Apple's Touch ID fingerprint sensor technology has been a smart inclusion since the iPhone 5S, extending to all subsequent devices like the iPhone 7, iPhone 7 Plus, iPad Air, and more.
Touch ID is integrated into the HOME button of the device, offering biometric authentication capabilities. Instead of entering passwords to access your device or download apps from the App Store, you can now simply place your finger on Touch ID to swiftly accomplish these tasks.
Apple's breakthrough this year includes bringing Touch ID to the MacBook Pro 2016. However, Touch ID functionality on MacBook Pro operates quite differently compared to iOS.
Fixing Touch ID Not Working on MacBook Pro 2016
While the sensor area on the iPhone is just a ring around the home button, on MacBook Pro, it encompasses the entire button. Because it scans the entire finger, Touch ID sometimes encounters glitches, preventing you from unlocking your device or making transactions on the App Store or Apple Pay.
Don't rush to blame your device; instead, follow the steps below to troubleshoot Touch ID not working on MacBook Pro 2016.
Note: Touch ID is a non-recoverable password type. Therefore, in addition to Touch ID, you should have an additional traditional password as a backup precaution.
Checking Touch ID Settings
First, you need to verify if Touch ID is enabled for use on the apps you desire.
In the MacBook's Apple menu, select System Preferences => Touch ID.
Check all three options to use Touch ID for Apple Pay, iTunes & App Store, and device unlock.
Touch ID Not Working on App Store or Apple Pay
If you've checked and selected all three options, but Touch ID still doesn't work on App Store or Apple Pay, restart the app. Alternatively, restart your MacBook.
Reset Touch ID on MacBook
The best way to resolve Touch ID not working is to reset the current fingerprint recognitions. Follow these steps:
Step 1: Delete current fingerprints on MacBook Pro by holding the mouse over the fingerprint mark until the 'x' appears. Click on it, enter the password, then select Delete.
Step 2: Press Add a new fingerprint in the Touch ID section to add a new one, enter the password, then place your finger on the Touch ID button to scan the new fingerprint.
Incompatible Accessories
Touch ID on MacBook Pro has been significantly improved, so you don't need to place your finger on the edge for recognition like with the iPhone. The entire area on the Touch ID button can recognize fingerprints.
Certain types of MacBook cases and covers that are not compatible may cover the Touch ID area and cause it to stop working. Remove these accessories and choose ones that are more suitable for your device.
Incorrect Touch ID or Touch ID not working after macOS update
Try using different fingerprints that have been set up.
If unsuccessful, try restoring or installing a new macOS Sierra operating system. If the issue persists, contact the nearest Apple store or service center for assistance.
Touch ID Slow, Lagging
Many users complain about this issue when Touch ID fingerprint scanning is slow and often fails on the first attempt. The advice given is to regularly change Touch ID once a month on MacBook Pro. You can also apply this advice to iPhone 6 and iPhone 5S devices.
Notes on Using Touch ID
When using Touch ID, both your finger and the Touch ID sensor area must be dry. Pay attention to regularly clean the Touch ID sensor area on your device.
When rescanning fingerprints, carefully scan the entire fingertip surface for the system to accurately retain the fingerprint. Lift your finger, then place it down slower when adding fingerprints to the system.
When the system confirms, keep your finger on Touch ID until successful.
