Wireless Mighty Mouse Tracking Problem

I'm finding that sometimes my mighty mouse is not tracking downwards.
During these blips it will still tracking left / right and upwards.
When this happens, I can feel that the 'wheel' is not engaging the internal mechanism that drives the scrolling / tracking. After sometime of operation the mouse starts tracking again and I can physically 'feel' that the 'wheel' is engaging the internal mechanism.
Does anyone know if this is a common problem, does hte mouse need to be cleaned inside? Do I need a new one??

Wired vs wireless Mighty Mouse tracking

Has anyone else found that the wireless Mighty Mouse has different tracking or acceleration compared to the wired version? It feels as if it has some acceleration applied that I can't dial out using USB Overdrive, or that it has a slight dead zone or something when making very slow or small movements.

Yes I did install the software. I'm pretty sure I'm only using one finger. I can't see any perceptible difference between the way I'm using the wired and the wireless versions. Maybe the wired version is less sensitive. Also there is big difference in the weight of the two. The wireless is heavier (due to the batteries I imagine) and the wired seems downright feather light compared to it.
But thanks for the feedback

Wireless Mighty Mouse/Bluetooth problems

Good day to you all, ladies and gents!
Right, well I have attempted some research on this and it seems that there's quite a few other people that have issues with the Wireless (not so) Mighty Mouse.
Mine keeps cutting out. Basically just clicking and moving it around like a mad hatter reconnects it in a matter of 5 seconds, but it's getting really bad, and I've had this iMac for well over a year, I've only really been noticing it in the last 3/4 months or so...
The upgrade to 10.5.7 didn't sort it out either...
I don't use my bluetooth for much else, just transferring photos from my phone, and that works fine... My Apple remote seems to work fine too..
Sorry if there's already a forum dedicated to this issue, if there is I couldn't find one an I'm a noob!
Thanks!

Hi and Welcome to Apple Discussions ...
How to Clean a Mighty Mouse
Minimize Bluetooth Interference
(I have to keep my TV remote more than 3ft away from my wireless MM, other wise is disables the mouse and TV remote isn't Bluetooth)
Check System Preferences/Keyboard&Mouse and click Bluetooth.
Sometimes just re-pairing the mouse can help

Mighty Mouse Tracking Problems with Mac mini core duo

I have a new Mac mini core duo (2GB RAM, 100GB HDD) and I'm having problems with my USB Might Mouse.
The cursor stutters and doesn't track with the movement of the mouse and it will sometimes leap to a different part of the screen or get stuck at the last place it rested. At other times the mouse will track smoothly for a while before starting to stutter again. The behavior isn't consistent.
Is anybody else having tracking problems?
Any thoughts on what might be causing this behavior?
iMac G5 20 & Mac mini 1.42Ghz, PB G4 1.67Mhz, Mac mini core duo Mac OS X (10.4.6)

Hmm, this could be one of two things. Your mac might be faulty (Harware wise) which would suck. But, hopefully it is a problem with your drivers that need updating. Try these 3 options.
1. Update you mouse driver.
2. Update you video card driver (Video cards can sometimes affect mouse sensitivety -don't ask why)
3. This is my last solution, before consulting a technician (For money if you can do it free talk to one!) or returning your mini: Try reformating/reinstalling Max OSX and if u have bootcamp check out wat happens to the mouse in XP check for the same problem if it doesn't happen in XP your hardware is safe. IF the problem continues after this... looks like your hardware is bad in that case i recomend a return or send back (If your on warranty).
GOod luck,

Anyway to speed up wireless mighty mouse tracking??

i finally made the plunge and added a WMM to my dual G5 2.5MHz. I love the wireless part and will likely add the keyboard later. The biggest problem I'm having is that tracking is slow. Not jumpy like other folks are experiencing, just slow. I've got the older 23" Cinema HD monitor and I prefer a large movement of the pointer to a small input of the mouse. I've got the tracking speed maxed out on the control panel. Any way to make it faster? thanks.

Thank you very much for your help - it is exactly as you describe:
A login / logout is needed for the changes to take effect (and I'm embarrassed I didn't think of that myself!), and then any subsequent changes in the Keyboard/Mouse pref pane overwrite this, so you have to re-edit the plist and logout and back in again.
Many thanks!
EDIT: I wanted to mark this as "solved", but can't. I'm guessing its cos I didn't ask the original question...

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.
Cheers

Windows 7 and Wireless Mighty Mouse, Wireless Keyboard and sound problem

Hi,
I just installed Windows 7 x64 Ultimate on my iMac 24" white ( OS X Leopard 10.5 ). Surprisingly, it installed without any problems. The only problems I have now are the Wireless Mighty Mouse and the Wireless Keyboard ( alu ).
After I installed Windows I inserted the Leopard Instal DVD and installed Boot Camp. I got a message right away saying that: "This program has known compatibility issues...". I clicked Run program and continued. Soon I got the same warning, but this time not for Boot Camp, but Intel Chipset Device Software. I clicked Run program yet again and it continued installing. Then I got a different warning: "Service KeyAgent' failed to start. Verify that you have sufficient privileges to start system services." I clicked Ignore and installation continued. I got another "Service Mac HAL' failed to start. Verify that you have sufficient privileges to start system services." warning, clicked Ignore again and after that it finished soon and I restarted the computer.
When I came back into Windows there was no Apple folder anywhere or any sign that I have just installed Boot Camp ( should there be? )
I installed Boot Camp Update 2.1 for Windows XP ( because Vista x64 version wouldn't start ) and basically I got the same warnings I did when I installed Boot Camp from the Leopard DVD ( described above ). I also tried to instal Boot Camp Update 2.2 for Windows, but it didn't start. I also downloaded Bluetooth Update 1.0, but all I got was a message saying: "This update is not intended for this computer and will not be installed.".
There is also no sound.
This is basically it, I really hope some of you who run Windows 7 with wireless keyboards and mice can help me, because I desperately need this to work ( I use a Windows only program for school ).
PS. I have a 2007 iMac 24" white and while it is not on the we're-not-supporting-that list for the infamous Windows 7 Boot Camp update, all other iMacs from its generation are. Any ideas?

Found a solution for the "Boot Camp x64 is unsupported on this computer model" message. Here is the link: http://www.techulous.com/hardware/how-to-apple-boot-camp-64-bit-for-windows-7-on -unsupported-macs.html
Everything works ( for ) now. Yay!

Mighty Mouse tracking issue while downloading files

Hi everybody ...
I'm the owner of the Wireless Mighty Mouse... For about 2 months I'm recognizing a strange behavior.
When I do start a download via Safari (I'm connected to the Internet via Wifi 54Mbits (2,4 GHz)) the mouse tracking start to bucking. During the download no fluent motion occurs. After the download finished the bucking stops and the tracking flows seamlessly. Does anyone have the same problem? I'm not quite sure what the exact problem is but could this behavior result from the connectivity frequency of bluetooth and wifi? And please don't tell me to reset my keyboard or my mouse. I already did that. I also updated to the latest official software update for bluetooth.
Please help me.
Thx destinationCloud

Hi,
I have the same problem, but mine usually shows up when I have MS Word opened for a while. It is as if there is some other process cycling that interferes with the tracking. Sometimes it shows up as a major lag (cursor stutters and moves a little bit for a large hand motion) or the cursor jumps way across the screen. It isn't always when MS Word is opened, but more frequent when it is (occasionally with Pages too). Changing batteries doesn't help, changing surfaces doesn't help. After some time, the problem resolves and mouse moves smoothly again, for a while. This has been more of a problem in the last few months than before.... was the Bluetooth driver changed? Does it have anything to do with a cache that is used before changes are saved?
Where is the Bug Report link... I can never find it. Just put it right on the Support page please, BIG.

Wireless keyboard and Wireless Mighty Mouse failure

Hello,
I have just bought an iMac 20" with a wireless keyboard and wireless mighty mouse.
Both the keyboard and mouse will not work properly.
I followed the installation/setup instructions and paired first the keyboard and then mouse. Then the problems started.
1. Mighty Mouse tracking is dreadful and very slow (even after adjusting mouse properties)
2. Keyboard started to drop connection and then when awoke started repeating keys (as if key stuck)
3. Keyboard then disconnected and will not be recognised when searching for Bluetooth devices nor can I pair it again.
4. When both were working the Airport extreme wireless network would be lost (but I think that this is a red-herring and irrelevant)
Interesting once keyboard stopped working the wireless mouse tracking improved.
The only software I have installed since taking the iMac out of the box are (in order)
- Running/installing all Apple updates (including firmware 1.1)
- Installing Firefox 2.0
- Installing Adobe Reader 8.0
- Installing Stuffit Reader 11.0
- Installing Canon Bubble Jet Printer driver
- Installing latest version of Skype
If I use a USB mouse or keyboard they work ok.
This is the second replace imac within 2 weeks. The first had the same problem.
Can anybody help please as I'm new to Mac's after switching from a PC and I do not want to have to chuck either the keyboard or mouse or have the pain of Apple supplying me with a 3rd replacement iMac

Welcome to the Apple Discussions. Congrats on the new Mac.
Did you Repair Disk Permissions after the software updates and installs?
Whether this solves this issue for you, it is something that you should always do. Go to Apps/Ut5ilities/Disk Utility and select your OS X HDD. Press Repair Permissions. Run Repair Permissions until no more repairs are reported.

Issues with Bluetooth/Wireless Mighty Mouse since Snow Leopard Install

Hi,
I am having issues with my bluetooth wireless mighty mouse. It was fine after initially having installed Snow Leopard. However, in the past week it has become progressively more and more unresponsive. It functions perfectly normal for the first while after startup, then after a short period of time it becomes slow to respond to the mouse movements that move the cursor. Eventually it gets to the point that moving the mouse results in no cursor movement whatsoever. It also becomes unresponsive to squeezing the side buttons. There are no issues with clicking or scrolling with the track ball.
I have searched the discussion forums to find issues that pertain to "bluetooth" and "wireless mighty mouse" and have tried the following suggested remedies... Repairing my Mouse with my Mac mini. Renaming my mouse. Deleting the com.apple.Bluetooth.plist file from Macintosh HD\Library\Preferences and restarting my Mac. Reset PRAM and NVRAM. Also tried to install Bluetooth Firmware update 2.0.1 but I get an indication that the update is not needed on my Mac mini. I have also checked for software updates but there are none...
I am going to attempt resetting the SMC but am doubtful that this will help...
Can anyone help... Please... ?
Thanks,
Des

I had read in another forum where someone had an understanding that the bluetooth problem had something to do with Airport/Time Capsule. I had also read about how someone was having an issue with being unable to turn off airport. (I had this same problem.)
Upon deleting a few airport related plist files (see below url) I was able to turn off/on airport AND my Mouse issue has no longer appeared... everything is working a-ok now.

Mouse Tracking Problem -- Follow Up

Back in December I reported a solution to the problem of a wireless Mighty Mouse not tracking properly. I said that I solved the problem by "turning off my wireless" and "turning it back on again". PeteMac followed up saying (understandably) that he didn't know what I intended by the term "wireless". Of course, I never went back to the thread so I missed his question. I meant my MacBookPro's internal Airport. Simply turn Airport off, then turn it back on again. Sorry, PeteMac, that I left that mystery unsolved. But it happened to me again this evening and I had to go back to the original thread to discover the solution I had posted about. I suspect that Airport and Bluetooth have the potential to interfere with each other, but they can avoid that, if given a second chance.

The following from: http://forums.macosxhints.com/
Okay. I went back and found an old trick that never worked for me before but now it does. You need to edit the user/library/preferences/.globalpreferences.plist. This file is invisible. What I did was open it with SNAX (it can show invisible files) by dragging the pref file onto TextEdit's Dock icon. You could also use TinkerTool to make the file visible or perhaps do the whole thing in the Terminal.
Look for a couple lines that looks like this:
<key>com.apple.mouse.scaling</key>
<real>1.000000000000000e+00</real>
[the first digits might be "1.7" or something depending on how you've got your mouse speed set]
Change the last part to look like this:
<real>1.000000000000000e+05</real>
This should bring the acceleration tracking curve to "normal." You can try changing the first part to speed up the mouse like this:
<real>4.500000000000000e+05</real>
You need to log out for the changes to take effect. If you go to the mouse System Preference and change a thing it will overwrite your changes and you're back to square one. I'm not sure that I've had much success in changing the mouse speed but the more annoying thing, the weird acceleratin curve, is fixed.

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

Mighty Mouse track ball button

I have been using Snow Leopard for a while and one of the things that I like the most is that I can choose what I want to see in my screen when I move my cursor to the lower right or left corner.
I have it set up as to SHOW ALL WINDOWS if I move my cursor to the lower right corner, well after I moved to LION that is no loger an option, instead of showing all windows open all it shows are the open windows open of the same application only, How can I set it up the way it was before, is there like a script or something.
also can it be set up so when I click the tracking ball on my Might Mouse to show ALL windows and not just the program windows?

I've read all the posting about this..in recent months I've been cleaning the track ball 6,7,8,9....times every day. I had planned to buy a wireless Mighty Mouse but not now, it'd be cheaper to sit in front of my Mac bashing my testicles with a mallet for the same effect. Apple, this is an utter design disaster. Like Joachim says, why not a mouse we can open and clean easily, or a larger, more robust track ball mechanism? I'm off to but a mouse by anyone but Apple...

Mighty Mouse Track Ball

Does any one else have issues with the mighty mouse track ball?? My does not work half the time. When it is working it will only work in one direction half of that time.
Does anyone know of ways to clean it?? Or keep this from happening?
