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.

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 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 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:

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 jumps all over the screen

*Magic Mouse is on Drugs*
OK so first, let me say that generally speaking i love my mac. There was a time in the 90's when i was a big Apple fan, but after a few dumb@ss business decisions by Apple, i decided to convert to Windoze (and my entire company at that) So here we are a decade later; and I'm back on a mac again.
Recently my MagicMouse started spazzing out. Randomly jumping to new points on the screen. At first it was mildly annoying. Now it's infuriating. I used Camtasia to record this behavior:
http://www.youtube.com/watch?v=fX8ApUH6QOw
I called Apple to discuss this. First, they said "they weren't aware of any issues" A quick google of "MagicMouse Jumps" returned hundreds upon hundreds of links (including this forum) describing the issue.
Second, after assuring Apple this really was a problem, i got the ultimate insult. "If you would like to lodge a technical support ticket, we will need your credit card. This call will cost you $150.00."
You see, I bought this thing four months ago. Apparently you only get a 90 day free call period. After that you're warranty is actually a cost per call scenario.....
So -- While i love my mac, i'm of the distinct impression i've made the wrong choice. The only good news is I've now decided not to convert the rest of our 20 workstations in my business back to Mac....
Apart from my b*tching, has anyone actually solved this problem that according Apple, doesn't exist?
Oh by the way --- plugged in a USB laser mouse, problem does not occur with that device -- tried on all sorts of surfaces; mouse pads, no mouse pads, black paper, white paper, patterned, non patterned, special optical mouse pad for laser mice.... SAME results no matter what the surface is, and YES, i've also cleaned the optics with a lens cloth..... (And the battery is currently at 88%)

Hello g:
Welcome to Apple discussions.
I suspect a faulty mouse. However, try two things first. Trash a preference file (com.apple.bluetooth.plist) and restart. Reset the PRAM:

There is no Apple charge for a warranty issue and the mouse has a one year warranty. Call Applecare back (or take it to a store if they have one close to you). Unless I am badly mistaken, Apple will replace the mouse and pay for shipping both ways (I had one fail a couple of years ago myself). Do identify the call as a warranty issue.

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.

Finger on magic mouse moving up causes the screen to move down on lion, was okay before on snow leopard

magic mouse commands changed from S Leopard to Lion, why?, and how can I fix. Ex. finger movement is now opposite the command on screen

Barry gave you the solution.
There is also a little tool called Scroll Reverser (now V1.4.2) that you can use (it gives a bit more control on scrolling left-right etc also):

Can I use my wireless keyboard and Magic Mouse with my 15 inch MacBook Pro retina display

Can I use my Magic Mouse and wireless keyboard with my MacBook Pro retina display

It has bluetooth. Why not? Please do so. (assuming both are functional)
Ciao.

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,

Magic Mouse Jumps After Update to 10.6.8 - Help!

Ok so I have updated my 2010 iMac to v10.6.8 and now my Magic Mouse randomly spazzes across the screen or is very slow to move. I have installed the supplemental update in the hopes of fixing the problem, also reset the PRAM and SMC, all to no avail. I've seen quite a few threads about this issue for Lion users, but have yet to come across one specifically for Snow Leopard users.
If there is one and I'm just being blind, please feel free to point me in the right direction.
If there isn't and there's something else someone with better knowledge of this kind of thing than I have can suggest, by all means let me know.
Thanks in advance.

Here comes the/my solution:
Remove Sophos Antivirus
Thanks to boojum's remarks in https://discussions.apple.com/message/15480849#15480849 !
Don't forget to use Sophos' deinstall package: /Macintosh HD/Library/Sophos Anti-Virus/Remove Sophos Anti-Virus.pkg
Nevertheless, some settings have been re-initialized (no complete list!):
- Dock
- Language has been reset to English only
- Expose & Spaces
(- probably all personal settings?)

Magic mouse does not swipe correctly

Upgraded to Mavericks. Magic Mouse only swipes between open screens instead of within pages in a document, returning to previous page on web site, etc.

Disregard. I looked a some other forums and checked my system settings. One finger swiping had been disabled. All is well.
For now.

Magic mouse right click not working

am i the only one? after downloading the latest os x updates, i'm unable to do any secondary click (right / left) with the magic mouse...tried everything via internet trouble shooting & even spoke with apple support...i have an appointment with their genius bar but there must be a way??? any advice apple fam? thanks.

No, you are not alone. I had exactly that situation with my magic mouse on my 27 inch iMac after the recent update of Yosemite.
I assumed it must be the mouse - just over a year old, so surprising.
But searching this forum I found the helpful posts suggesting deleting the com.apple.Bluetooth.plist file from Preferences. (Use Finder to go to your hard drive, open Library/Preferences and look down the long list of files to find com.apple.Bluetooth.plist. Drag a copy to your desktop, just to be safe. Then delete it from the Preferences. Restart your Mac and the file will be recreated.)
It's surprising that Apple staff aren't aware of this.
