Macbook Track Pad Problems
Many of the problems encountered with a MacBook trackpad are often due to the buildup of dirt on the surface of the trackpad, or a problem with the trackpad settings. Because these common issues are the easiest to solve – and can be solved yourself – you should investigate these possibilities first when troubleshooting problems with the trackpad.

Trackpad Settings
-
The trackpad on a MacBook operates differently than trackpads on PC laptops. It is designed to be used for clicking, scrolling and swiping with one to four fingers at a time. If the trackpad is working, but you are not getting the results you require from it, click the “Trackpad” icon in System Preferences. You can review the settings there, watch accompanying videos and modify the settings as required.
Problems Caused From Lack of Grounding
-
The trackpad on a MacBook may become unresponsive when connected to an improperly grounded power adapter. If the trackpad has problems only when the power adapter is plugged in, the power adapter may be improperly grounded. Plug the power adapter into a three-pronged wall socket. If there are no three-pronged sockets available and you are using a two-pronged wall adapter, rest your hand on the palm rest while using the trackpad. This will ground it and allow the trackpad to work properly.

Cleaning Trackpad Surface
-
Dirt, dust, smoke or oil from your hands may cause problems for the trackpad. To keep the trackpad working properly, it should be cleaned from time to time. If the texture of the trackpad does not feel smooth, or feels uneven to the touch, it should be cleaned. Turn off the MacBook and use a soft, lint-free cloth to clean the trackpad. Do not spray the trackpad or let liquids get on it. Do not use abrasives or solvents to clean the surface of the trackpad.
Cleaning Inside Trackpad
-
Liquid, dust, crumbs or other debris under the trackpad button may cause it to work improperly. If you suspect this is the happened you should take the MacBook to an authorized technician. Trying to clean underneath the trackpad yourself may damage it further, or void your warranty. If you do decide to clean the underside of the trackpad, turn off the Macbook and unplug it from the power adapter. Remove the screws from the bottom of the case, then remove the battery. A can of compressed air held 6 inches from the trackpad may solve the problem.
