Bluetooth Mouse Drop Out

My bluetooth mighty mouse keeps dropping signal. My batteries are fine but it keeps doing it every couple minutes. Anyone have this problem in the past and figure out what it was?

Me too. Started months ago, only once in a awhile, but now it is every half hour or so. I have to keep disconnecting in the Bluetooth drop-down, and then reconnecting. Major pain in butt. Apple said to install latest Bluetooth update. That fixed it for a day or more but now it's back on a regular basis. Apple said to call back when it's happening so they can diagnose, so I will do that if I am able to at that moment (most of the time I can't stop working, have to just keep re-connecting).

Keep in mind that Bluetooth runs on the same 2.4GHz frequency as many other devices. So, if you have a cordless phone base, a baby monitor or any other wireless device (including routers) near the machine, be sure to move those away. Additionally, microwave ovens are well known to cause this kind of interference (even if it's in another, adjacent room).

Mouse dropout

My mouse and keyboard drop out too. I've noticed that just opening the bluetooth preferences panel brings them back.

I haven't tried calling Apple--any luck there?

Are you up to date on Software Updates? Just recently, a major update came out for Bluetooth on OS X.
