Magic Mouse: Bluetooth Connection Lost

Periodically (and extremely frustrating) my iMac screen will announce "Bluetooth connection lost".
There seems to be no logical explanation. But...
This leaves me with a totally functionless Magic Mouse.
Is there a way of re-establishing Magic Mouse/Bluetooth without going through the hassle of connecting a USB mouse to reach System Preferences?

I'm starting to have problems with the Bluetooth not recognizing the Magic Mouse even though 1) it's discoverable and 2) I favorited it. Does this have anything to do with the new Magic Prefs app?
One other thing that could make a major difference is that I downloaded USB Overdrive in order to use a Logitech joystick. It really should have no bearing on something that is not a USB device, though that preference panel does recognize the Magic Mouse...in spirit if not in function. I cannot scroll with it or use the touch-specific functions of that device. If Bluetooth cannot read it, what good is it anyway?

Magic Mouse Bluetooth Connection - WiFi Interference

I have a macbook and recently purchased a magic mouse. It constantly connects and disconnects. I replaced the batteries, re-paired th BT connection, no luck. I spent an hour on the phone with apple support and we tried everything they had in their database, no success. I then took it to the genius bar at the local store with the same result. Apple replaced the mouse with a new one, having the same problem. The mouse only has issues in my apartment. When I go to the conference room on the 1st floor, the mouse works fine. I suspect my time capsule wifi 2.4ghz is causing interference with the bluetooth. I tried to disable the 2.4ghz wifi and only use 5ghz, but I can't find a way to do it.
If anyone has any ideas, I would be grateful.

Magic Mouse Bluetooth connection problems with Mac OS X Lion

I've a problem with my Magic Mouse on bluetooth since I've updated my Mac to Lion, it's disconnecting too often. How to fix it ?

It might be a physical battery connection problem. The solution was already described by this article:http://macs.about.com/od/tipstricks/qt/Fix-Magic-Mouse-Disconnects.htm
Placing a trimmed piece on paper that was cut from a business card between the batteries and the battery-enclosure lid helps hold the batteries down firmly. This eliminates the tiny freeplay that allows a physical battery terminal disconnect when the mouse is jolted.

Magic Mouse loosing Connection

My magic mouse looses connection with my iMac every few minuites to every few hours. I have tried replacing the bateries several time. The only way to make it reconnect is to put the computer to sleep and wake it back up a few times. What can I do to stop this?

Greetings, I had the same problem after the original batteries "died". New batteries 100% charged after 1-2 min mouse lost connection. Tried Setup of bluetooth mouse many times + new batteries - same result.
Tried removal of com.apple.Bluetooth.plist - no difference.
On all my batteries there are a date/manufacturing code stamped in ink under the negative pole . I removed the ink - scraped away with a screwdriver and installed the batteries again. The Magic Mouse is now connected all the time. This challenge took 3 hrs to solve - hope it will save someone some frustration.

Magic mouse wont connect boot camp 4.0

I have just installed a fresh copy of OS X Lion with Boot Camp 4.0 on a new iMac. I have been unable to get the magic mouse to connect via bluetooth. I have uninstalled and reinstalled the driver with the same result. I can see it when I add devices but connection never completes.
Any advice?

I figured this one out. =)
right click the mouse in the add menu... then click properties. check the box in the menu that appears. click apply. connection should complete there-after.

Magic mouse lose connection

my magic mouse lose (bluetooth) connection no and then. It reconneccts in a minute or so.
What's wrong?
Regards
/Stefan

There's already a thread on this with almost the same title:
Magic Mouse Loses Connection
One idea (discussed in that thread) is that not all batteries are created equal in that the positive terminal varies in size among different brands and "flatter" ones are not making contact all the time. One solution was to add a little ball of aluminum foil between the negative size (I assume) to take up the "slack".

Magic mouse sudden connection loss

My magic mouse loses connection suddenly. I have tried even changing batteries but the problem is not resolved. Please help

Look at the threads in More Like This at the right.
One general theory is that different makes of batteries have slightly different length positive terminals and loose connection. Some find adding a small shim of aluminum foil to keep the batteries from moving works. Others just a piece of paper to push down and serve the same purpose.
Others sometimes have problems with interferance.

Magic Mouse drops connection with two blinks; unable to reconnect

My magic mouse drops connection frequently. It may drop connection at any time with no reason and goes off into two blinks. Then it's unable to be reconnected. I've tried many things, including turning the mouse off and on, turning Bluetooth off and on, unpairing the mouse and try to repair (unable to discover at this moment), but nothing works. After waiting for a long time it may get connected suddenly.
I believe it is the computer's issue rather than the mouse. I have two Macs (MacBook Pro and iMac) and two Magic Mice, but the issue only happen to my MacBook Pro with either of the two mice.
Any suggestion would be appreciated. Thank you!

I really cannot see why those problems relate to only one of your machines though you don't say if you have reset the SMC on the MacBook Pro. See ...
http://support.apple.com/en-us/HT201295
Nor do you say if you have given the batteries a thorough check. While this should not affect only one machine, Try removing them, clean the inside of the compartment and the battery terminals themselves. If it is reasonably possible, replace the old batteries with new ones.

My magic mouse loses connection during sleep

My Magic mouse loses connection during sleep mode. I also get error message my external usb storage drive was disconnected improperly. I have to unplug and plug in drive generally, sometimes it is still present. For the mouse I generally turn it off and on and allow it to be found again.

This is a late 2009 imac.

My magic mouse loose connection

hi, my magic mouse loose connection every time i lift it up!
i have a late 13 imac with all upgrades on.
also new batteries on it ,not rechargeable.
any idea?

Sounds to me they are loose inside the compartment. There are two possible causes. A badly made mouse (very unlikely) or inferior quality batteries. We generally find Apple, Energiser or Eneloop are the recommended ones; others, especially minor brands, can be that tiny bit too short and leave them liable to movement.

Connect other bluetooth device to mac once magic mouse is connected

Hi all,
First of all, I would like to apologize if a thread already covers this issue.
I am planning on getting a Magic Mouse. I understand that it pairs with the mac via blue tooth. My question is, will I still be able to pair another blue tooth device (phone) to my mac once the magic mouse is already connected.
Has anyone tried this?
Thanks in advance!

You can pair up multiple bluetooth devices at the same time, such as the Magic Mouse and a cell phone, no problem. My mouse can get a bit jerky while I transfer files, but that's the only problem I've seen.

Magic trackpad bluetooth Connected / Connection Lost

Hi there,
I have a Mac Pro 2010 (Not macbook pro). I use a magic trackpad alongside a wacom intuos.
My trackpad has been displaying connected / connection lost for quite some time now and its rather annoying.
This doesn't happen after sleep, not does it take 60s to kick in (like some reports I've seen). It starts immediately and continues forever.
I check back on these forums periodically to see if anyone has had my exact problem and no dice.
Here is what I have tried:
• Reboot
• Reset PRAM
• Reset SMC by disconnecting power cable from tower
• Replacing batteries, changing battery brand
• Checking connectors for signs of corrosion on batteries and in the trackpad. (they're clean)
• Running trackpad a friend's macbook air (it worked and maintained connection)
• Running on another laptop on the same desk as the Mac Pro (maintained connection – ruled out local interference)
It seems to have been since Yosemite, but not instantaneously. I am loath to reinstall the OS and quite frankly have seen that this has not been a step towards fixing it for anyone!
Any new fixes anyone has, I'd love to hear them! Also my trackpad is personalised. Can i reset it? Perhaps that would fix it!
Thanks

To uninstall Chrome was no problem because if you reinstall it you lose nothing, unlike with some apps.
But this link with Yosemite seems to go on and on and no-one has come up with an answer. I don't think Bluetooth is the fault but it may be connected (forgive the pun) to a service or app you have. As I said, I have neither Yosemite or Chrome so I can only offer educated guesswork rather than practical help.
This would not be a solution but if you could download and apply Etrecheck, it may show something in your system. This link should take you there. Then copy / paste it here in this thread.
