What to Do if Your Magic Keyboard With Touch ID Isn’t Working

Apple Magic Keyboard with Touch ID - Green

I recently wrote an article on my 24-inch iMac when the Magic Keyboard with Touch ID quit working. I tried several steps to fix the issue:

  1. I quit and relaunched Pages (the app I was using when the problem started).
  2. I powered off, then powered back on the Magic Keyboard.
  3. I restarted my iMac.
  4. I powered off, then powered on, the all-in-one iMac. 
  5. I disabled Bluetooth, then re-enabled it. To do so, follow these steps:
    • From the Apple menu (), open System Preferences and choose Bluetooth.
    • Click the option to “Turn Bluetooth Off” (if it’s already off, there’s your problem).

    • Wait for a second and turn Bluetooth back on. Your Magic Keyboard and other Bluetooth devices should show up in the right side of the Bluetooth panel.

Still Not Working?

If your Magic Keyboard still isn’t working — and it wasn’t for me — connect your keyboard to your Mac with the Lightning to USB Cable or USB-C to Lightning Cable. Wait 1 minute, then disconnect the cable. 

This pairs the accessory with your Mac and charges the built-in battery. To check your accessory’s charge level, click the Control Center icon in the menu bar, then click Bluetooth.

That worked for me. As I said, this was accomplished on a 24-inch iMac, but, hopefully, it will work for you, as well.

  • Dennis,

    Under Step 5, how did you manage to turn bluetooth back on if it was turned off, thus disabling the control input to the bluetooth switch to turn it back on again?

    I was working on another bluetooth matter and inadvertently turned bluetooth off, thus completely disabling all control inputs to my iMac. I simply couldn’t access it, apart from the power switch, which achieved no control inputs whatsoever. I had to go out and buy a wired mouse to access the bluetooth switch to activate that system again and thus regain control of my iMac. The Apple Magic Keyboard does act as a wired unit when connected through its Lightning charging cord, but it was the mouse I needed to click that switch! Just in case I ever forget, that wired mouse is staying in my parts drawer now!!

  • Remember, a fingerprint (or Face ID) won’t give you the legal protection of a Passcode… From a legal perspective, you’re LESS secure unlocking a Mac or iPhone with a fingerprint or your face — or any biometric mechanism — than with a passcode.   Passcodes are considered “testimonial” evidence based on the contents of your thoughts. But in multiple cases, people have been ORDERED to unlock a phone via Face or fingerprint, under the reasoning that their fingerprint (or your face) is a piece of physical evidence. Yes, measures can be taken to disable the biometric mechanism, will you have the time to do that? Will you be allowed to do that? Be safe, use a passcode.
