Magic mouse lagging constantly

My mouse pointer's lagging all the time. I'm using osx10.6 and I have a new magioc mouse and a macbook pro 3.1. I had the same problem with my mighty mouse and osx10.5. The problem seems to go away when I disable airport which is not a solution as i am connected to a wireless router. the lagging also stops for about ten minutes if i remove the batteries in the magic mouse for about 5 seconds. can anyone help me with this one? this is unacceptable! 1799 euros for a macbook pro and 69 euros for a f** mouse, both of which are from apple which supposed to JUST WORK. well it's clearly not working at all!

I'm having the same issue here and I think it's related to my wireless network. The lagging occurs only when the following are in place:
A- Using the Airport Express in the Kitchen
B- Using the Apple TV 2 in the living room (previously, on my 1st apple TV, synching was doing the same thing)
C- Doing a back-up on my Time capsule
D- Anything related to home sharing makes the MM lag
One weird thing is that I'm also having the magic track pad and it's not as nearly as bad and it makes me wonder if the issue is the mouse bluetooth connection.
One thing I've heard that may actually change that is to switch your network to 5Ghz band. My problem is that my wife use and old Macbook and my old iPhone 3 which doesn't work on a 5Ghz band.
Someone else suggested the following but it didn't worked for me:
1- hold down Shift-Control-Option, and press the power button ONCE. (don't start the computer, just quick press the power button).
2- let go of keypresses and start computer again.
if anyone has a solution to make my MM stop lagging, I would appreciate

Magic mouse lags bluetooth audio

Magic mouse lags bluetooth audio with cracking and pitch shift.
After Magic mouse disconnected, then bluetooth speakers sounds perfect.
Please help!!!

I have this same issue, but opposite. My audio in my bluetooth headphones sounds great, but when they are connected my bluetooth mouse (microsoft 5000) is all over the place.
What's the deal. I didn't know my $2000 mac would be so inferior to my $800 pc in this regards (otherwise very happy with switch to mac)

Magic Mouse lag issue.. new insight

Hey guys, as many of you i've purchased new magic mouse and been having problems with lag, and unresponsiveness.. I own a 24' imac which i bought a month before the latest update.. This whole situation is so bad for me that it really renders the mouse useless. However, i did find out few interesting things.. First off it only happens during the time HD is working overtime... For example if i am using apps that load up the cpu after a while it will start to lag. As soon as i turn them off, it all back to normal.. Games as well.. I recently tried to play world of warcraft with the mouse and it worked fine until the game made the imac go into overdrive and fans began spinning fast. The mouse started acting up again.. And most recently I realized it lags like **** when my time capsule is doing a back up.. As soon as time machine finishing working its all back to normal.. Very strange.. still no fix but that's what i could figure out so far.. Try it and see if you have those same symptoms.

A quick update to the jumpy mouse saga:
After a year of problems with a jumpy mouse (see videos below) *I purchased a Magic Mouse to see if the Magic Mouse would solve the jumpiness issue. It did but the tracking speed was very slow. Therefore, I installed MouseZoom to increase the tracking speed. After installing MouseZoom I started noticing the jumpy mouse problems again.*
_*This finding is very interesting!*_
_*It implies that the faster the mouse movement the more likely one is to see an erratic mouse with the pointer making unrequested jumps around the screen.*_
My hypothesis is that the operating system or processor is not allocating enough resources to the mouse if the tracking speed is set to a high level.
_*The "jumpy mouse" problem seems to be far worse when the hard disk is running - either copying or downloading a large file*_. Some users are reporting that watching a high resolution flash video will also cause the mouse to skip and jump.
I have tried three routers (two linksys, one Airport Extreme, three bluetooth mice, unplugging all peripherals still the same result.
I am certain the problem is software related because the same exact mice work perfectly in Bootcamp 2.1 and Bootcamp 3.0 in Windows XP SP3.
_*Youtube now has two videos showing the problem*._ You can view the videos here:
http://www.youtube.com/watch?v=NxLY3-pH-rs
http://www.youtube.com/watch?v=OBzisliiVpg
If you are suffering from similar problems may I suggest three actions:
* Use the Quicktime X screen recording function to record a video of the problem.
* Post the video to YouTube.
* Contact Apple Care and share your video problem description with them.
* Send a note referencing the video and description to www.apple.com/feedback
Category: Mac OSX Feedback
Feedback Type: Bug Report
Feedback Area: Peripheral/Device Support
I will update this video to let you know if the problem has been solved. I am hopeful that Apple will be able to find the source of the problem and solve it quickly. I really like my Mac and I can hardly wait for the problem to be resolved.
Here is hoping that 10.63 will resolve this issue once and for all!

Magic mouse lag on brand new MBP

Hello,
I received my MBP 15" (Mid 2012) several days ago. But my Magic Mouse doesn't work very well with it. The cursor lags every several minutes to one hour or two, and lasts for several seconds to several minutes every time. I don't mean that the movement is slow - when it happens, the cursor doesn't follow the movement of the mouse very well, it seems 'jittery'. The cursor may "jump" to the destination 0.3~1 second after I moving the mouse. I tried everything I can do but the problem is still not solved. Here are what I've tried:
* Setting my router to 5ghz band
* Turn the mouse off and on.
* Turn the mouse off, replace the batteries to new ones, and turn on.
* Restart the computer.
* Remove the mouse from the list of Bluetooth devices, and pair again.
* Reset PRAM and SMC.
* Disable WIFI.
* Unplug everything in my room that has a wireless receiver, including Xbox, Apple TV, etc, and remove the batteries of their controllers.
None of the above works! However, I also have a Magic Trackpad which also uses Bluetooth but it works fine. I tested the Magic Mouse on my old MacBook Pro and it works without any problem. The distance between the mouse and the laptop is less than 2ft.
Mouse still works fine on my old 2010 MBP.
Brand new MBP 15", 256GB SSD, 8GB RAM.

I had the same problem with my new Retina Macbook Pro and my Magic Mouse that worked fine on my previous 2010 Macbook Pro. At work I don't have a wifi network so I share my ethernet connection via wifi so I can get internet on my iPhone and iPad during the day. After reading this thread I tried turning off the internet sharing and it has cleared up all lag issues with the mouse.
Just thought I'd share my fix. Hopefully Apple can clear up whatever issues are causing this so I can get wifi back to my devices at work.

Magic mouse lagging on 40 inch screen

I have a 2.26GHZ Core 2 duo late 2009 Mac mini hooked up to a samsung led 40 inch disply with this cord.
http://www.monoprice.com/products/product.asp?c_id=102&cp_id=11215&cs_id=1024603 &p_id=9475&seq=1&format=2
The resolution is suprisingly good, the only problem i am having is that my magic mouse is lagging to the point where it is more than slightly annoying. I have the sensitivity set to just about the most sensitive setting but it doesnt seem to really make a difference. Should i replace the graphics card? if so how would i go about doing that?

The problem with the Mac Pro and the Magic Mouse is infamous. The accepted, actual problem is that the bluetooth antenna, labeled "BT" on the bluetooth card is NOT an antenna, is mislabeled, and was installed by people who do NOT speak English, thus the label could be "Fire Hazard" and it would be placed anyway.
I have gone many rounds with this problem. If you have an airport card in your Mac Pro next to the Bluetooth Card, then, there is a fix by swapping wires which can be found all over the Internet.
You can also add a WiFi antenna to the Mac and wire it to the Bluetooth card. There are instructions for THIS also on the Internet.
Second, you can get an external Bluetooth USB dongle, and use that. Unfortunately, on all Mac OSX versions prior to 10.6, the dongle will compete with the internal Bluetooth, generally canceling bluetooth function altogether.
On my Mac Pro, under 10.5.8, with no airport card, there is no easy access to the spare WiFi antenna, and so, my fix was to simply, and carefully, unplug the bluetooth antenna from the bluetooth card, unscrew the two screws HOLDING the bluetooth card, and, again, gently unplugging the bluetooth card from its motherboard socket. It now resides in a drawer.
Initially, my external bluetooth dongle (Zoom 4314), while supplying Bluetooth, could NOT connect to my MagicMouse with hours of trying EVERYTHING. Oddly, it took the system, which is NEVER turned off (much easier on the internal RAID), an overnight "pondering" to allow my dongle to supply functional bluetooth. In other words, after a night of massive frustration, all is well in the morning and the MagicMouse is not the best thing since sliced bread. It's BETTER than sliced bread.
All that said... apparently, MacOS 10.6 actually disables the internal bluetooth card when an external Bluetooth dongle is attached. Bravo.

Magic Mouse lags

Dear community,
my Magic Mouse often starts to lag when transmitting the signal to my Mac. This results in a sluggish and unresponsive cursor. How can I fix it? I am using the mouse on a normal desk, no transparent or otherwise ineffective surface.
Thank you.

Magic mouse lagging or unresponsive when using bootcamp windows 7 on Mac Mini but works fine in Mac OSX 10.8.4

I updated the Apple Broadcam built-in bluetooth radio software through Windows and it found an update. Updated Boot Camp software/drivers to version 5.0.33, the latest which includes a wireless mouse piece. Replaced the batteries again and turn it off/on several times. In the Bluetooth menu, this mouse usually does not show up in connected devices or will not show up as a device that can be added. Once it did show up right after turning it off/on but took forever to connect then lost its connection right away and couldn't be discovered again.
I don't think drivers are the issue, seems to be some kind of conflict with wireless adapter & bluetooth maybe.
I found this which looked promising but no luck: http://kemal.co/index.php/2012/09/laggy-magic-mouse-boot-camp-windows/
Any ideas?

Here's some trouble shooting tips for the built in iSight: http://docs.info.apple.com/article.html?artnum=93240

Why does Magic Mouse lag with new Mac Pro?

My magic mouse worked great on the old G5. Works fine an mini mac. Unusable on the brand new mac pro.
I have a $10 laptop mouse from an old pc that is wireless through a tiny usb connector that works 1000 times better.
Why?
<Re-Titled By Host>

I have three MM. One just does not work well. The other two are fine with the 2013 Mac Pro. Sometimes you have to clean the optical lens and sometimes they just don't work on any machine.

Magic Mouse Sticks Constantly

This problem is widespread and Apple is not addressing the issue anywhere I can see. I paid a lot of money to buy four Magic Mice in recent times and every single one of these displays this same issue; while they have always had “sticking” issues, a new wrinkle has been introduced, seemingly with the recent 10.8.4 updates to Mountain Lion, or perhaps with some other recent system update: The mouse cursor sticks in one spot and refuses to budge, it will only click and right-click in one place. It will randomly stop/start working constantly. I don’t know if it’s a Bluetooth connectivity option or something else.
Can someone please explain? I’ve deleted mouse preferences, Bluetooth preferences, reset the PRAM, tried another boot disk (with a slightly older operating system). The only solution that consistently works is using another mouse (non-Bluetooth) entirely.
Help! I truly use the advanced gestures in my daily life and it is a serious productivity issue to not have these features that I paid for!

Magic Mouse Lagging Problem

It's been three weeks since I purchased the MM and from the very start I noticed that after a little while when the mouse is idle, the scrolling does not respond for few seconds as if the mouse takes time to reconnect(pairing). Is this normal? Is this a bluetooth issue. Are other users experiencing the same behaviour? Please comment.

I had this same problem, for me it turned out that under Windows 7 the power management setting for the device "Apple Built-in Bluetooth" was set to allow Windows to turn off the device to save power. Try doing the following:
1) Bring up device manager and expand the "Bluetooth Radios" entry
2) Right click on "Apple Built-in Bluetooth" and select "Properties"
3) Click on the "Power Management" tab
4) Uncheck the "Allow the computer to turn off this device to save power" option
5) Click "OK" to save the change
Hope this helps,

Lost connection between Magic Mouse and iMac

My Magic Mouse is constantly losing the bloototh link with the iMac. I read in some forums that this bug is frequent with Mac OS X 10.6.8 but I haven't found any answers. BTW, batteries are not the problem since I have already tried it with several new batteries.
Could anyone please give me a solution to it?
Thanks!

Paul,
I don't think you did anything wrong. I think it was just "one of those things". Things should be OK now.
Give a shout if they aren't.

Magic mouse constantly disconnects and can't get it to connect without rebooting the computer. Anyone else have this issue

How do you solve the problem of the magic mouse constantly disconnecting? I have changed the batteries and turn it on and off, but the only way to get it to reconnect seems to be re-starting the computer. Any thoughts? Thank you.

Greetings Beth,
Wireless devices are susceptible to interference. Review this article for common sources: http://support.apple.com/kb/TS3048#5
They are also very sensitive to low power. Make sure you are using VERY fresh batteries. If they have been sitting on a shelf for months they don't count as fresh IMO.
Troubleshooting steps to try after you read that article at the top:
Remove the following to the trash: Macintosh HD > Library > Preferences > com.apple.Bluetooth.plist
Restart the computer and re-pair the mouse and keyboard
If issue persists reset the SMC:http://support.apple.com/kb/HT3964
If the issue persists reset the PRAM:http://support.apple.com/kb/HT1379
Hope that helps!

Why does magic mouse quits working constantly?

I have two Magic Mouse(s) and both worked fine from day one - early last year, and both now act up constantly with the same symptoms. I am among those who believe it has something to do with Lion. When I boot up, they don't get recognized and when I go to Mouse and search for bluetooth devices - sometimes they are found and most of the time they are not. I can reboot and sometimes get the mouse but often do not.
I know about adding the paper to help cushion the batteries, hasn't helped. I have the Advanced setting to wake computer with mouse - doesn't help. I saw some reference to booting with a control option and deleting some setting but can't find out exactly what that is all about. Love using this mouse, especially swiping, and want to make it work.
Right now I have one of those huge "ergonomic" bricks in my palm and can't stand it! Please let there be an answer.
Thanks

I think I have solved my own problem. My wife's Mac is just on the other side of the wall in the adjacent room. She came in to my room to tell me her cursor was moving all over the screen without her control. Guess what? My mouse was paired to her computer and while I was moving mine around to see if it would work, it was moving around on her screen! Not sure exactly how that happened but I went in and removed the mouse from her's and now my computer pairs with it as it is supposed to. Case closed for now.

Magic mouse is lag on Yosemite

My magic mouse is lag when macbook air mid 2013 was upgrade to Yosemite.
The mouse scrolling is sometimes slow but sometimes too fast on the safari page.
How to solve this is problem?

I'm on a Mac mini (Late 2012) running Yosemite (10.10.1) and had a lot of lag with my Magic Mouse. The mouse cursor would work smoothly for about 15 seconds then lag for about the next 15 seconds and continue the process all day every day since upgrading to Yosemite. I did the PRAM reset twice but it did not help.
Fixed for me:
Disable Internet Sharing
I came across this by accident when I noticed that my mouse was working fine all of a sudden and I went to reenable my internet sharing then the mouse started lagging again. Disabled internet sharing and mouse lag issues stopped. I'm also running Little Snitch 3.5 and I'm not sure if its a factor in the issue but it's currently active and mouse is running great. Will leave my internet sharing setting off.
Hope this fix works for someone else. Good Luck!

Magic mouse jumpy/lag/stutter/glitchy (macbook pro)

I just recently brought a Magic Mouse from the mac store, and I'm about to take it back. I've seen lots written about similar problems, jumpy/lag/stutter/glitchy mouse, but none recently that I could find. And none that have fixed my mouse.
The Problem:
My mouse is often jumpy, unresponsive and unusable. It jumps across the screen, either laggy or in a stuttering motion. I will then use the trackpad since I cant use the mouse and the trackpad works perfectly. So i know it's not a process running, or the laptop running slow.
It will sometimes work if it's just been sitting there a long time, like if I come back in the mornings it may work well for about 10-15 minutes, but then stop.
What I've tried: (With no luck)
- Multiple services, the desk, books, mouse pad etc.
- Changing batteries
- I even tried a trick of putting paper between the batteries because apparently the connections are bad and can cause the mouse to disconnect.
- I upgraded to the mac beta testing OSX, someone had tried that and it worked for them, it did not for me.
- One guy slams the mouse on the table and it fixes it... I didn't want to try that.
- I have compressed air, cleaning out the sensor etc.
- Having the bluetooth forget the device then reconnecting it
- I've also connected other bluetooth devices and had no issues in the past
- Resetting the pram and smc
- Prayed to Lord Jobs offering a sacrifice
My Macbook Pro:
Yosemite 10.10.3
MacBook Pro (15-inch, Early 2011)
2.2 GHz Intel Core i7
16 GB 1333 MHz DDR3
AMD Radeon HD 6750M 1024 MB
I like the look and feel of the mouse, and when it works it's great, so I hope i'm not forced to get some ugly logitec mouse or something...

Well, they have to, really. How else would they justify the cost of the 'free' replacement. Thing is, if you live near an Apple store you really must use their facilities. That is why you pay their prices for a quality item.
Don't think of yourself as being a nuisance, there is a certain entitlement in buying Apple ... and you are entitled.
