that case, you will have to reset the SMC, and the issue will be solved. 

If you have a Mac with Apple Silicon, resetting the SMC is not required. A system restart would do the job. However, for Macs with an Apple T2 chip or Intel-based processor, you will have to reset the SMC. Before you continue, you will have to check whether your Mac has an Apple T2 chip or not.

On Mac Desktop Computers (without Apple Silicon)

  • First, shut down your Mac. 
  • After this, unplug the power cord and wait for 15 seconds. 
  • Now, plug the power cord back into your Mac. 
  • Turn on your Mac after 5 seconds. 

On MacBooks (without Apple Silicon)

  • The first step is to shut down your MacBook. 
  • Once off, press and hold the Control + Option + Shift keys together. While holding these three keys, press and hold down the Power key. 

Reset SMC on Mac

  • You must hold the keys for 10 seconds and then release them. 
  • After you release the keys, press the Power button on your Mac to turn it on. 

Reset NVRAM (Or PRAM)

Another thing that you have to do if you cannot solve this issue is resetting the NVRAM (or PRAM). This isn’t generally an issue with the Macs with Apple Silicon; if you are using a Mac based on Intel chips, then you will have to manually reset the NVRAM. Below are the steps to do so-

  • First, shut down your Mac. 
  • Press the Power button on your Mac, and then immediately press and hold the Option + Command + P + R keys together. 
  • Keep holding the keys for 20 seconds, and then release them. You will get a sign to release them if you get the startup sound or Apple Logo more than once. 
Final Words

If, after upgrading to macOS Sonoma, Touch ID is not working or you are facing a problem unlocking it by single Touch, then you should be able to solve this issue through the above steps. If the issue is still not solved, then you can contact Apple support or visit the nearest Apple Service Center and get your issue resolved by the experts.
