Magic Mouse tracking poorly and losing Bluetooth connectivity since Mountain Lion upgrade

Yea, it's not Flash nor is it CPU usage, at least not exclusively. It was happening to me with all browsers closed and only 2% cpu usage (sparrow). It's happening now with Chrome open and only this page loaded.

This is extremely frustrating. It is really slowing down my work and the closest Apple store is an hour and a half drive away.

I've done what others have suggested by changing WiFi (802.11) channels on my Airport and it seems to have resolved the issue. I still get the occasional Magic Mouse disconnect, but not the jittery mouse.

In this thread:

David suggests restarting in Safe-Mode. (Shut down, press power key, hold down SHIFT immediately after the start up tone until the Apple symbol appears)

I had already tried the suggestions made by Apollo2000 here:

https://discussions.apple.com/thread/4167078?start=0&tstart=0

With some success.

Restarting in Safe-Mode restored the functionality of the USB hub built into my 30" Appple Display and resolved the Magic Mouse bluetooth connectivity for me. The effect continued over beyond a standard restart.

So:

Safe-Mode boot

then Restart

I hope this helps.

OK, so I have an early 2011 MacBook Pro, and the problem for me is that about once every week or two, my magic mouse starts slowing down, exhibits jerky movements, and this gets progressively worse for about a minute or two. Then the "Connection Lost" ghost warning pops up, followed within seconds by the "Mouse Connected" ghost pop-up. Then all is well for another week or two. The keyboard works fine, never exhibits this behavior. This is usually solved by replacement of the batteries. Since this just happened, I see my Eneloop batteries are at 15%, so I will replace.

Hello

Ok, so I have read all posts about this and it seems there is no solution right?

You buy a "magic mouse", that is quite beautiful, and expensive, but it does not work, right? Or, it works but not consistently.

Thx

I actually love the mouse, and the small inconvenience (I almost typed incontinence) is worth it to me. Just keep fresh batteries in it and change them when it starts acting up.

The BlueTooth connectivity problem returned last week after I posted a solution a while back. I performed a Mac OS X 10.8.2 Combo Update and everything has worked okay since then. This issue seems to come and go, but this solution seems to work best.

Ha ha! I laugh because this sounded like such a great possibility and I figured it could not hurt anything! I applied the Combo Update and the very first thing that happened after the restart was that the mouse lost connectivity. I did get the connection back really quickly, though! (Please note, I am not laughing at you, tjwaido, but rather at the absurdity of this whole situation.)

same problem here:

bluetooth mighty mouse worked perfectly before upgrade to mountain lion.

now frequent disconnects with freezing of blued (bluetooth service) in activation panel.

> can't even kill and restart bluetooth.

means complete restart!

Same problem here. Both bluetooth keyboard and mouse jitters and slows down. Turn off/On fixes problem for a while. Have not had this problem before I got the latest firmware-update for cinema 27".

Will try safe-boot - restart. Very annoying. Luckily only happens a few times a day. But everytime you need to open macbook and turn bluetooth off/on, and then close - this messes up all the windows.

I'm experiencing this problem and it's driving me crazy. Changing the channel on my router didn't help, nor did deleting and adding the bluetooth devices back. I have the same problem with both my Magic Mouse and Magic Trackpad.

Has anyone else found a solution? I was hoping 10.8.2 would fix it but it didn't.

I've given up trying all these methods. It may or may not be a software issue, and if it is, who knows when Apple will ever acknowledge the issue and/or fix it. Like others here, I have a 2009 MP and my issue started after Mountain Lion.

I've resorted to disconnecting the internal antenna and attaching a makeshift external antenna as documented here: http://nobblynoel.wordpress.com/2010/04/25/mac-pro-2009-bluetooth-fix/

The best reason to go this route rather than using a BT dongle is compatibility with the system/OS. Here's a link to that fix, which I tried and waking from sleep was an issue: http://oliverwolfson.com/apple-mac-pro-bluetooth-issue-solved/

The external fix took about 20 minutes and seems to have solved the weak signal. The parts are all available through Amazon...

Thanks for your reply. In my case, I do not have the issue with my Mac Pro, but I do have it with my MacBook Pro. It's hard to believe it has anything to do with reception. The trackpad and mouse are literally 6-12 inches away.

Has anyone else found a solution to this? It's making it nearly impossible to use my computer.
