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.
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:
- com.apple.driver.AppleBluetoothMultitouch.trackpad.plist - Magic Trackpad
- com.apple.driver.AppleBluetoothMultitouch.mouse.plist - Magic Mouse
- com.apple.driver.AppleHIDMouse.plist - wired USB mouse
- com.apple.AppleMultitouchTrackpad.plist
- Com.apple.preference.trackpad.plist
4. Delete the files.
5. Reboot your MacBook.
After that you have to perform one more task.
Resetting Parameter RAM (PRAM) is similar to resetting the SMC in that it’s a good fix for a wide variety is issues.
- Fully shut down your MacBook.
- Reboot your MacBook and press and hold Command+Option+P+R before the gray screen appears.
- Wait until you hear the reboot sound and release the keys.
- Let the system reboot normally.
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.
- Restart your MacBook.
- When the system restarts, press Command+R to open the Recovery Tool.
- Select Restore From Time Machine Backup. This will restore your Mac back to 24 hours previous.
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.
