Clean the magic keyboard

The Magic Keyboard is not as susceptible to dust as Apple keyboards with butterfly switches. But if Magic Keyboard Caps Lock is completely unresponsive, applying a few short puffs of compressed air under the key won’t hurt.

Reset the Mac’s NVRAM

If none of the previous solutions worked, the problem could be your Mac’s NVRAM (Non-Volatile Random Access Memory). NVRAM contains system-critical data that can become outdated and cause problems with external devices. If you are using an Intel-based Mac, you have the option to reset it manually.

1. Turn off your Mac.

2. Turn it on, but immediately hold down the button Command, Option, P.And R. keys.

3. Keep holding the keys until you hear the Mac sound twice. If your Mac uses an Apple T2 security chip, release it as soon as you see the Apple logo for the second time.

If resetting NVRAM does not resolve the Caps Lock key on the Magic Keyboard, perform a System Management Controller (SMC) reset.

Contact Apple Support

If none of the above solutions helped fix the Cap Lock on your Magic Keyboard, it’s time to contact Apple Support for assistance. You are probably dealing with a Caps Lock or a faulty circuit inside the device. If your Magic Keyboard is within the warranty period, you will likely receive a replacement.
