How to Fix Erratic Trackpad on Your Macbook Pro?

Share This:

If you're experiencing erratic trackpad behavior on your MacBook Pro, it can be frustrating. There are a few things you can do to troubleshoot and try to get it back in working order.

First off, if your Mac has a non-removable battery, hold down Ctrl + Option + Shift on the keyboard and then press and hold down the Power button for ten seconds. This should reset the SMC and get your trackpad working again.

Another possible cause of erratic behavior is an aging battery that has started to bulge under the trackpad, causing it to lift up. If this is the case, you may want to consider replacing your battery as soon as possible.

In some cases, the problem can be traced back to a missing or out-of-date driver for the touchpad. To fix this, open Device Manager by entering “Device Manager” in Search on the taskbar, then select Device Manager. From there you can update or reinstall your touchpad drivers which should help resolve any issues you may have been having.

Finally, if you recently suffered from a bad spill or have any suspicions of water damage inside your laptop, it's best to take it to an Apple store or authorized repair shop for further inspection and repair if needed.

We hope these tips help get your MacBook Pro's trackpad back in working order!

Fixing an Erratic Trackpad on a MacBook Pro

If your MacBook Pro's trackpad is behaving erratically, the first thing you should try is resetting the System Management Controller (SMC). This can be done by holding down Ctrl + Option + Shift on the keyboard and then pressing and holding down the Power button for ten seconds. After releasing the buttons, restart your MacBook Pro and see if this has resolved the issue.

If that doesn't work, you may need to open up your laptop and clean off any debris from inside or around the trackpad. If there are any visible signs of damage to the trackpad itself, it may need to be replaced. You can also try updating or reinstalling the drivers for your trackpad, as this might help resolve any issues that are causing it to behave erratically.

Troubleshooting a Spazzing Trackpad

It is possible that the trackpad spazzing out may be due to an aging battery. Over time, batteries can swell and cause pressure against the trackpad, making it lift up and behave erratically. Additionally, if you recently recovered from a spill, even if you cleaned the laptop's surface, there could be water damage inside the device causing the problem. To diagnose this issue further, please contact your laptop's manufacturer for assistance in replacing or repairing the battery or other internal components.

Troubleshooting Unusual Trackpad Behavior

It's possible that your trackpad is behaving strangely because you don't have the correct driver installed, or because the driver is out of date. To resolve this, open the Device Manager (by searching for it on the taskbar) and check to see if the touchpad driver is up-to-date. If it isn't, try reinstalling or updating it. If that doesn't work, you may need to contact your device manufacturer for assistance.

Recalibrating a Trackpad

To recalibrate your trackpad, you can perform a four-finger salute. First, press the upper-left corner of the keyboard and hold it down. Then press and hold the upper-right corner of the keyboard. Next, press and hold the lower-left corner of the keyboard, and finally, press and hold down the lower-right corner of the keyboard while keeping your fingers off the touchpad. Make sure you press down on all four corners at the same time and that you press down on the “fn” key last. This should reset your trackpad's calibration settings to their default values.

Impact of Viruses on Touchpads

Yes, a virus can affect your touchpad. The most common type of malware that causes problems related to the touchpad is Win32/Sality.AT. This virus is particularly dangerous because it deletes everything that comes in its way by turning them into shortcut files. It can even infect an external hard drive or USB and cause problems with your touchpad. To protect yourself from this type of virus, you should always make sure to update your software regularly and scan all incoming files before downloading them to your computer. Additionally, you should avoid clicking on suspicious links or opening unknown emails, as they could potentially contain malicious code that could infect your computer and compromise the functioning of your touchpad.

Troubleshooting Unwanted Touchpad Movement and Clicks

If your touchpad is moving and clicking on its own, it may be due to several different factors. First, it could be a hardware issue—there may be something wrong with the touchpad itself. Second, it could be a software issue—your laptop settings may have been accidentally changed, or you may have a driver that needs updating. Third, it could also be caused by too much dust or debris accumulating on the touchpad surface. To determine the cause of this problem, you should first check your laptop settings to make sure they are correct. Then, if needed, update your drivers and clean the touchpad surface to remove any dust or debris that might be interfering with proper operation.


In conclusion, if your Macbook Pro trackpad is behaving erratically, it could be caused by a variety of issues. It may be a result of aging batteries that are bulging under the trackpad, water damage from a spill, or an outdated or missing driver. If none of these solutions help, you may need to take your computer to an Apple Store or authorized repair center for further diagnosis and possible hardware replacement.
