Having issues losing connection with your Apple Magic Mouse? Well I was having that very same issue then started searching for possible solutions. My Magic Mouse was not staying connect to both my MacBook Pro & my wife’s MacBook Air. My Apple Wireless Keyboard was working just fine so this led me to believe that there was an issue with the mouse hardware. I searched on the web to find a few articles on the Apple discussion board about the batteries not always fitting correctly. Well with spring loaded connections I found that hard to believe. I did take out the batteries to play around with them. But the LED was always blinking showing that it found not find a connection. Or it would connect, then disconnect 1-5 sec later. The computer had enough time to register that the batteries were at 100% power.
Then I found one other blog about bluetooth interference from other devices. My iPhone 4s & my wife’s iPhone 5 were in the other room. I did not think there was a chance this this was the cause. But for the process on illumination I turned off the bluetooth from both phones, and ding. The Apple Wireless Mouse works perfect again. Thinking back I only turned on the bluetooth because of our new cars having bluetooth. I’ll have to keep turing it off when I want to use my wireless mouse (I’m not using a different mouse).
In conclusion if you have bluetooth enables on your phone it may interfere with your Magic Mouse. Your Apple Wireless Keyboard & Apple Wireless Toutchpad will not be affected. The devise are running of a similar frequency causing interference. Apple? Why didn’t you think of this? I guess my mouse is not as magical as I had hoped. But I still love it.
