This guide will discuss things that would happen resulting in a MacBook Keyboard and Trackpad Not Working. We’d also discuss a few possible fixes you’d want to explore.

MacBook Keyboard and Trackpad Not Working? Working Fixes You Should Try

Here are some fixes you can try should you find your MacBook Keyboard and Trackpad Not Working:

Fix 1: Check for updates

Most of the minor operation issues we encounter on personal computers are often because we don’t update the computer’s system software.

Similarly, running an outdated system software can cause your MacBook to malfunction. Check if there are new updates for your system and install them.

You can follow the process below to install a macOS update:

  • STEP 1: Go to “Apple menu
  • STEP 2: Choose “About This Mac
  • STEP 3: Go to the “Overview” section and click on “Software Update
  • STEP 4: If there are available updates, click on “Update Now

Fix 2: Clean your keyboard

Dust and dirt can disturb how well your keyboard functions, so cleaning it can help fix the issues that make it unresponsive.

Even Apple recommends that you clean your keyboard if it stops being responsive. Here are the steps Apple suggests you follow when you want to clean your keyboard:

  • STEP 1: Hold your MacBook at a 75-degree angle
  • STEP 2: Spray compressed air on the keys in a left-to-right and top to bottom motion
  • STEP 3: Rotate your Macbook to the right side and respray the keys while maintaining the 75-degree angle

Fix 3: Delete recent apps

If your keyboard and mouse stopped working after downloading an app, try deleting the app. If you are unsure if it is an app interfering with your keyboard, you can quit all running apps.

Just click the “Quit All” button in the menu bar. If your keyboard starts working again, then you should consider deleting apps you downloaded recently.

To view your most recent apps:

  • STEP 1: Go to “Finder
  • STEP 2: Click on “Applications
  • STEP 3: Click on “Sort By
  • STEP 4: Select “Date Added

Proceed to delete the app(s).

Fix 4: Reset the SMC

At times, you just need to reset your System Management Controller to fix the problem you have with your keyboard and trackpad.

Below is a guide on how to reset the SMC.

If your Macbook has a non-removable battery, follow this process:

Fix 5: Delete .plist files

.plist list files (Property List) store software-related user preference files. They contain some files that ensure that the keyboard and mouse function properly.

If some of your software settings relating to the .plist files changes, it can affect the working condition of your mouse and keyboard. In such cases, deleting the existing .plist files can help reset your keyboard and trackpad back to factory settings.
