Touch ID is one of Apple’s most convenient features, allowing users to unlock their Mac, authorize purchases, and log in to apps quickly and securely using just their fingerprint. However, when Touch ID stops working on your Mac, MacBook, or Magic Keyboard, it can become a frustrating issue.
Whether you’re using a MacBook Pro, MacBook Air, or an external keyboard with Touch ID, this article will walk you through all the potential reasons why Touch ID might not be working—and how to fix it.
Why Is Touch ID Not Working on My Mac
There are several common reasons why Touch ID might stop working on your Mac. Let’s explore the most frequent ones:
1. Hardware Issues
If your Mac’s fingerprint reader or Touch ID sensor is physically damaged, it may not be able to read your fingerprint accurately. Cracks, dust, or moisture on the sensor area can disrupt its functionality.
Solution: Clean the Touch ID sensor gently using a soft, lint-free cloth. Avoid using liquids. If the sensor is visibly damaged, contact Apple Support.
2. macOS Update Problems
After a major macOS update, some users report issues with biometric features, including Touch ID. Bugs or conflicts with new system files can cause temporary malfunctions.
Solution: Check for additional macOS updates that might include bug fixes. Go to System Settings > General > Software Update and install any available updates.
3. Incorrect Security Settings
In some cases, changes to your security or privacy settings might prevent Touch ID from functioning correctly.
Solution: Go to System Settings > Touch ID & Password and make sure that Touch ID is enabled for unlocking your Mac, Apple Pay, iTunes, and App Store.
4. Dirty or Wet Finger
If your finger is wet, dirty, or greasy, the sensor might not be able to read your fingerprint accurately.
Solution: Wash and dry your hands, then try again.
5. Compatibility Issues with Accessories
Third-party peripherals like USB hubs, docking stations, or non-certified keyboards may interfere with the Touch ID signal.
Solution: Disconnect all external accessories and try using Touch ID again.
MacBook Touch ID Not Working — Air, Pro, and Other Models
Touch ID issues can vary depending on the model of your MacBook. Here’s how to troubleshoot for specific devices:
MacBook Pro Touch ID Issues
Many users report that Touch ID on the MacBook Pro becomes unresponsive after the device wakes from sleep or restarts.
Solutions:
- Restart your MacBook Pro.
- Delete and re-add your fingerprint.
- Check for Touch Bar errors, as some models have an integrated sensor.
MacBook Air Touch ID Problems
The MacBook Air uses the same technology, but it may behave differently due to internal component layouts and software configurations.
Solutions:
- Ensure you’re using the latest version of macOS.
- Remove cases or covers that might be interfering.
Common Across Models
- Reset the SMC (System Management Controller): On Intel Macs, shut down your Mac and press Shift + Control + Option + Power for 10 seconds. On Apple Silicon, simply restart.
- Check if Touch ID works in Safe Mode.
Touch ID Not Working on Apple Keyboard
The external Magic Keyboard with Touch ID only works with specific Mac models, particularly those with Apple silicon (M1, M2, etc.).
Compatibility Checklist
- Your Mac must have an M1 chip or newer.
- You must be running macOS 11.4 or later.
Connection Problems
If your keyboard isn’t properly connected via Bluetooth or USB, the fingerprint reader won’t work.
Solutions:
- Re-pair your keyboard via System Settings > Bluetooth.
- Connect the keyboard via USB-C and wait for macOS to configure it.
- Ensure your keyboard is fully charged.
Reset Keyboard and Reconfigure Touch ID
- Go to System Settings > Touch ID & Password.
- Delete any existing fingerprints.
- Add a new fingerprint.
If Touch ID still doesn’t work, try resetting the keyboard’s Bluetooth connection or updating your Mac’s firmware.
How to Reset and Set Up Touch ID on MacBook Pro
Sometimes, Touch ID simply needs to be reset and reconfigured. Here’s how to do that properly.
Step 1: Remove Existing Fingerprints
- Go to System Settings > Touch ID & Password.
- Click the “X” next to each fingerprint to remove it.
Step 2: Add a New Fingerprint
- Click Add Fingerprint.
- Follow the on-screen instructions to scan your fingerprint.
- Make sure your finger is clean and dry.
Step 3: Enable Touch ID for All Features
- Enable Touch ID for unlocking your Mac, Apple Pay, password autofill, and App Store purchases.
Step 4: Restart Your Mac
Restarting often resolves residual glitches that prevent Touch ID from functioning.
Optional: Reset NVRAM or SMC
On Intel Macs, resetting NVRAM or the SMC can help resolve Touch ID issues:
- NVRAM: Restart and hold Option + Command + P + R for 20 seconds.
- SMC: Shut down, then press Shift + Control + Option + Power for 10 seconds.
Why Isn’t My Touch Bar Working — And Does It Affect Touch ID?
On some MacBook Pro models, the Touch ID sensor is integrated into the Touch Bar. If the Touch Bar isn’t working, it could affect Touch ID.
How to Fix Touch Bar Issues
- Restart your Mac.
- Reset the SMC and NVRAM.
- Use Terminal to restart the Touch Bar process:
sudo pkill TouchBarServer
- Check for system updates.
If none of these work, contact Apple Support.
Conclusion
Touch ID is a great convenience—until it stops working. Thankfully, most problems with Touch ID on MacBooks, Mac desktops, or external keyboards can be resolved with basic troubleshooting steps like cleaning the sensor, resetting fingerprints, or updating software.
If you’ve tried all of the above and still face issues, it might be time to visit an Apple Store or authorized service provider. Persistent issues may indicate deeper hardware problems that require professional repair.
