Let’s Start with Few Practical Scenarios

Scenario 1: Desktop and Mouse Jerking, Moving on Their Own After El Capitan Update

Hi, I updated to El Capitan a few days ago and used it fine for a few days. Today when I got on my computer it seemed to have a mind of its own. It’s almost like someone is remotely controlling my computer. mouse jerks and moves around on its own, Desktops change on their own, view gets bigger and smaller on its own, I can sit in my chair with my hands in my lap and the screen and mouse move on their own. I can’t work. Does anyone know what the heck is going on? MacBook Pro retina, mid-2012, 2.7GHz i7,16 GB, 1600 mhzDDr3, El Capitan 10.11.3, Have an external view sonic monitor attached, Use an apple wireless keyboard and a Logitech mouse. Thanks!

Scenario 2: My Cursor is Moving by Itself

My cursor is cycling rapidly through both upper-level menus and dialog boxes by itself.  The problem resolves briefly when I restart and then recurs.  Do I have a virus?  Does anyone else have this problem?  Or a solution? Thanks!

Scenario 3: Pointer Gone Crazy on My MacBook Pro

Like the above two users, there are many Mac users who are facing erratic/jumping cursor issue on Mac. Let’s troubleshoot to fix it.

You may also like: 

Restart Your Mac

Most of the time simple restart fixes the issue. Click on Restart from the Apple Menu and check the cursor movement on the Mac.

Check for Any Damage to the Mouse or Trackpad.

Even small physical damage can result in erratic/jumping cursor issue, check for any damage to make sure that is not the problem. Also, make sure trackpad is fitted and aligned properly on the Mac.

Make Sure Mouse or Trackpad Battery is Charged

Ensure that the device’s batteries are not low. In case of Magic Trackpad 2 or Magic Mouse 2, ensure that the battery is fully charged.

Prevent accidental or Multiple Touch

Make sure that only required part of your finger is touching the touch surface. Accidental and multiple touches can cause unwanted cursor movement.

Keep Trackpad or Mouse Dry and Clean

Moisture, oil or lotion can cause unnecessary cursor movement so make sure that devices are moisture free and clean.

Avoid Using Third-Party Power Adaptor

Abnormal cursor behavior occurs when you use a third party power adaptor. Unplug the power adaptor in case you are using third-party power adaptor and check if the cursor is abnormal. In case, cursor behaves normally while running the system with battery only, replace the power adaptor.

Scan for Virus, Malware, and Adware

Virus, malware, Adware or spyware may be responsible for abnormal cursor movement. Visit this link and run free MALWAREBYTES FOR MAC to check your Mac and do the needful. You can scan your Mac for the virus in case you have anti-virus software for Mac.
