A Mac keyboard that suddenly stops working can feel like a major roadblock, especially when you rely on your device for work, school, or creative projects. Before you panic, take a deep breath—most keyboard issues can be resolved with simple troubleshooting steps.
Whether you’re dealing with unresponsive keys, lagging input, or connection problems, this guide will walk you through everything you need to know to get your Mac keyboard working like new.
Diagnose the Problem:
Before diving into solutions, take a moment to figure out what’s causing the issue. Here are a few common scenarios:
- Hardware Malfunction: Physical damage, such as liquid spills or wear and tear, could be the culprit.
- Software Glitches: System bugs or misconfigured settings may interfere with keyboard functionality.
- Connectivity Issues: If you’re using a wireless keyboard, the problem might lie in its connection.
- Battery Problems: For wireless keyboards, low battery levels often cause malfunctions.
Once you’ve identified a likely cause, you can focus on targeted solutions.
Check for Physical Damage:

Start by inspecting your keyboard for visible signs of damage. Here’s what to look for:
- Key Jams: Press each key individually to check for sticking or unresponsive keys.
- Spills or Debris: Turn the keyboard upside down and gently shake it to remove dirt or crumbs. Use a can of compressed air for stubborn debris.
Solution: Clean Your Keyboard
- Power off your Mac or keyboard before cleaning.
- Use a soft microfiber cloth and isopropyl alcohol to gently clean the surface and keys.
- Avoid harsh chemicals or excessive moisture.
Restart Your Mac:
Sometimes, the simplest fixes are the most effective. Restarting your Mac can resolve temporary software glitches causing the keyboard to malfunction.
How to Restart Your Mac:
- Click the Apple menu in the top-left corner of your screen.
- Select “Restart” and wait for your Mac to reboot.
Check if your keyboard works after the restart.
Update macOS:

- Click the lock icon and enter your admin password to make changes.

Troubleshoot Wireless Keyboards:

If you’re using a Bluetooth keyboard, connectivity issues are a common culprit. Here’s how to troubleshoot:
Check Bluetooth Settings
- Open “System Preferences” and select “Bluetooth.”
- Ensure Bluetooth is turned on.
- Check if your keyboard is listed as “Connected.” If not, reconnect it by selecting the keyboard and clicking “Connect.”
Replace or Recharge Batteries
- For keyboards with replaceable batteries, insert fresh ones.
- Recharge built-in batteries and ensure they’re fully charged.
Reset Your Keyboard’s Settings:
Resetting the keyboard settings can resolve software-related issues.

- Click on “Keyboard Settings” and reset to default settings.

- Release the keys after about 20 seconds.
Try an External Keyboard:
Testing an external keyboard helps determine if the issue is with your Mac or the keyboard itself. If the external keyboard works, your Mac’s built-in keyboard may need repair.
Reinstall macOS:

If all else fails, reinstalling macOS may be the solution. This step should only be taken as a last resort, as it’s time-consuming and requires backing up your data first.
Steps to Reinstall macOS:
- Restart your Mac and enter macOS Recovery by holding Command + R during startup.
