Since a keyboard not working can be caused by various factors, you need to do troubleshooting and take all possible causes into consideration.

  4. Restart your Mac
  5. Reset keyboard settings
  6. Delete the keyboard-related PLIST files
  7. Delete recently installed software

When all the keys on the keyboard are not working, the prior thing you need to do is to check the connections between your keyboard and Mac computer.

Check the USB connection

If you use a USB keyboard, you can replug your wired keyboard to another USB port on your Mac. If the keyboard still has no response, change a USB cable. Also, you can connect the USB cable to another Mac to check if works well. If not, your USB keyboard may have hardware issues, you can change a new one.

Check the Bluetooth connection

If you have a wireless keyboard, you should check the Bluetooth connection. Go to the Apple menu > System Preferences > Bluetooth. If your wireless keyboard can't be detected by Bluetooth, you can turn the Bluetooth off and then on. Then, connect the keyboard.

If your keyboard shows up in the devices list in Bluetooth, disconnect it by clicking the close icon beside the keyboard and then pair it to your Mac again.

Clean your keyboard

Maybe you have used your keyboard for a long time and the dust and dirt are scattered in the keyboard crevices, leading to your MacBook Pro keyboard not working

You can use a professional keyboard cleaning tool to clean up your keyboard. And then, check if your Mac goes work now.

Check the battery on your wireless keyboard

There's one thing you may ignore. That is the battery on your wireless Apple keyboard has insufficient power. Therefore, your keyboard reacts slowly when you hit a key or even doesn't respond.

You can change a battery and reconnect the keyboard to your Mac. Then, your keyboard will perform well as usual.

Restart your Mac

If your Mac keyboard doesn't have connection and hardware issues but still can't be put into use, check if the tiny errors on your Mac are the culprits.

In that case, you can restart your Mac to bring the macOS to a refreshed state.

Reset the keyboard settings

If your keyboard is not absolutely unresponsive but reacts very slowly, you can reset the keyboard settings to adjust the amount of time between a key's hit and reaction.

To reset the keyboard settings, open the Apple logo > System Preferences > Accessibility > Keyboard > Hardware. Then, uncheck in the Enable Slow Keys option.

Reset the keyboard-related PLIST files

A PLIST file is also called the setting file that contains the preferences data of an app or program on Mac. When the program runs abnormally, it is necessary to check if its PLIST file is corrupted.

For a problematic Mac keyboard, you can delete the related PLIST files. Go to open Finder and click Go from the Finder menu > Go to Folder. Then, enter ~/Library/Preferences/ and click Go. Find and delete the com.apple.keyboardtype.plist, com.apple.keyboardservicesd.plist, and other keyboard-related PLIST files.

After that, restart your Mac to allow these deleted PLIST files to be automatically recreated. Now, check if your keyboard acts well now.

Delete the recently installed third-party software

Some third-party apps can make conflicts with your Mac, making your Mac keeps crashing or the keyboard not working. 

If you want to clear out that if the third-party apps interfere with your use of the keyboard, try to uninstall these apps from your Mac.

Update your Mac

If you've tried the all way above even having changed a keyboard, the keyboard still not working at the login screen or during Mac startup. You should consider if the bugs of the current macOS version lead to this issue.

Some users report that the keyboard is not working after a macOS update. If you also encounter this situation, go for updating your Mac to the latest update. Usually, the new update carries the bug patches and security updates.

You can select the Apple menu > System Preferences > Software Update and click Update Now or Upgrade Now.
