Apple mouse loses connection

My iMac's magic mouse persistently loses its bluetooth connection for intervals ranging from seconds to several minutes. This has been a problem since shortly after I got the Mac (2010), and I've replaced the mouse twice. It works for a while, and then the problem resurfaces. The last couple of days the mouse seems to go to sleep whenever the computer does and takes up to five minutes to reestablish its connection. The battery level is at 100%. There's nothing new on my desk that would cause interference. Any ideas?

I've read with interest this and various other threads on this problem. Over the past few months my Magic Mouse has been losing connections very frequently - it's not the batteries! Having plowed through various threads in this forum, there was a suggestion to delete some file /Macintosh HD/library/preferences/com.apple.bluetooth.plist. Alas, under Maverick (10.9.*), this file seems to be protected. However, I found another way to resolve the probelm:
Just remove the Mouse and let the Mac "find" the mouse again: System Preferences->Bluetooth to display the device. Click on the x next to the mouse. If you wait a few seconds after that, the Mac rediscovers the Mouse again. I haven't lost connections for several hours now, and that's a first!

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.

Magic mouse lose connection

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

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".

My Mac OS X 10.6.8 is wakes up slow, occasionally hangs, and my mouse loses connectivity fairly often.

Recently my Mac has been waking up very slow. It runs all applications slowly when I first start using it. It seems to be better after that. My mouse also loses connectivity several times a day, even with new batteries. Not sure if that is related. When I try to restart it Safari often won't close even when I force it.

I ran Etrecheck and this was the result.

Apple A1015 loses connection

I've had several of these mouses(mice) and though it is an older model, I consider it the best one. A common problem with these is that they lose connection easily with my Mac Pro. Is there a solution to this? I always shut down the mouse before changing batteries.

I just read through ten pages of another thread that discusses this same issue. Throughout the thread some have found fixes that work for them. Here is a summary of those fixes:
Fixes that have worked for some others:
-I should start by pointing you to this Apple Home Sharing Troubleshooting page:http://support.apple.com/kb/TS2972 This covers all basic things to doublecheck...same apple ID on all devices, etc. --If you have found this thread, you are smart enough to have things set up correctly. However, it does suggest adjusting firewall and network settings which have solved the problem for some (I will include those fixes below since they are actually helpful)
-Set AppleTV to never go to sleep. This can be done from the settings.
-Open ports in firewall settings for both computer and routers. Home Sharing uses TCP port 3689 and UDP port 5353 to communicate with shared iTunes libraries. Make sure they are open. A lot of people think this can't be the issue because they think the Apple TV wouldn't ever connect if it were a firewall issue. This is not necessarily the case, so don't overlook this suggestion.
-Set the IP address on routers extending the network. If you are using an Airport express or Airport extreme to extend a network created by a time capsule or other router, setting the IP addresses to fixed instead of auto-assigned via DHCP has worked for some.
-Make sure your Bojnour service is up to date on your computer. Here is more info on Bonjour Wake on demand

My Magic Mouse Loses Connection Every Single Minor Tap

My Magic Mouse tends to lose its connection whenever I give it a tap on the table. I mean, it's normal right, when you lift the mouse a little bit and tap it to the surface to give the pointer a little more distance like browsing the web or playing a computer game. My Magic Mouse seems to lose its connection everytime it gets a minor tap on the table and no, I don't slam it hard.
It's not a battery problem since I change them frequently so I'm guessing it's either the hardware problem or the Bluetooth problem. Any idea what's causing this?

Actually I believe it is a battery problem. Specifically, not all batteries are created equally and vary from brand to brand so with the tolerances as tight as they apparently are in (or are not) in the MM the positive terminal does not always make contact with the MM terminal.
Based on other posts in these forums the positive terminal varies slightly among brands. Some are higher than others. It's a minor amount but it appears to be enough.
I've seen this with my neighbor's MM. Brand new batteries (forget the brand at the moment) yet I could shake the MM and have it make and break contact. On the other hand I don't have the problem with my Sayno Eneloop rechargeables.
You might try inserting a small piece of paper or aluminum foil to take up the gap.
Another possibility is that the contacts are corroded so try to clean them a little.

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!

Mouse loses connection

I have a Mac Mini and a few months ago I started having problems with the Magic Mouse losing its connection to the computer. If I wait a few minutes it comes back but in one hour it may drop the mouse 3-4 times. I have used new batteries and even went to the extend of buying a new mouse thinking that it was my old mouse. But that wasn't the problem because this is even happening with the brand new mouse. What I notice first is that the mouse's responsiveness starts to change--it isn't as responsive. Then the next thing I see is "Connection Lost." I have gone into Utilities and have checked that the disk is OK and all my permissions are right. I was thinking of simply reinstalling the OS but would like to see if others have suggestions. Also, I don't know if this is related or not but I have a wireless printer that seems to work fine for a while and then it too will drop the connection and the printing will stop only to restart a while later. Suggestions?

I might have actually figured out the problem. Even re-installing the OS did not help. I still got printer errors and my mouse still moved real slow at times and would lose connectivity. So I hard-wired the printer to the network and turned off the WiFi on the printer. I still got "communication errors". Then I turned off WiFi on my Mini (it is hard wired to the network), uninstalled the printer, rebooted and reinstalled the printer (although I kept WiFi off for now). The mouse has worked perfectly well for over an hour and I have printed numerous documents with no problems. I will let this run for another day and if all is well I will turn WiFi back on on the printer. But for now it looks like running the WiFi on the Mini was causing the problem.
Thanks for the suggestions, Illaass. They helped getting me to think about conflicts. I do want to look at my router and see if I can set it to only run on the 5 GHz bandwidth and see if that helps. But I don't need WiFi on the Mini so if keeping it off solves my problem then I am happy.

Apple TV loses connection to internet and can't reconnect without restart

When I first purchased my ATV3 it had extremely slow buffering problems and then crashed. I had to do a full factory reset and software update. Then that problem went away. Recently it has a new problem. While renting a movie from itunes with the ATV connected to the internet via wireless (strong signal) from an airport extreme connected to my modem from cox communications (with about 30Mbps speed) it will suddenly stop and by stop I mean it leaves the movie completely and says YOUR APPLE TV IS NOT CONNECTED TO THE INTERNET.
So if I go to my network in the apple tv menu, sure enough my wireless network is missing. But the ipad is finding it, and the imac on wireless is finding it, and it is working. So we hit restart on the apple tv. When it comes back all is good. Then maybe the movie runs ten minutes and it does it again.
In some cases the wireless network reappears but if I select it it still says I'm not connected to the internet.
I have to restart everytime or it will not properly reconnect to the internet or find my wireless net work and actually work and connect.
From time to time it finds it and when I select it it asked me to log back in with password etc. So I do that, and then it says some error code (sorry didn't write that one down) and says try again later.
I have not tried hooking up my ethernet cable. Since my other devices all work while the apple tv is kicking me off, I don't believe it is a problem with our wireless network. And there are no buffering issues.
Anyone heard of this ?
Should I reset my factory settings? (I don't own the mini usb cable for the apple tv so connecting to a computer is not an immediate option)
Any suggestions are welcome.
Oh, and my original apple tv, the older model with the 160gb hard drive in it works fine. Just don't rent on it because of resolution of the older model.

Mine is doing the exact same problem!
Ever since I rented a movie from itunes with the ATV connected to the internet via wireless (strong signal) from an airport extreme connected to my modem from charter communications (with about 30Mbps speed) it will suddenly stop and by stop I mean it leaves the movie completely and says YOUR APPLE TV IS NOT CONNECTED TO THE INTERNET.

It has been connected in the same place for a year and never had an issue.
Nothing has changed..... I have not added a wall to cause interference....
My iPad and iPhone show FULL strength.
Please help!

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

Magic Mouse Loses Connection

My Magic Mouse keeps losing its connection. Has any one else had this happen to them. I reapplied the update and had gone through the set again but the connection repeatedly is lost. Luckily I still have my wired mouse plugged in or my IMAC would be useless.

I was having the same problem... getting a real mouse with a cord fixed the problem instantly... the magic mouse is without question the worst thing to come out of apple since the mighty mouse... the connection goes in and out all day long... probably spent 10 minutes out of every hour waiting for lost connections... when it does work, you feel as though you have to press twice as hard, and hold on for dear life to keep the mouse working... I see the might mouse like dating the best looking girl in college even though she's as dumb as a fence post... it takes a long time to get past her looks, but once you do and dump her for something good looking and brighter, your life is a thousand times better... the amount of trouble a dumb girlfriend or rotten mouse provides isn't worth hanging it... avoid the magic mouse at all costs... it's not worth the trouble... it should be noted i lost the connection TWICE writing this post...

Magic mouse loses connection with laptop unless laptop connected to charger

So, I've been seeing people have various problems with the Magic Mouse in Lion, but I haven't seen anyone with the exact problem as me. I lodged it as a bug with Apple, but I wondered if anyone has the same problem and maybe a solution.
I have an original MacBookAir and a Magic Mouse. Since upgrading to Lion, the Magic Mouse will only stay steadily connected to the laptop if I have the laptop plugged in and on the mains charger. If I am running the laptop on battery, the mouse disconnects and becomes unusable.

thv2011,
There are some known problems which other devices on the 2.4Ghz can affect. Here's the apple support article on the subject:

Apple TV loses connection to Library -after update to 10.6.1.7 - ideas?

After update this morning, i have returned to the old 5 mimutes of connection to library, and then connection dropped... Very annoying.Of course apple will blame Windows XP, or my router, or my firewall, etc. etc.. funny thing is, it worked perfectly until the update this morning... Any ideas other than port forwarding, windows firewall changes, etc. etc.? Any idea what Apple has done this time?
Cheers

TS2972 Apple tv loses connection with home share

Recently received an apple tv as a gift. I connect it to iTunes through home sharing but the connection is lost after only a few minutes.

Well I firured it out, but dont know why it did this. When I restarted my computer and then opened itunes back up. Itunes changed the location of my media to the default location. (I changed the location of my library to my external time machine since it was becomeing to large). Again not sure why it decided to do this all of a sudden but that was the problem

Apple TV loses connection after sleeping

My Apple TV had virtually no problems with a connection when being used, but has this curious quirk of losing it's connection after an extended sleep period. It seems as if it sleeps for more than 8 hours, it will no longer be connected to my network. Viewing the settings for the Apple TV, it shows that my connection should be working and has full strength, but doing a test results in nothing happening. My options are restart or drop connection and input my network password again. This gets really annnoying, because almost everytime I want to use it, I have to do either of those things first. Are there any internet settings I can chnage so that this stops happening?

Actually same goes for the iPhone after charging it when I sleep, next day, have to turn wifi on and off to get the connection to work properly.
