Command Key Not Working on Mac

When the Command key stops working on your Mac, restart your device, update macOS to eliminate any known bugs, and check for any malware. Then, navigate to System Settings > Keyboard > Modifier Keys to verify that your keyboard settings are correct. If you’re using an external keyboard, make sure both the cable and port are functioning properly. For Intel-based Macs, resetting the NVRAM and SMC can also help resolve persistent issues.

Why is my Command key not working on Mac?

Your Mac’s Command key might have stopped working after a change in your keyboard layout. For external keyboards, issues such as Bluetooth connectivity problems, a depleted battery, or a faulty cable or port are also common causes. In rare circumstances, malware or physical damage from debris, liquid spills, or impact may be to blame.

How to fix Command key not working on Mac?

Is your Mac’s Command key not working? Before giving up, try restarting your Mac and updating macOS. If you’re using an Intel-based Mac, manually reset the NVRAM and SMC, which help manage hardware and software functions. Next, we recommend reviewing your device’s modifier keys and adjusting your keyboard settings as needed. For external keyboards, double-check both wireless and physical connections. Lastly, consider the possibility of malware and follow the recommended steps to detect and remove it.

2. Check Modifier keys

The Command key is a modifier key that changes the function of another key when both are pressed simultaneously. While Apple provides default behaviors for modifier keys, you have the flexibility to customize their settings to suit your preferences.

If you think your keyboard mapping may have changed unexpectedly, use our tips to check and adjust the settings of your modifier keys:

1. Click the Apple logo in the menu bar.
2. Select System Settings from the dropdown menu.
3. In the left sidebar, scroll down and choose Keyboard.
4. On your right, click the Keyboard Shortcuts button.
5. In the new window, go to Modifier Keys.
6. Next, make sure Command is assigned to the Command key.
7. Click Done to confirm.

3. Check keyboard settings

While our previous tip helps you identify conflicts with the Command key, a more practical and user-friendly way to check your keyboard layout is to use the Keyboard Viewer. This tool lets you see what happens when you press the Command key.

Here’s how to use the Keyboard Viewer on your Mac:

1. Click the Apple logo in the menu bar.
2. Select System Settings.
3. Scroll down and choose Keyboard.

1. Click the Apple logo in the menu bar.
2. Select System Settings from the dropdown menu.
3. In the left sidebar, click General.
4. Click Software Update.
5. Then, click Upgrade Now.

5. Use external or USB keyboard

Keyboard not working on Mac? If your Command key isn’t responding, the problem could be with your MacBook’s built-in keyboard. To determine whether the issue is hardware-related, try connecting an external keyboard via cable or Bluetooth and see if the Command key functions properly.

If you’re already using an external keyboard, use these tips to rule out a faulty Command key:

• For wireless keyboards, disconnect and reconnect Bluetooth to refresh the connection.
• For wired keyboards, unplug and replug the cable, try a different port, or blow gently into the port to remove dust and debris.
• Clean your keyboard with a lint-free cloth lightly dampened with water or alcohol.
• Double-check that your keyboard is compatible with your Mac/MacBook model.

6. Check for malware

If your Command key suddenly stops working without explanation, unfortunately, malware may be to blame. We strongly suggest you protect your Mac by scanning for threats and removing any infections using trusted cybersecurity software like MacKeeper’s Antivirus.

Here’s how to check for malware on Mac with MacKeeper:

1. Launch MacKepper.
2. Select Antivirus from the sidebar.
3. Click Start Scan.
4. After the scan is done, select the detected malware.
5. Move it to quarantine.

7. Reset PRAM/NVRAM and SMC

Our final recommendation is specifically for users with Intel-based Macs: resetting the PRAM/NVRAM and SMC. If you own a Mac with Apple Silicon, you can skip this step, as these components are automatically refreshed during a standard restart.

We suggest you start by resetting the PRAM/NVRAM, which controls key software and hardware settings. Here’s how to reset PRAM on Mac:

1. Click the Apple logo in the menu bar.
2. Select Shut Down.
3. Press the Power button to turn your Mac back on.
4. Immediately press and hold Command + Option + P + R.
5. After 20 seconds, release all keys.

After that, follow these instructions to reset the SMC, which can often resolve keyboard and connection issues.

1. Click the Apple icon in the menu bar.
2. Select Shut Down.
3. Press and hold the Shift + Option + Control keys.
4. While holding the three keys, press and hold the Power button.
5. Release all keys after 10 seconds.
6. Then, press the Power button again.
