What should I do first if my Mac keyboard stops working?
If your Mac keyboard stops working, the first step is to check the connection. If you’re using a wired keyboard, ensure that it’s plugged into a functioning USB port. You might also want to try plugging it into a different port or using a different cable if available. For wireless keyboards, check if the keyboard is turned on and has sufficient battery power. Sometimes a simple restart of your Mac can also resolve connection issues.
After you’ve confirmed the connection, check for any visible damage to the keyboard. Look for stuck keys or if any debris is affecting the keyboard’s performance. You might want to clean the keyboard lightly, using compressed air to remove dust and particles. If the keyboard is still unresponsive, try connecting a different keyboard to isolate whether the issue lies with the keyboard itself or your Mac.
How do I reset my Mac’s keyboard settings?
Resetting your Mac’s keyboard settings can often solve various issues. To do this, go to the “System Preferences” and then select “Keyboard.” Here, you can adjust the keyboard settings and reset them to defaults. Additionally, you can remove any custom shortcuts you may have set that could conflict with regular typing. This reset will help ensure that your keyboard commands behave as expected.
Another approach is to delete the keyboard preferences file. To do this, head to your Finder, navigate to the “Library” folder, then to “Preferences,” and look for a file named “com.apple.keyboardtype.plist.” Deleting this file can force your Mac to regenerate it with default settings. Always ensure you back up any important data before making changes to system files.
What if my Mac’s keyboard is not responding at all?
If your Mac’s keyboard is not responding at all, it could be due to a system process issue. Boot your Mac into Safe Mode by restarting and holding the Shift key. This can help determine if any third-party software might be causing the issue.

Make sure to maintain a safe distance while using compressed air to avoid moisture buildup.
For a more thorough cleaning, use a soft, lint-free cloth slightly dampened with isopropyl alcohol. Gently wipe down the keys and surrounding surfaces. Avoid using excessive liquid, as it could seep into the keyboard. If necessary, you can also use cotton swabs to carefully clean around the keys. Allow the keyboard to dry completely before reconnecting it to your Mac.
What should I do if my Mac keyboard is under warranty?
If your Mac keyboard is under warranty and you are experiencing issues, it’s best to contact Apple Support or visit an authorized service provider. They can run diagnostics to determine if the problem is covered by your warranty. If a hardware fault is detected, the keyboard may be repaired or replaced at no cost, depending on the terms of your warranty.
Before reaching out, ensure that all troubleshooting steps have been taken, as this can ease the process when communicating with support. Keep records of your purchase and receipts handy, as these may be requested. If you’ve made modifications to your Mac, be prepared to discuss those, as they may affect warranty eligibility.
Is it worth buying a new keyboard if mine is malfunctioning?
Deciding to buy a new keyboard depends on the extent of the issues and the value you place on productivity. If the keyboard is showing consistent signs of malfunction despite troubleshooting, and if it’s older or heavily used, investing in a new keyboard might be worth considering. Weigh the costs of purchasing a new keyboard against the time and frustration of working with a malfunctioning one.
However, before purchasing a new one, evaluate whether your current keyboard can be repaired. Sometimes, simple fixes or cleaning can resolve issues effectively. If your keyboard is wireless, consider the life of the current batteries and if they need replacement. Look into warranty options as well, as you may be eligible for a replacement without additional costs.
