7 Ways to Fix ESC Key Not Working on Mac

The Escape key is a crucial component of macOS, enabling users to efficiently navigate and interact with their Macs. However, when this key stops working, it can significantly hinder productivity. Here are seven comprehensive ways to fix the ESC key not working on your Mac.

Determining the Cause of the Issue

Before diving into fixes, it's essential to determine whether the problem is hardware or software-related. This step will help you choose the most effective solution.

Use the Virtual Keyboard: To check if the issue is hardware-related, use the on-screen keyboard.
- Click the Apple icon in the menu bar, then choose “System Settings.”
- Open “Accessibility” from the left side of the window, then scroll down and click on “Keyboard” on the right.
- Turn the toggle on next to “Accessibility Keyboard.”
- On the on-screen keyboard, click on the ESC button. If it works, you likely have a hardware problem. If it doesn’t work, the issue is probably software-related.

1. Restart Your Mac

A simple restart can often resolve many software-related issues, including a non-functional ESC key.

Click the Apple logo in the menu bar and select “Restart.” Wait a few seconds and then try using the ESC key again. This can clear temporary software glitches that might be causing the problem.

2. Update macOS

Outdated macOS versions can contain bugs that interfere with keyboard functionality. Ensuring your macOS is up to date can fix many software-related issues.

Click the Apple logo in the menu bar, then choose “About This Mac.”
Click “Software Update” and wait for your Mac to check for updates.
If an update is available, click “Upgrade Now” and follow the prompts to install the update.

3. Disable or Force Quit Siri

Siri can sometimes interfere with the ESC key, especially if it gets stuck or shows errors.

Open System Preferences and choose “Siri.”
Uncheck “Enable Ask Siri” to disable Siri. Wait a few seconds and then enable it again if needed.
Alternatively, you can force quit Siri by opening Activity Monitor, searching for Siri, and clicking the “Terminate” button.

4. Start Your Mac in Safe Mode

Booting your Mac in Safe Mode can help identify and resolve software issues by disabling third-party applications that might be causing the problem.

Restart your Mac and immediately hold down the Shift key.
Release the Shift key when you see the login window. This will boot your Mac in Safe Mode.
Log in to your normal account and check if the ESC key works in Safe Mode.

5. Reset Your Mac's SMC

The System Management Controller (SMC) manages various system functions, including keyboard input. Resetting the SMC can sometimes resolve keyboard issues.

For MacBooks with a removable battery: Shut down your Mac, remove the battery, and press the power button for 5 seconds. Then, reinsert the battery and turn on your Mac.
For MacBooks with a non-removable battery: Shut down your Mac, locate the following keys: Power button, Command (⌘) + Option (⌥) + Shift (⇧) + Power button. Press and hold these keys while powering on your Mac. Release the keys when you hear the boot chime for the second time.

6. Log in to a New Account

Sometimes, user account settings or third-party applications can cause issues with the ESC key. Logging in to a new account can help determine if the problem is account-specific.

Create a new user account on your Mac.
Log in to the new account and check if the ESC key works. If it does, the issue might be related to your original account settings or applications.

7. Assign Escape Function to Another Key

If the ESC key is not working and you need a temporary solution, you can assign the ESC function to another key.

Click the Apple icon in the menu bar, then choose “System Settings.”
Open “Keyboard” from the left side of the window, and click on “Keyboard” on the right.
You can use the “Modifier Keys” option to remap keys, though this is more about adjusting modifier keys. For a more direct approach, consider using third-party software that allows key remapping.

Additional Tips

Run Maintenance Scripts: Using a utility like CleanMyMac X can help run maintenance scripts that may resolve system errors affecting the ESC key.
Check for Physical Damage: If the ESC key issue persists and you suspect hardware damage (e.g., from spills or drops), it may be necessary to visit an Apple repair center or authorized service provider.

By following these steps, you should be able to diagnose and fix the ESC key not working on your Mac, ensuring you can continue working efficiently.
