- Make sure “Slow Keys” and “Sticky Keys” are turned off if you don’t need them.
7. Create a New User Account
Creating a new user account can help determine if the problem is user-specific. If the keyboard works in the new account, your issue lies within the original account’s settings.
When All Else Fails: Hardware Repair Considerations
If none of the software solutions work, you might be facing a hardware malfunction. Here’s what you can consider next:

What are the common reasons for a Mac keyboard not working?
There are several common reasons why your Mac keyboard may not be functioning properly. One of the most frequent issues is a low battery if you are using a wireless keyboard. Checking the battery status or replacing the batteries can often resolve connectivity problems. Additionally, physical damage or debris underneath the keys can hinder proper operation, leading to non-responsiveness.
Another possibility is a software issue, which can arise after a macOS update or changes in settings. Sometimes, specific applications may also interfere with keyboard functionality. Restarting your Mac can help to refresh the system and resolve minor software glitches. If issues persist, it may be worth checking the keyboard settings in System Preferences or performing a safe boot to identify further complications.
How can I troubleshoot my Mac keyboard?
Start by checking the basic connections, especially if you’re using a wired keyboard. Ensure that the keyboard is properly plugged into the USB port and that there are no issues with the port itself. Testing the keyboard on another Mac can help determine if the issue lies with the keyboard or your Mac. For wireless keyboards, make sure Bluetooth is enabled and that your keyboard is paired with your Mac. You can do this by accessing the Bluetooth settings in System Preferences.
If the connections are not the problem, try resetting the keyboard settings. Navigate to System Preferences, select Keyboard, and then click on “Modifier Keys” to reset any custom key configurations. Additionally, consider resetting the NVRAM/PRAM on your Mac, which can help resolve various keyboard-related issues. To do this, restart your Mac and immediately hold down Option, Command, P, and R keys until you hear the startup sound a second time.
What should I do if some keys work but others don’t?
If you find that only specific keys on your Mac keyboard are malfunctioning, it may indicate a hardware issue with those particular keys. Debris or dust trapped beneath the keys can prevent them from functioning correctly, so gently cleaning the affected area might help restore normal operation. Using compressed air can be effective for dislodging dirt without damaging the keyboard.
If cleaning does not resolve the issue, software could also be to blame. Sometimes, modified key settings or third-party software can interfere with keyboard performance. You can try going to System Preferences, selecting Keyboard, and checking the Key Repeat and Delay Until Repeat settings to ensure they are set to default values. If problems continue, consider testing the keyboard in a different user account or on another Mac to pinpoint the problem.
What if my Mac keyboard is unresponsive after an update?
If your keyboard becomes unresponsive following a macOS update, it’s possible that the update has introduced a bug affecting keyboard functionality. Begin by restarting your Mac, as this simple step can often rectify minor update-related glitches. If restarting doesn’t work, consider checking if there are any additional updates available, as Apple frequently realizes patches to fix such issues.
If the problem persists, explore booting your Mac in Safe Mode. To do this, restart your Mac and hold down the Shift key until you see the login screen. This mode only loads essential software and can help determine if a third-party application is causing the keyboard issues. If the keyboard works in Safe Mode, consider uninstalling any recently installed applications or running the Disk Utility to check for and repair any disk errors.
Are there any settings that could be affecting my keyboard’s performance?
Yes, various settings on your Mac can affect keyboard performance. For instance, keyboard shortcuts and accessibility options may conflict with the normal function of the keyboard. Check the Keyboard section in System Preferences for any custom shortcuts you’ve established that may be causing issues. If you’ve enabled Sticky Keys or Slow Keys under Accessibility settings, it might affect how your keyboard responds.
Additionally, if you’re using third-party applications that modify keyboard behavior, such as keyboard remapping software, these could cause conflicts. Disabling or uninstalling these applications may resolve the problem. Also, make sure that your keyboard layout is set correctly in System Preferences to avoid inadvertent input issues related to incorrect layouts.
When should I consider replacing my Mac keyboard?
If you’ve tried all troubleshooting steps without success, it may be time to consider replacing your Mac keyboard. Physical damage, such as broken keys or unresponsive areas that persist after cleaning, could indicate that repairs are necessary. In such cases, purchasing a new keyboard may be more practical than trying to fix an unresponsive one.
On the other hand, if your keyboard consistently encounters software issues, it can affect overall productivity and workflow. If you’ve already invested time in troubleshooting and the problems continue, it might be more efficient to buy a new keyboard rather than deal with ongoing frustrations. Always consider your usage needs and choose a keyboard that complements your Mac setup for optimal performance.
