    Hello all,

    This has been a horribly annoying problem for over a month now, and Barry's solution is so far working for me. I agree the magic mouse is extremely buggy if not setup correctly. Come on, Apple.

    Also, I always work with my iphone and magic mouse next to each other, and have since turned Bluetooth off on my iphone to avoid any problems.

    Changing the batteries from rechargeable to 'normal' batteries fixed it for me. I made the mouse a favorite, too ... but that didn't help me, at least. I changed batteries and immediately it worked again. (without having to look for it). New batts and go!

    Thanks all, though, for the help!

    So far so good.

    Hey dudes,

    Just thought I'd add my solution:

    Basically I discovered the common denominator in all my connectivity issues was a slight jolt of the mouse, whether it was me even slightly lifting the mouse up and putting it back on the table, using the 'flicking' capabilities of the mouse etc. I jammed a bunch of blue-tac between the batteries and it seems to hold them in place firmly, I haven't had any problems since.

    I had the same issue - every time the mouse was lifted off the desk as I was using it, the jolt would cause a disconnection. I've wedged a little piece of paper between the batteries and haven't had the issue since.

    Problem are the positioning of the batteries! If they are not inserted correctly or shift a bit during transport, the connection gets lost. Just noticed it while reading the post, I had constant connection loss suddenly, opened up the mouse and saw that 1 battery was not exactly where it should be. Positioned it correctly and now my mouse is working as it should.

    Check it out!

    I moved the mouse to the left of my keyboard - further away from wall and electric plugs etc. and I have not lost the connection since (was losing it every five minutes or so before moving it). Tried jerking it in the left side and it didn't seem to make a difference - it stayed connected. When I put it back the other side - lost the connection almost immediately!

    I was having a problem with my MM as well. It was dropping the connection regularly, the pointer would stop mid screen whilst I was moving the mouse, it was difficult to accurately click on an action etc

    Tried all the fixes that have been suggested in this thread but no improvement.

    The guys at the local Apple store did some research and found that (on a MacPro at least) there is a problem with the aerial placement on the Bluetooth transmitter/receiver which affects the signal. They re-wired it using one of the wireless aerials (which apparently there are 2 of and more powerful or better positioned) and it works great now. It now responds from meters away and I haven't lost connection since then. Took them about 1/2 hour to do and they didn't even charge me. Thanks to the guys @ Forest Computers in Hope Island, Gold Coast Australia - they deserve a plug !!

    It hasn't affected connection to my Airport base station either although that is only about 3m away from the Macpro.

    I use a MM with a macbook pro on as a docked workstation setup. I also use the bluetooth keyboard. The magic mouse problem has been driving me in sane as it will constantly loose connection.
    The plist deletion made no difference
    It has always been a favorite so that makes no difference
    I turned off bluetooth on my iphone, no difference
    I thought it might be battery related, so I just today went and got the Apple rechargable batteries..mostly cause the specs were great..if they really last 10 years, and $30 for 6 batteries and a charger isn't too bad a price.
    Put the new, fully charged apple batteries in, connection drops still.

    I just put paper in the batter compartment as others had mentioned above in the time it took to write this post no dropping (as I knock on wood). I also notice on my mm that the batter cover seems a bit loose, so maybe this is the issue with mine.

    Just wanted to add my thoughts in on what might be working...if the connection drops again I'll post again. As a side note, the keyboard has never once dropped.

    I was having the same problem and the piece of paper in the battery compartment did the trick. For now I am convinced it's an issue with the battery not having the right contact on the "+" side. I love the MM but think this is a pretty sad engineering design problem. I would expect more from Apple.

    Okay, I have an update from my previous post...
    Nothing is helping with my connection issue...BUT I do believe I have found the issue, at least in my case:
    The power button on the bottom gets nudged off.
    Started immediately looking for the green light on the bottom when the connection dropped, and what I saw was that the power button is somehow sliding to the off position, sometimes just the smallest smidgen, but apparently just enough to interrupt the power. I will be trying some things to take care of it, possible a piece of tape over it?

    This is very frustrating indeed.

    I agree it's a physical not a logical problem. I put some rolled up Aluminium foil in the wee recesses where the + end of the battery fits and now it works fine.

    I posted earlier after having divined that the problem lay in the poor connection in the positive terminals. After a little more use—and a lot more drops—I just bit the bullet and bought some non-rechargeable 1.5V AAs, and now, a day later (4-5 hours of use) , I haven't had a single drop. For me, the issue is resolved: You MUST have 1.5V AAs, and not 1.2V.

    hi all
    this may sound stupid bcoz it is but i have to say anyways .....i put the batteries in the wrong way and the magic mouse still worked but kept losing connection....i never thought this could have happened .....usually one battery is opposite to the other and without paying enuff attention i put them in wrong ......STUPID i no..... both batteries have the + terminal at the top after doing this ive had no bother .........good luck .........

    Solved the problem. It's actually quite simple...

    After being TOTALLY FRUSTRATED with the INSANE amount of connection losses - I threw the Mighty Mouse onto the floor. It broke into pieces. Now it's not a problem anymore.

    Too bad I had to waste a costly device. But honestly I'm happier using the old Mighty Mouse once again - at least that mouse works.

    The reason for the recurring disconnections - mainly when it gets a slight jolt by lifting/putting it down on table or mouse-pad, is the weakness of the spring-loaded negative contact, especially when the opposite positive contacts are slightly oxidized.
    To solve the problem, spray a bit of electric contact-cleaner on a piece of white, soft paper and rub gently the four contacts, especially the slightly recessed positive ones.
