First introduced on the iPhone 4S a decade ago, Touch ID is an authentication tool found on all modern iPhones, select iPads, and Macs, including the 2021 iMac. The tool has various features, including the ability to unlock your device, use Apple Pay, log into third-party apps, and make purchases on the different Apple online stores.
Touch ID Issues: Basic Troubleshooting
Once you set up Touch ID on your Mac, you might never run into any problems. And yet, they do occur. Often, things can get easily resolved by cleaning the Touch ID button on the keyboard or resetting the tool. However, other possible solutions will take more time and require tackling various steps.
Time to Clean
Over the years, Apple has made Mac keyboards more durable and less prone to malfunction. However, our fingers aren’t exactly the cleanest part of our bodies. They contain oil and are sometimes wet, which could cause issues. You should clean your Mac keyboard regularly and be sure to wash your hands throughout the day. The keyboard should be cleaned just as you would a mouse or other computer accessory to remove dirt or debris.
Reboot
Restarting a computer is a great way to resolve various issues, including those dealing with Touch ID. By doing so, your computer resets different functions, and this might be the troubleshooting step you need to resolve the present issue. Follow these steps to reboot:
Turn off your Mac using the Apple menu > Shut Down command.Press and hold down the power button for 10 seconds, then release it.After a few seconds, press the power button to restart your Mac.
