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,
- Doug

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 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

Wireless Keyboard and Magic Mouse (Bluetooth) Problems

Hi folks,
I recently got a new Mac Mini, wireless keyboard (Apple) and Magic Mouse. During high LAN activity, the keyboard and Magic Mouse will often lose connection and will have trouble re-connecting even when LAN activity goes back to basal levels. If they do not lose connection, the performance becomes terrible and both lag significantly during use.
This behavior does not happen on my MacBook Pro.

Other things to check-
Do you have anything on top of your mini, or is the top of the mini under a desk or other obstruction? The bluetooth antenna is (as you are looking from the top down at the mini) to the top right of the Apple logo on the plastic case top. Try clearing any clutter (if there is any), or establish a clear line of sight with your keyboard and mouse to the unexposed top of the mini and see if the dropouts occur.
Also, microwaves wreck havoc with bluetooth. Any machinery in the same room as your mini and keyboard/mouse?

Magic mouse click problem.

Hi all,
Couldnt find any solution yet for my problem.
It is always either not click or in click(can see the dragging box).
No problem with connecting & tracking.
I'm using iMac

Hi decavalera,
Welcome to the Apple Support Communities!
If you are having an issue with the clicking on your Magic Mouse, please follow the troubleshooting steps in the attached article.
Troubleshooting wireless mouse and keyboard issues
http://support.apple.com/kb/TS3048
Mouse buttons do not work as expected.
The Mouse preference pane allows users to customize the mouse features to meet their needs.
Choose System Preferences from the Apple () menu, then choose Mouse from the View menu. Set the Tracking slider to adjust how fast the pointer moves as you move the mouse.
Try using a different surface to see if the tracking improves.
Turn the mouse over and inspect the sensor window. Use compressed air to gently clean the sensor window if dust or debris is present.
If multiple Bluetooth wireless devices are in use nearby, try turning them off one at a time to see if the issue improves. Bandwidth intensive devices could affect tracking.
Have a great day,
Joe

Magic mouse bluetooth problem

I have a blutooth dongle on my mac. As batteries were getting low in my Magic Mouse I removed the old batteries and put in new charged ones, something I have done numerous times before without a problem. On this occasion I cannot get the mouse to pair with my computer for some reason. I have checked using Bluetooth Explorer and the dongle is shown as active. (The Blutooth provided in the Mac is useless hence the dongle) Any suggestions?

You can only pair it with one machine at a time. So you have to unpair it with one machine before yoou can pair it with the other.

Magic Mouse accessibility problem

Have discovered an accessibility problem with the Magic Mouse. My right hand middle (right click) finger is heavily bandaged at the moment. Mouse will not accept right clicks, even all the way on the edge. Interprets them as left/single button click. Went to Universal Access in System Preferences, and there is no solution. This seems like an obvious issue for people with prosthetics, so I don't understand why Apple designers missed this.

yerdle,
It's not the best of solutions but you can hold the Control key down while you click and it will perform a right click.

Magic Mouse Clicking Problems

Hello, I've just noticed that the far right side of my Magic Mouse stopped to trigger a proper click, thus I cant really make right clicks any more, only if I press it down quite strongly. My Magic Mouse is now a few months old and I've actually never experienced any problems before.
I could imagine that dust and dirt accumulated in this small slit that goes around the mouse prevents the click. Is there any way to open the Magic Mouse in order to clean it?

I got exactly the same problem, but the folded paper solution did not work.
¿Any suggestions?
Thanks for your time
Regards

Magic mouse switching problem

I have a magic mouse about twelve months old. It periodically switches off. Problem: when switched on the light comes on for about 3 secs then it starts 2 flashes every sec. Have tried new batts, shaking, clicking, tapping and all usual things but no go. It seems softwarde related but what. any suggestions please?

Hello:
If the mouse turns itself off it is probably faulty. If it is still inside the one year warranty, get in touch with Apple at once.

Magic mouse range problems

Hi all,
I am having difficulties with my new Mac mini in regards to my magic mouse.
The problem is it works fine right next to the machine but as soon as I move it onto my bedside table (barely more than 1.5meters away) it will stop working. Surely it is not out of range as apple website quotes '33 feet' as the range.
Is there a fix for this? There isn't anything interfering as far as I know. Batteries are fresh, perhaps the mouse itself is faulty?
Please help its driving me crazy!
Thanks,
CJ

Do you think I will have the same problems with a magic trackpad?
That's what I would expect, but maybe the trackpad has a better radio. The only way to find out would be to test. A better approach would be to try to eliminate or reduce the interference.

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.

Frerk,
Here's an apple article on possible causes of interference:

HT1365 Magic mouse connection problem

Hello, I have a problem with the magic mouse for my imac constantly connecting and loosing connection. Batteries are 100% and the keyboard stays connected no problem.
The computor is brand new. Any ideas people?

From scanning the forums, there seem to be two suggested approaches to fixing this.
Make sure your batteries fit tightly- the Apple rechargeables tend to fit OK, but some others can connect loosely. Try a folded piece of paper between the batteries and under the battery door to hold them snugly in place.
Remove any possible sources of interference in the 2.4Ghz band- Move your DECT phone further away. Switch to 5GHz wifi for the macbook and phones or ipad if you can. If needs be, turn off possible sources of interference in this frequency range in your location one by one until you can isolate the problem.
This has been a problem on and off for a year or so.
I've just tried the bit of paper, and it does seem to be helping so far- fingers crossed.
Good luck
Peter
