If Touch ID on your Mac stops working, it can be frustrating but there are several reasons that could cause this issue. That includes software glitches, dirty sensors, or system settings problems, all of which have different steps that you can take to fix it.
First, check if Touch ID is enabled in your system settings and ensure that automatic login is off. If the settings are correct, try adding your fingerprint again. Sometimes, a simple restart can solve the problem. If not, you may need to update your Mac’s software. In rare cases, there could be a hardware issue with the Touch ID sensor. If you’ve attempted everything and it still doesn’t work, contacting Apple support for assistance may be necessary.

Setting Up Touch ID on Your Mac
Touch ID lets you use your fingerprint to unlock your Mac and make secure purchases. It’s quick to set up and easy to use.
Enabling Touch ID
Go to the Apple menu and open System Settings. Click Touch ID & Password. Turn on the option to use Touch ID to unlock your Mac. You may need to enter your password first. If you don’t see Touch ID settings, check that your Mac model supports it. Most newer MacBooks have Touch ID built in.
Make sure Automatic login is off. Go to Users & Groups in System Settings. Click Login Options. Turn off Automatic login if it’s on. This helps keep your Mac secure.
Adding and Managing Fingerprints
To add a fingerprint, click Add Fingerprint in Touch ID settings. Follow the onscreen steps. Place your finger on the Touch ID sensor several times. Move it slightly each time. This helps your Mac recognize your print from different angles.
You can add up to 5 fingerprints. Give each one a name to keep track. To remove a print, click the X next to its name. You can also turn Touch ID on or off for specific tasks like unlocking your Mac or making purchases.
If Touch ID isn’t working, try turning your Mac off and on. For external keyboards with Touch ID, unplug it and plug it back in. You may need to wait 10 seconds for Touch ID to work again.
Troubleshooting Touch ID Issues
Touch ID problems on Macs can often be fixed with a few simple steps. Here are some ways to get your fingerprint sensor working again.
Common Touch ID Problems
Touch ID may stop working if your finger is wet or dirty. Dry your hands and clean the sensor with a soft cloth. Cuts, dry skin, or lotion on your finger can also cause issues. Try using a different finger if this happens.
Sometimes Touch ID won’t work after your Mac wakes from sleep. To fix this, go to System Settings > Touch ID & Password. Turn off the “Use Touch ID to unlock your Mac” option. Restart your Mac. Then turn the setting back on.
If Touch ID still fails, check that Automatic Login is off. Go to System Settings > Users & Groups > Login Options to disable it.
Hardware and Software Considerations
Outdated software can cause Touch ID problems. Make sure your Mac has the latest macOS version installed. Go to System Settings > Software Update to check.
For external keyboards with Touch ID, ensure the keyboard is properly connected. Try unplugging it and plugging it back in.
If issues persist, reset your Mac’s SMC and NVRAM. To do this:
- Shut down your Mac
- Hold the power button for 10 seconds
- Release and wait a few seconds
- Turn your Mac back on
Advanced Solutions
If basic fixes don’t work, try these advanced steps:
- Create a new user account and test Touch ID there.
- Boot into Safe Mode to see if the problem is caused by third-party software.
- Use Terminal to reset Touch ID settings:
- Open Terminal
- Type:
sudo pkill -9 -f "Touch ID" - Enter your password when prompted
If none of these work, your Touch ID sensor may be faulty. Contact Apple Support or visit an Apple Store for help.
