Are you still having trouble with the Caps Lock key on your Magic Keyboard? Maybe it doesn’t respond while typing. Or maybe it’s just the LED indicator, which may stay on constantly or not light up at all.
Incorrectly associated modifier keys, a faulty Bluetooth connection, outdated system software, and many other reasons can cause the Magic Keyboard’s Caps Lock to not work.
Unless the Caps Lock on your Magic Keyboard looks broken, you can try to fix the problem yourself. The troubleshooting tips below apply to the following scenarios:
- The Caps Lock key does not respond and the LED indicator stays on.
- The Caps Lock key does not respond and the LED indicator remains off.
- The Caps Lock key is responsive, but the LED indicator is always on.
- The Caps Lock key is responsive, but the LED indicator is always off.
Note: If you’re troubleshooting the Magic Keyboard built into your MacBook Air or Pro (2020 or later), skip the fixes that don’t apply.
Check your Mac modifier key settings
Is the Caps Lock of your Magic Keyboard not fully responding? If so, it’s best to start by checking if the key is set correctly on your Mac and not simply associated with a different editing action (like Control, Option, or Command).
1. Open the Apple menu and select System Preferences.
Alternatively, select the Restore default settings to reset the changes to all modifier keys on the Magic Keyboard.
Turn the magic keyboard off and on again
Next, try turning the Magic Keyboard off and on again. Often, this eliminates problems that randomly occur with unresponsive keys or a faulty LED indicator. You can find the Power switch on the front right edge of the device.
After turning off the Magic Keyboard, wait up to 10 seconds before turning it back on. It will automatically reconnect to your Mac.
Connect Magic Keyboard to Mac via USB
Do you have the Lightning cable of your Magic Keyboard handy? Try using it to establish a connection via USB. If the Caps Lock key starts working correctly afterwards, disconnect the cable and go back to using the Magic Keyboard via Bluetooth.
Reset the Bluetooth module of the Mac
An unstable Bluetooth module on the Mac can end up causing all kinds of problems like magic keyboard caps lock not working. However, you can try to restore it by opening the Mac Control center holding down the Move And Option keys and expanding the Bluetooth check. Follow it by selecting Reset Bluetooth module.
If the option appears to be missing, run the following command in Terminal (open the Springboard and select Other > terminal) instead:
sudo pkill bluetoothd
Your Bluetooth devices will disconnect and reconnect after a few seconds. Try using the magic keyboard and see if the problem returns.
Reset Magic Keyboard to factory settings
You can also try resetting your Magic Keyboard (including any other Apple devices you connected via Bluetooth) to factory settings.
Again, open your Mac Control centerhold down the Move And Option buttons, but this time select Factory reset of all connected Apple devices. If the option isn’t available on your Mac, move on to the next fix.
Restart your Mac
If the Caps Lock key on your magic keyboard still doesn’t respond or the LED indicator stays stuck, it’s a good idea to restart your Mac. Then save your work, open the Apple menu and select Restart. Then, select Restart once again to confirm.
Update the Mac system software
The macOS update not only fixes any known bugs with your Mac’s Bluetooth module, it also contains firmware updates for the Magic Keyboard.
If you haven’t updated your Mac recently, open the file System Preferences app and select Software update. If you see a new update, select Update now. If Software Updater fails, find out what you can do to fix blocked macOS updates.
Reconnect Magic Keyboard to Mac
Completely disconnecting and reconnecting the Magic Keyboard to the Mac can also repair a damaged Bluetooth connection.
1. Open the Apple menu and select System Preferences.
2. Select Bluetooth.
3. Select X next to your magic keyboard.
4. Select To remove to unpair the Magic Keyboard from your Mac.
5. Turn the Magic Keyboard off and on again. It should momentarily appear on the Bluetooth screen. To select Connect when it does.
Delete your Mac’s Bluetooth preferences
The following fix involves deleting your Mac’s Bluetooth preferences file. This is another way to improve the reliability of Bluetooth devices.
1. Open a seeker window and select to go > Go to the folder on the menu bar.
3. Locate and move the following file to the Mac’s Trash:
4. Restart your Mac.
5. macOS will automatically recreate a new Bluetooth preferences file. You can always restore the deleted file from the Recycle Bin if you later encounter further problems.
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.
