Mighty mouse losing connection

I frequently suffer loss of connection of both the mouse and wireless keyboard. Sometimes the screen shows the usual lost connectivity symbols but not always. Batteries are NOT the issue. There are periods when the frequency is every few minutes and then days apart. The problem has been present with Tiger through to Snow Leopard. I am in danger of doing a Gordon Brown anytime soon.Can anyone help?

Add me to those who started having this problem after the 10.5.7 upgrade. I lose both the mouse and the keyboard about once or twice a day and the only way I can get it back is to open the MacBook and turn off Bluetooth and then turn it back on again.
I'm sure that true to Apple form, we'll hear no official replies here for something this insignificant, but one day there will be an update that mysteriously fixes this and we'll all forget about it. Happens all the time.

Mighty Mouse loses connection since 10.6.8 update

Hi I have recently installed the 10.6.8 OSX upgrade in preparations for the Lion release and I am having problems with Mighty Mouse losing connection.
Basically the mouse operates fine until the mouse is static whereby it loses connection, I then have to wiggle the mouse around and click the mouse to regain connectivity, if the mouse remains still for even a second it just drops again.
I have tried changing batteries, removing both my mouse and keyboard from the bluetooth preferences, adding them as favourites as well as doing the PRAM and SMC resets.
I only assume the problem is linked with 10.6.8 update because prior to this update the mouse was working without a hitch.
My keyboard appears to be working without the same problem.
Any suggestions?
Thanks

I encountered the same problem as you report after the upgrade to 10.6.8 on both my family's MacBook Pros. I had no problem with my MM up to that point. Thereafter, the MM would not work I went thru' the same steps as you did to try and overcome the problem. It pairs OK and says it is connected but the MM will not work. If you switch off the MM, a message is received "Connection Lost". The keypad mouse works as does an USB mouse, but no MM despite numerous attempts at resetting, clearing, replacing batteries, bluetooth reset, etc.. I am as baffled as you were and put the fault down to the SL upgrade, but I suppose the upgrade may (somehow) have blown the MM, but it still lights up and says it is connected!!. WEIRD!

Mighty Mouse Bluetooth Connectivity

Hi,
I have a wireless Mighty Mouse and a new MacBook. If I turn on my mighty mouse first, then turn on my MacBook, the mouse works fine, but if I forget to turn on my mighy mouse until after I have already turned on my MacBook, it will not connect automatically!!??
When I had a Windows PC, I had a wireless keyboard and mouse from Logitech. Even if I turned on my PC first, then turned on my mouse or keyboard, it would automatically start working, but now I am using my Mac, unless I turn on my mighty mouse first, my Mac will not find it. Why is this and is this normal??
I have just purchased a wireless Apple keyboard, I have not used it yet, but will the same thing happen with this also??
Please help. Thank you for all your help with this annoying matter.

Hi again Dai Bach,
Thanks for your help mate.
I was wondering, you use a wireless mighty mouse as well. I have now own 2 mighty mouse, my current wireless one and a wired one I had with my old Windows PC before I switched.
I am having great difficulty using the right click, which you are supposed to be able to do with the mighty mouse instead of control clicking to get the contextual menu up. If I do use the right click, it very rarely works, if it does work, I am amazed, but I can never repeat it!!!
I have to resort to control clicking with the mouse to get the contextual menu to appear, which sort of misses the point of having the mighty mouse in the first place!!! If this was the first time it had happened, I would say it was a problem with my mouse, but this is the second mighty mouse I have had and the same thing happened with my first one.
I tried changing the mouse settings to see if the mouse hardware works correctly. I went into the keyboard and mouse system preferences and switched the primary and secondary mouse buttons over so it was configured for a left handed person. The left click and right click actions then worked perfectly, but when I put the mouse back to the standard configuration, so the primary click was the left mouse button and the secondary cllick was the right, the right mouse button stopped working when I wanted to right click something!!
Why does the right click work when I have it set as the primary button, but not work when I have it set as the secondary button? Do you or anyone else have any ideas? Does this happen to you too? Is this a well known problem?
Cheers. Thanks for all your help.

Mouse losing connection

My mouse is losing connection with my computer on a regular basis, and regaining it after around 1-2 minutes. The problem is happening every day, sometimes up to 5 times, during which time the mouse is completely unresponsive. I've tried rebooting, turning the mouse on and off, changing the batteries but nothing seems to work. Can anyone help, as I've never had this problem with wireless mice before?

Hello:
Try resetting the PRAM and SMC. It is also possible that the mouse is failing.

Two Wireless Mighty Mice losing connection on two macs - what's going on?

I have a PowerMac G4/466 and a Power Mac G5 Dual 2GHz. Yesterday I bought two wireless apple keyboards and mighty mice, with D-Link BT dongles, for both computers. I have the same problem on both. Basically, the mice lose connections so frequently (actually, the connection is lost constantly) that I have had to go back to my wired mouse to get any kind of quality work time on my Macs. For some reason, when the wireless keyboard wasn't connected, the mighty mouse on the G4 worked fine (haven't tested this on the G5 yet). I have looked through a few of the topics in this forum and all I seem to find is other users who have the same problems but no answers. Can anyone give me a few pointers to try and sort this problem? I would like to use the wireless mighty mouse and for it not to be a waste of money buying.

It might be worth your while to view the iMovie tutorials at http://www.apple.com/ilife/tutorials/imovie/index.html because they can answer a lot of questions you may be having with your new computer.
If your iSight camera was on while you were trying to import video from your camera into iMovie, something was set wrong.

Simple "fix" to Mouse losing connection.

I was constantly losing connection between Mac Mini and my Mouse. Also battery drain was an issue. I left the battery cover off a few months ago off and have had no problems with connection since and still using same batteries (I used to have to change them weekly or biweekly).

Mighty Mouse looses connection with Mavericks ...

Hello,
last week I installed OSX 10.9 on my iMac i5 Mid. 2011 on a 2nd partition. At the 1st partition, I work with Snow Leopard.
Since a few days I noticed, that my Mighty Mouse looses the connection to the iMac more frequently when I work with Mavericks. The batteries are at 60% and they both fits very well.
If I reboot with OSX 10.6.8 Snow Leopard, I'm able to work for hours, the connection is stably all the time. The mouse don't lost the connection.
Has anyone an idea for this behavior?
Thanks
G. Hansen

Well, that rules out wi-fi interference. Some people have reported that their Wi-fi causes Bluetooth devices to drop intermittently.
I've got a Magic Mouse and it hasn't had any troubles with 10.9. My trackpad either and it's Bluetooth as well.
Hopefully someone else will have more insight.

Mighty Mouse loses connection randomly

Hey Apple Discussion Members,
I got a regular 24" iMac with bluetooth keyboard and mouse(had it for at least 9 months) ....
For the past 2 weeks, the mighty mouse randomly stops responding and shows on the screen "Connection Lost".
The battery level is 3/5(green)
Can anyone help? Thanks!

same here
turning off and on generally helps to get it reconnected. but happened at least 4 times this weekend.
i saw these errors in system.log

Wireless Mouse Losing Connection

Anyone else having this problem? It just cuts out and I get the picture on the screen saying "Connection Lost." It doesn't seem to matter what I'm doing. I have an new, extra bluetooth mouse (because I'm clumsy and have tile floors...) and that one won't work either. So, I resort to the wired mouse from my old computer. I've tried new batteries, too, even though there was no warning of them running out of power.
Any thoughts?

I usually turn my BT mouse off and flip it upside down so when the computer comes on next morning at 6, it's not paired.
This morning I turned it on, flipped it to working pose and it didn't pair quickly at all. With fresh batteries, it would work for only a few minutes, then lose its connection.
Over and over and over.
A full re-boot seems to have fixed it, but one is always suspicious after a software update comes in as happened yesterday with iMovie 9.0.2.

Magic mouse losing connection with thunderbolts jack plugged

the mouse loses its connection rigth away whenever the thunderbolt at the back of the iMac is plugged. anyone else having the same problem?

Hello Emma:
Making a BT device a favorite (or favourite ) is one of my standard suggestions for an occasional loss of connectivity.
Try trashing a preference file (com.apple.bluetooth.plist - found in the Macintosh HD), restart, and then make the device a favorite (add to favorite option).

Magic Mouse Losing Connection When Slightly Knocked

I've had this particular mouse for just over a year and in the last 2 weeks it's started to lose the connection when it's knocked however slightly on the table - for example when repositioning the mouse when moving something between 2 screens.
I've tried all the usual fixes, new batteries, different batteries, trashing the mouse preferences (as suggested here) and making the mouse a BT favourite, but as soon as it even remotely gets knocked, it disconnects.
Really frustrating, have gone back to a cable mouse for now but does anyone have any ideas? Is it a genuine fault I can get sorted under my warranty?

OK I spent A solid day playing with this and found that there are many correct"ish" answers here, but for the most part I have found that the physical tolerances of the Apple magic mouse have caused all of my problems.
THe info about plists and resetting pram are all kind of obvious choices and may work for many people becasue the mouse screws up in that way on occasion.
For the rest of us, check my earlier post about tolerances. THe battery end plate is one problem. The inserted card thing by Ken Evans is one piece of the puzzle. However for me the biggest piece of the puzzle is the tolerances of the battery plate cover in general.
The piece that fell into place a day ago ( a few hours afte my last post) is as follows:
Look closely at the plate on the bottom of the mouse - notice how thin it is. Notice how closely it touches the on off switch. Notice that if the plate is tweaked even a little bit it twiddles the on off swich breaking connection. Notice how you use the mouse a- do you lift it and put it down and perhaps press on the plate etc.
Notice if you press and push and drop mouse etc - anything that twiddles the plate will nail that switch.
For me I found that the plate was tweaked such that the middle of the plate pressed harder against the batteries than the ends did. This effectively "shortened" the length of the plate by a smidge which was just enough to constantly tweak the on off switch - ie put pressure on it with any major movements of the mouse - especially lifting it and putting it down when i ran to the end of my pad.
I re-tweaked the plate in the opposite direction ( not for the klutz- this plate will buckle faster than a teenager with a false id). if you feel handy you can tweak it by springing it lightly against a pencil but I am not buying anyone a new plate if you bend it. I also took a small swiss rat-tail file and filed out the switch hole a bit more - to make it a bit "longer" and hence not rub against the plate
Result is that i went from a lost connection about every minute to no lost connections for the last day. For me the resetting of the pram and dumping the plist file did not help - hence i looked further.

Magic Mouse losing connection and battery drains

I found a "fix" for both issues by removing the battery cover and leaving it off.....batteries stay put without issue, too.
I no longer have battery drain (it has been a few months using same alkaline batteries) and I do not lose my connection with my Mac Mini anymore.
Once in a while, when I first turn on my computer and mouse I have to tap on the batteries to get initial connection but that happens only a couple times a month. Compared to my previous frustration with connection issues and constant changing batteries....this simple "fix" has been wonderful.

Nothing fancy....I am using Duracel. The only times I have had to fiddle/tap a bit with batteries has been when I have moved mouse to new location.....(picked mouse up and plopped it down)...normally, I don't to do a thing with them. Certainly agree, the batteries are more exposed to dirt but my mouse is on a mousepad and in a clean dry area on my desk so not a problem to date.
It would be interesting if you or others try this and it works for everyone? If so, then the battery cover must have a design flaw. I am not going to try and figure it out as I a happy camper with my adjustment. Sure beats all the battery replacing and interruptions to connection I had previously. Good luck with your mouse!

Magic mouse losing connection

Hello
I have a problem with occasional loss of connection with my magic mouse. having read the threads already posted on this subject, I have tried to set up the mouse as a favourite within system preferences/bluetooth. however, i can't see how to set it as a favourite....i have clicked on the little gear sign and selected 'more info', which is then displayed, but i cannot change 'favourite...no' to yes.
i'm sure it's something simple i'm missing, but i just can't see how to change it!
cheers

Magic Mouse Losing Connection When Sleeping

My magic mouse loses its connection when my iMAC goes to sleep. I have the preferences setup to allow my iMAC to be awakened by bluetooth devices... Any suggestions?

Let me add, that this happens when the machine is asleep and all user are logged out... I have to use the wired key board to wake the machine up and then I can log in at the user log in prompt.

Wired mouse losing connection

I use an Evoluent wired mouse. In the past week (since last update?) the mouse has gone dead for no apparent reason, could be after a couple of minutes inactivity or longer. If I remove the usb plug and plugin again it works.
Any one come across this with wired a mouse?
This has happened three times today already, very annoying.

It could be just that the driver is incompatible with the update. Try going to the manufacturer's website for an update driver, or at least an acknowledgement that they're working on a solution.
