For some it’s the MacBook keyboard that’s not working, for others, it’s the trackpad that’s acting up. For a worrying number of people, the issue is with both. Worse still, the problem doesn’t seem to be affecting a particular type of MacBook but both Pro and Air models from 2011 onwards.
I have passwords. No guest accounts. No other accounts but mine. The only thing missing might be file encryption, but I have my Mac set up with encryption. Why this is an issue for Windows 10 but not for Windows 8.1, I do not know. At least, I can have my Gmail account working on the Mail app, so I can try out the Mail app and see what I think.

Whether it’s one key or all of them, if the keyboard isn’t working, your MacBook is all but useless. Here are a few things you can try to kick it back into life.
That’s right. Cleaning is actually Apple’s recommended fix for unresponsive keyboards. To make this work you’ll need a can of compressed air and a straw to control the airflow. If you have those things, here are Apple’s suggested steps:
At the very least, using compressed air rules out any crumbs or bits of debris being the cause of the Apple keyboard not working. Hopefully, though, it provides the fix you’ve been searching for.
Is your system up-to-date? It seems obvious, but there’s every chance that outdated firmware, drivers, or even the operating system, is affecting the keyboard.
To check for updates, open the App Store and click on the Updates icon. If updates are available, click on the Update or Update All button to install them.
It’s worth having your MacBook check for updates automatically. You can do this by going to System Preferences > App Store and checking the “Automatically check for updates” box.
Is the problem a recent one? Has it occurred only after downloading a new app? It’s not unheard of for app to cause conflict and knock other things out of sync. Try deleting recent apps to see if the keyboard regains proper function. If it’s doesn’t work you can easily reinstall them.
You can delete applications manually in one of two ways: using the Launchpad and the Finder.
Removing apps manually is quick and easy, but it’s not comprehensive. Traces of the app can be left behind in files. To fully remove any trace of the app, CleanMyMac X’s Uninstaller feature is the best solution.
It really is as simple as it sounds.
The trackpad on MacBook is one of the best around and it works brilliantly with macOS… When it actually is working, that is. If you’re having trackpad troubles, work your way through these possible fixes.
This one is a bit of a strange tip, but it’s worked for a few people. It’s basically the old “switch it off and back on again” fix that works for anything and everything.
This tip might also work for the keyboard so if your keys aren’t working give it a try.
If a failure to register clicks is the problem for the trackpad not working on your Mac, you can disable Force Click.
Note: this fix will only work on MacBooks that include 3D Touch.
Resetting the System Management Controller (SMC) is a proven fix for all manner of hardware and power-related issues. How you do this depends on whether or not your MacBook has a detachable battery.

If both the keyboard and trackpad are not working, your MacBook is nothing more than a monitor, albeit a very pretty one. You can use a Bluetooth or wireless mouse or keyboard, but if you wanted to do that you could have just bought an iMac instead.
Here are some troubleshooting tips that have worked for dual keyboard and trackpad issues
Property List (plist) files are used to store user preference files related to software. Deleting them will reset your keyboard and trackpad back to factory settings. Before you go ahead and do this, you should backup your Mac using the Time Machine in case anything goes wrong.
1. Press Command+Shift+G in the Finder.
2. Enter ~/Library/Preferences/ and click Go.
3. Locate the following files:
4. Delete the files.

5. Reboot your MacBook.
Resetting Parameter RAM (PRAM) is similar to resetting the SMC in that it’s a good fix for a wide variety is issues.
If problems with the keyboard and trackpad have recently appeared you can restore your Mac to a previous date using the Time Machine. The issue could be due to a recent system change and a restore can repair it.
This method will require you to have Time Machine set up to backup data to a storage device. We’ve written an article on how to do that here.
Each of these fixes have worked for one or more MacBook users, so it’s worth trying each one until you find the solution. Once you’ve found a fix, use CleanMyMac regularly to maintain your system and prevent junk files affecting keyboard and trackpad performance.
If none of that works, your Mac will need a more comprehensive checkup. This is possible if you own a tool like MacPilot. Basically, it’s an uncomplicated version of Terminal that allows you to dive under the hood of your macOS. Using the app on a regular basis is also a good way to prevent your keyboard and trackpad from misbehaving in the first place.
MacPilot covers 1,200+ features — all of them accessible from one handy window. Whether you use the app for macOS activity monitoring or to investigate keyboard and trackpad issues, you’ll appreciate the help:
In case you want a simpler version of a monitoring tool, use One Switch. It’s a set of toggles available from the menu bar. Works perfectly for searching hidden files, enabling Sleep Time or Dark Mode, etc.
If the unthinkable happens and you’re still experiencing issues, you might need to contact Apple Support or visit an authorized service provider for repairs — but hopefully, that’s not the case.
Make sure your device's batteries aren't low. If you're using Magic Trackpad 2 or Magic Mouse 2, make sure its rechargeable battery is fully charged.
Be sure only one part of your finger is touching the touch surface and that you're not resting your wrist on or very close to the surface. The touch surface might interpret this as your finger touching it and move the pointer in that direction.
Moisture collecting on the touch surface can also cause this issue. Wiping off the surface of the trackpad or mouse with a cloth or tissue usually fixes this.
If the issue goes away when you put a piece of paper between your finger and the touch surface, consider purchasing a Teflon applique to fit over the surface to prevent moisture from having direct contact with the touch surface. Before you install the Teflon applique, make sure the touch surface is clean and dry.
Note that oil or lotion can also cause the same issue. You can clean your device's touch surface with a lint-free cloth lightly moistened with water.
Jewelry might also cause interference when you use a device with a touch surface. Try removing rings or bracelets and see whether the jumpy or erratic behavior disappears.
This behavior might happen if you use a power adapter made by a third-party company.
If you're using one of these power adapters, unplug it and try running your Mac from battery power to see whether the pointer behaves correctly. If the device behaves normally while running from the battery, there might be an issue with your power adapter.
Bluetooth devices can act erratically when there's wireless interference. See Wi-Fi and Bluetooth: Potential sources of wireless interference for more information.
If none of the above resolves the issue, you can start in Safe Mode to rule out third-party software as a cause.
