Wireless Mighty Mouse jumps around?!

Hi there!
I have an quite annoying issue with my wireless mm:
Sometimes it lets the cursor jump around and it is almost impossible to control it.
I am pretty sure it does not have to do with dust on the lens or shiny surfaces, because for 2 weeks it worked without any worries in the same environment. I almost believed the problem was gone.
Most of the time I manage to solve the problem by switching the mouse on&off for a couple of times and/or reinitializing the bluetooth connection.
Then it usually works for a while. But next time i wake my MacBook it starts all over again!!
Does anyone know this problem?
Thanks for any help!

I too am having this problem. I bought the mouse about two months ago and the day I synced it with my iMac it started freaking out too. I tried all the usual things, i.e. cleaned it, tried different mouse pads, tuned down tracking, resync it, everything. It just didn't work, but then I went on a trip and decided, "What the heck, I'll take the mouse and try fixing it on my MacBook Air." I get to my destination and resync it with the Air and it works perfectly, so I figured my desktop was the problem. I get home a few days latter after having used the mouse flawlessly and try it again in my house, when suddenly, it begins to jump around my MacBook Air. So I turned off the Bluetooth on my iMac (only a few feet from me and the Air) and the problem went away... for about 30 minutes, then my mother got on her iMac in her room, one room away, and lo- the problem did recur!
I believe the problem has something to do with the fact that the Mighty Mouse and the Wireless Keyboard both use the entire gamete of frequencies the Bluetooth has, thus, it is trying to sync with anything with Bluetooth in it, cellphones, PS3's, ext... Because if I take one of my MacBook's out into my ranch, far from anything, including my iPhone, the Mighty Mouse works! But the second I bring something with Bluetooth in range of the mouse, BAM! CRAZY MOUSE TIME!
I have dug around the Bluetooth shell inside OS X and found you can limit which bandwidths your computer receives, but this solves nothing if it is the mouse itself trying to sync with every computer and phone within range. I doubt this is how Apple intended the thing to work but they may have assumed that it was only meant as a traveling mouse, or perhaps to be used by people with only one Mac?
Perhaps there is a firmware patch out there that might solve this? I have seen ones for OS 9 and below, but nothing about OS X

Wired Mighty Mouse vs. Wireless Mighty Mouse

Hey, my wired Mighty Mouse track ball just crapped out on me (I can't scroll down anymore) so I guess I am looking to buy another one.
Does anyone have any experience and/or opinions on the Wireless Mighty Mouse track balls being any more reliable or longer-lasting than the Wired Mighty Mouse track balls? Or are they both pretty much the same quality-wise?
Many thanks.

Trust me, copelander, a mighty mouse that will not scroll in one direction is almost always simply dirty. I have two (one BT one wired) each of which I bought very soon after they first came out. Essentially failure to scroll in one direction means that one of the four directional sensors that it relies on has got clogged.
Cheby (above) describes the usual solution very well. Simply disconnect the mouse, hold it upside down, and rub the ball vigorously in all directions on a clean piece of paper. Try to avoid "running over" any of the tiny black specs that will probably appear on the paper , as the ball is good at picking them up again.
If things have progressed beyond the this, the tip of something like the plastic toothpick that comes with swiss army knives, or a cable tie, worked gently in around the edge of the ball, can help, but be gentle so you don't damage the mechanism. Some people also use a dab of isopropyl alcohol on a clean cloth applied to the ball.
To keep your MM running smoothly for a long period, clean it using the "rubbing on paper" trick AS SOON AS you get the slightest sign of bad scrolling, or every few days, whichever comes sooner. Once you have done this for a while you will find that the problem becomes much less frequent, as the internals get rid of any accumalated residual gunk.
People who smoke, and those whose hands get oily or grubby for one reason or another, seem to have more problems with this issue, and might want to think about a regular 'wheel" mouse instead, but I've found that a minute of preventative maintenance every few days keeps my MM's scrolling beautifully in all directions. I haven't noticed any difference in the behaviour of the wireless or wired models in this respect. They both use the same scroll ball mechanism, so this isn't surprising.
As far as choosing between a wired and a wireless one goes for use with an MBP the wired one is lighter, and probably uses less battery than having bluetooth running all the time. On the other hand, the BT one can be handy if you are working in cramped quarters, and don't want a jumble of wire to deal with.

Odd Wireless Mighty Mouse behavior with new Mac Pro?

Hi,
I have a brand new Mac pro and Wireless Apple Mighty Mouse & Keyboard.
The mouse however is not operating properly, it is jerky and slow to respond on a intermittent regular basis. I can move the cursor around the screen but it will stutter and jerk slowly then pick up ok?
I had the mouse and keyboard with my iMac and it worked fine. I have run all updates and re-installed but to no avail. The keyboard is fine.
I suspect it's a hardware issue with my new mac Pro but i'd love it if someone has any other possible causes.
Thanks.

Hi, there's a quite a few people with similar problems, including myself.
My keyboard likes to drop it's connection for no apparent reason, which in turn likes to mess up my mouse and cause it to stutter for a while. Pairing up new devices can do this too, I've found.
It's been thought that some Mac Pro's came with their WiFi and BT wires incorrectly fitted, if you have a search you should find a link to the tutorial if you want to try switching them around.
That said, it didn't make any difference to my BT keyboard and wireless Mighty Mouse, so I switched them back.
I've been hoping for a software fix, but no joy so far, glad I got a three year warranty as standard.

Wireless Mighty Mouse won't work properly with MacBook/tech support stumped

Hi. First post. Anyone heard of this problem? Appears to be location-sensitive. Problem described below, but first, short background...
Just bought entire Mac system after decades in corporate world with PC. Believed the TV ads that it would be simple. Already have been back to Mac store 6 times and have spent roughly 7 hours on phone with help line. Mac store even replaced Macbook entirely in case it was faulty logic board/Bluetooth circuit -- didn't help. Also, problem doesn't happen in store. So, to get to the point:
Wireless Mighty Mouse doesn't work properly when hooked up to Macbook -- herky-jerky, slow, unresponsive, sluggish, imprecise, intermittently better/worse. Went through a few Mighty Mouses and finally gave up; now using hardwire mouse and there's no problem. But before I return Mighty Mouse for refund, would like to see if there's a solution b/c I'd prefer wireless.
System is the latest little souped-up Macbook, 23" HD Cinema external monitor, external wireless Apple keyboard (which works fine), wireless Mighty Mouse (the culprit), Airport Express, HP printer. All brand new from local Mac store (Fifth Avenue, New York)... where the Genius counter folks have given up. I'm not convinced they believe me because (a) the problem doesn't occur there, and (b) after a couple of new Mighty Mouses, they finally just gave me a new Macbook to make me go away... but after going through the whole system setup once again, same problem. Have tried many different mousepads, BTW.
Tried all the stuff phone tech support suggested -- removing/installing/reinstalling software, etc. Airport works fine; using modem and printer connections there. Bluetooth works fine with keyboard. I've scouted around for intefering devices; even unplugged electrostatic loudspeakers and old tubed amps in living room (concrete wall separates rooms), unplugged hifi in same room, etc. On 40th floor of Manhattan hi-rise; concrete walls between neighbors. Have never had interference before with anything; previous PC system worked fine with Microsoft wireless (optical) mouse.
This is no longer urgent because hardwired Apple mouse works well. It's just mysterious.
Any thoughts?
Other than that, I like the Mac environment so far. Fifth Avenue store is cool, also, because it's open 24/7.

Hey, thanks! That was fast. I'm impressed by the Mac community.
This program helped my hardwired mouse, actually, and did give me wider parameters on the wireless mouse, but it didn't correct the herky-jerky/sluggishness -- actually amplified those problems.

Mysterious moving wireless mighty mouse...

I've noticed that my wireless mighty mouse, although sitting quietly on the desk, appears to be moving the onscreen pointer around the screen. This has been interfering with my use of TextExpander which I use to expand text snippets, so suggests that there's something wrong with the way the wireless mighty mouse is responding to being at rest. I've gone over to using a wired mighty mouse and don't see this behaviour. Anyone else getting this?
Should I just give the mouse to my cat? Or should I phone Apple?

Try taking the battery out of the mouse and putting them back in. Also, make sure nothing is blocking the LED.
Are you able to use your iMac with a regular wired mouse? In other words, if you use another mouse, does it function normally?
Otherwise (if the above is not helpful), it seems likely that the mouse is defective. You should take it back (or to an Apple Store) for replacement under warranty.

Did Wireless Mighty Mouse come with an installation CD?

I love my wireless mighty mouse that I bought with my imac but I want to use it with my newly purchased macbook as well. The only problem is, I can't seem to locate the installation CD that I'm assuming came with it.
The mouse DID come with a CD, correct? Is there anywhere else I can look - drivers embedded in Tiger OSX?
I've called Apple a couple times (on hold as I "speak"). Anyway, they haven't been able to help me too much, I spent 45 minutes last night and I just had to hang up with them and I couldn't get any answers. I will pay for it but I think maybe they're trying to see if they have any available CD's (I would imagine they should have some extras lying around :)!)
Thanks for your help.

You don't need the CD that comes with the Mighty Mouse. All you need to do is go to software update on the Apple menu icon and update your software. If there is any software for the mouse that needs updating, it will update.

Wireless mighty mouse and Log In/Out

I have been having some issues with my wireless mighty mouse under Leopard. I have noticed that if I am logged in under one account and log out the mouse no longer will move on the screen. The "Right Click" functionality if available but the movement is not. I also have seen this behavior when logging out of an account and then logging into another account. I have tried disconnecting the mouse and then reconnecting it but that does not seem to solve the problem. The only work around is to log out using the keyboard and then log back in. I was wondering if anyone else has had any similar problems or knows of any solution to this.
Thanks

I have noticed that if you log in/out with the mouse then I do not have the problem. But If I use the keyboard shortcuts to log in/out then the issue occurs. Possible bug?

Wireless Mighty Mouse interference under Leopard

Hi.
I recently upgraded to Leopard and I'm experiencing interference with my Wireless Mighty Mouse since: the cursor starts jumping erratically. The thing is - this only happens when I'm doing *Java debugging in my Eclipse IDE*. For the rest of the time, it works pretty much OK (may still jitter on occasion).
I'm using TimeCapsule in 2.4 GHz, this caused some problems before I changed the default channel. I powered it down completely and I'm still getting the same interference. This is not due to heavy CPU load - in other cases of heavy CPU usage the mouse works fine. I also tried switching to a wired MS mouse or using the TrackPad and it works OK.
Any clues?
Thanks,
Zviki

Thanks to the good people in java-dev mailing list, I found that it's spindump causing the slow-down. When the application hits a breakpoint it becomes non-responsive. The system decides it's time to activate spindump to dump the process information, in order to "report the problem".
This is totally wrong behavior. Spindump eats the CPU, making the mouse unresponsive.

Connect Wireless Mighty Mouse to windows xp pro sp2 on bootcamp

I recently installed windows xp pro sp2 on bootcamp i tried to hook up my Wireless Mighty Mouse and I got basically nowhere. I was able to get the computer to recognize it and i typed in the passkey "0000" and it knows that it is a bluetooth device and I changed the settings of the bluetooth to "always" be discoverable and still I have hit a dead end. I can still not seem to connect the wireless mouse in any way. What do I do???

I FUIGURED IT OUT!!! omg im so happy right now. For anyone who might be wondering I'll tell you how to make it work it you had the same problem. Once you establish the mouse a device, highlight it in the devices menu, then click properties, then services, and once it is done searching check the box for the driver and click apply and your mouse should work.

Does Time Machine Backup irritate wireless Mighty Mouse?

Hi there. I'm having a strange issue here. With an iMac that came with bluetooth mouse and keyboard, OS out of the box (no software updates installed because there's no internet connection), each time Time Machine is backuping files, the Mighty Mouse is acting weird. It actually feels like someone else is working with it. Even if I do not use it and leave it alone, the pointer goes wild on the screen. Trying to work during Time Machine backups is impossible, because I cannot use the Mouse properly.
Does anyone of you have a similar, if not, the same issue? Any ideas?
Thanks in advance,
later, Stephan

I am having a similar problem with my IMac and Time Machine. During wireless Time Machine backups, the wireless mighty mouse and wireless keyboard disconnect. If the mighty mouse remains connected, it moves very slowly and is virtually unusable.
So far I've thought of two potential problems to troubleshoot:
1. I experience this problem when I connect to the Time Machine through the "802.11n (802.11b/g compatible)" wireless connection (set in the AirPort Utility), but I don't experience the same problem when I connect to the Time Machine through a wired ethernet connection. So it appears the b/g compatible setting is causing interference. I haven't tested to see if the "802.11n only" wireless connections causes this problem or not.
2. I also wonder if the IMac does not have enough RAM to complete the wireless backup. My IMac has 2gigs of RAM, and during backups it maxes out. I plan to upgrade to 4 gigs to see if the problem continues. (Stephan, how much RAM to you have installed?)
peace,
Marcus

Wireless Mighty Mouse Sputters During Network activity

Has anyone figured this one out yet.
I have a wireless mighty mouse that when you copy files to or from a computer off a network,
it sputters and barely moves when trying to use it. If i plug in a usb mouse there is no problem at all.
Was using a verizon wireless router and just bought an airport extreme. Guess what. Still does it. When I hard wire my computer to the router all works fine.
I just cant think of what this could possibly be. Any help would be appreciated.
Thanks.

There are a lot of people with this problem - mostly MacBook owners, but probably because they're more likely to have the wireless and BlueTooth running.
I have the problem with a Logitech mouse on a Mac Mini -- cursor goes bonkers at random intervals, with terrible mouse lag, and I basically can't use the mouse when it's happening. It doesn't correlate with anything I can see in the Activity Monitor, but I can stop it if I turn off BOTH Airport and the router.
Not likely to be RF interference with the signals, IMO, but some have reported that switching to an 802.11n router (or 802.11g with b compatibility disabled) solved the problem.

Bluetooth headset disconnects wireless Mighty Mouse

I have a Jabra bluetooth pair of headphones (BT620S) that I use with my Intel iMac. They work great as headphones since they are connecting via A2DP. But they also have the option of being used as a headset, for example with softphones or similar. Only this is useless!
Every time I connect as a headset, my mouse disconnects and the sound result I get is really bad. It's like an inch thick concrete wall is between the headset and the computer, even though I'm sitting immediately in front of it?!
Any ideas? I've tried to unpair and pair both devices again. I also have a wireless Apple keyboard. Thanks!

Wireless Mighty Mouse unresponsive during Bluetooth connection to K800i

Whenever I use Bluetooth to sync my Sony Ericsson K800i with my Mac, I notice that my Wireless Mighty Mouse sometimes becomes slow and unresponsive. I have to switch the mouse off and on again, after switching off Bluetooth on the phone, for the mouse to go back to normal.
I am using a third-party plugin to provide iSync support for this phone, but I don't know if that would make a difference. I never had this issue with my K750i.
Any suggestions would be very welcome!
iMac Core 2 Duo 20" Mac OS X (10.4.8)

The combo update rolls up all the patches Apple has released since 10.5 hit the shelves into one monster download; so you don't need to have installed 10.5.3 to install 10.5.4 - you can go from any version. Some users swear that applying the combo update makes for a more reliable Mac, and it fixed my Mac problem.
But beware the combo is over 1/2 Gb in size and will take a good while to download, even on a DSL connection. You can find it on the Apple downloads page at:
http://www.apple.com/downloads/macosx/apple/
There are separate versions for the regular version of MacOS X and the more specialised server edition, so make sure you download the correct version (most people just need the file named Mac OS X 10.5.4 Combo Update).
Once you've got the update, close any applications you are running (remembering to save your data), double-click the update to start and follow the instructions. You will have to restart your machine at the end of the installation and rebooting may take a little longer than normal - this only happens the first time you restart your machine. Hopefully you'll be back in business as soon as you see the login prompt.
HTH.
Mike.

Wireless Mighty Mouse has stopped selecting, cutting or pasting

My batteries ran out two days ago. I changed the batteries but since then my wireless Mighty Mouse will not select text, cut or paste. It has other erratic behavior. Any help and advice welcomed.

Wireless Mighty Mouse has "loose" top shell

Has anyone else observed/been annoyed by the "looseness" of the top shell on the Wireless Mighty Mouse? I've noticed that the top shell has a definite "give" to it that preceeds the intended click of the mouse. This results in an audible "click" as you hear the plastic top shell come into contact with the base of the mouse, as well as a physical "give" that throws off the whole clicking motion and otherwise makes this $70 mouse seem like a cheap plastic toy... I posted a video (ironically filmed using my built-in isight) of the whole thing. It's the first time I've posted a video online so make me feel competent and take a look and see if this is what you're suffering from. If there is a serious issue with this, maybe we could take this info back to apple...
The video of this can be found here:
