If the Caps Lock on your MacBook Air is still stuck or it only works temporarily, read on to get more information.

Open the Apple menu > System Preferences, click Accessibility > Keyboard, select Viewer and tick the box next to Enable Accessibility Keyboard.

If the Shift or Caps Lock key is highlighted as being pressed, try clicking to unstick it and see whether it resolves the issue. You can also clean the debris under the keys with a can of compressed air. 

If that's not helping, chances are that your keyboard has hardware problems. You can take the chance with other solutions below before heading for repair. If no key appears to be stuck, move on to the next fix.

Way 3: Reset NVRAM and SMC

NVRAM stores your Mac's startup-disk selection and peripheral data such as volume, screen resolution, time zone, etc. Resetting it has been proven to be an efficient resolution to fix MacBook Pro stuck in Caps Lock. Note that you only need to shut down your Mac and then power on again to reset NVRAM on an M1 Mac. Here's how to reset NVRAM on Intel Macs:

  1. Shut down your Mac.
  2. Press the power button, then immediately hold down Option-Command-P-R.
  3. Release the keys and allow your Mac to start up normally 1) when you hear the second startup sound on a non-T2 Mac. 2) after the Apple logo appears and disappears for the second time on a T2 Mac.
  4. Check your Startup Disk, Display, and Date & Time in System Preferences.

Now, you can type again to see if you have fixed Caps Lock stuck on Mac. If not, try resetting the SMC, which is responsible for the physical parts of your Mac, such as the battery, keyboard, fan, power management, etc.

Way 4: Disable Caps Lock

Another thing you can try to stop your MacBook Pro from getting stuck in Caps Lock is to disable the Caps Lock key and then re-enable it when needed. To do that, follow these steps.
