How to fix your Apple mouse when the scroll ball stops working
Anything from finger grease to dirt can make the scroll ball stop working, but here’s an easy fix straight from Apple product reviews. I just tried it and it works like a charm.
Grab yourself a little alcohol pad (the kind in a first aid kit). start with the mouse right side up and place the pad between your finger and the scroll ball and vigorously scroll in all directions. Then turn the mouse over and continue with a new pad or clean part of the previous one. Approx 15 seconds per side and your mouse scroll ball will work great again.
Alcohol swabs work fine. Also: wait for the ball to dry completely before using normally.
