1 Initial Check

Begin by cleaning your keyboard gently. Dust and debris can often cause keys to stick or not register. Turn off your MacBook and hold it at a 75-degree angle, using compressed air to blow across the keys in a left-to-right motion. It's important not to spray liquid or air directly under the keys, as this could cause damage. After cleaning, test each key to see if the issue persists.

2 Software Update

Software glitches can sometimes cause keyboard malfunctions. Check if your MacBook is running the latest operating system (OS) and if any updates are pending. To do this, click on the Apple logo in the top-left corner of your screen and select "About This Mac." Click "Software Update" to see if there are any updates available. Install any that are needed and check if the keyboard's performance improves.

3 Reset PRAM/NVRAM

Your MacBook's Parameter RAM (PRAM) and Non-Volatile RAM (NVRAM) store certain settings which can affect keyboard functionality. To reset them, shut down your MacBook and turn it on while holding down the Command, Option, P, and R keys simultaneously. Release the keys after about 20 seconds or once you hear the startup sound for a second time. This reset may resolve keyboard issues.

4 SMC Reset

The System Management Controller (SMC) is responsible for many low-level functions on your MacBook, including keyboard management. Resetting the SMC can often resolve hardware-related issues. To reset, shut down your MacBook and plug in the power adapter. Hold down the Shift, Control, Option keys, and the power button simultaneously for 10 seconds, then release and turn on your MacBook to see if the keyboard issue is resolved.

5 Test User Account

Sometimes, keyboard problems are specific to a user account due to corrupt files or settings. Create a new user account by going to System Preferences > Users & Groups, clicking the lock icon, entering your password, and then clicking the "+" to add a new user. Log into the new account and test the keyboard. If it works fine here, the issue might be with your original user account settings.

6 External Keyboard

As a final step, try using an external USB or Bluetooth keyboard with your MacBook. If the external keyboard works without any issues, the problem likely lies with the hardware of your MacBook's built-in keyboard. In this case, professional repair or replacement might be necessary. This test helps determine whether the issue is software or hardware-related.
