Hi everyone, So recently and seemingly randomly, my magic mouse has stopped tracking on my desk surface. It moves but jaggedly and only slightly. My desk has a semi shiny finish to it, and the magic mouse has always worked on it in the past. The weird thing is if i put it on a black surface it tracks fine... I have tried the following -Cleaning laser lens -Resetting pram etc -Resetting bluetooth settings -Different mac. I am confused to what it could be? any ideas?
