Troubleshooting the iMac M1 TouchID Issue
Fortunately, there are several troubleshooting steps you can take to try and resolve the iMac M1 TouchID issue. These steps can be categorized into software and hardware-related solutions:
Software Troubleshooting
-
Restart your iMac: A simple restart can often resolve software glitches, including the TouchID issue.
-
Update macOS: Ensure your iMac is running the latest version of macOS. Updates often include bug fixes and improvements that could address TouchID issues.

Remove and re-add fingerprints: Go to System Settings > Touch ID & Passcode and remove all existing fingerprints. Then, re-add your fingerprints to ensure they're properly registered.
-
Disable and re-enable Touch ID: In System Settings > Touch ID & Passcode, disable Touch ID and then re-enable it. This can sometimes refresh the sensor's functionality.
-
Check for software conflicts: Certain third-party apps could interfere with the TouchID functionality. Try temporarily disabling any recently installed applications and see if the Touch ID starts working.
-
Reset the TouchID sensor: This will erase all stored fingerprints and reset the sensor to its factory settings. To reset the Touch ID sensor, you can use the following steps:

- Check for physical damage: Inspect the Touch ID sensor for any signs of damage or wear and tear. If you find any, it could be a hardware issue that requires professional repair.
- Connect an external keyboard with Touch ID: If you have an external keyboard with Touch ID, connect it to your iMac. If the Touch ID works with the external keyboard, it suggests the issue is with your iMac's Touch ID sensor.
