Q: Poor Bluetooth reception and jerky mouse

Hi guys,

I had the same problem with my Mac Pro and a Magic Mouse so I got a DLink DBT-120 and plugged it into my Cinema Display. At first it worked fine... unfortunately after 3 or 4 reboots my Mac lost track of the DBT-120 and re-activated its own internal Bluetooth card instead. Then I had to reinstall everything all over again. This was getting really annoying so now here's what I did:

I unplugged the little cable from my internal Bluetooth Card. This is located directly behind the cpu/memory-tray and really easy to pull/reinstall if I want to. So now the Mac Pro sees the DBT-120 as the only Bluetooth device and it works as it should!

@castelletta :

No, that does not work for me. But I am happy using the Mac Pro's Power Button or my USB Apple Keyboard for this. Sorry :-/

Just wanted to say that this is an issue for me as well with a 2009 Mac Pro. I've tried all of the possible software fixes to no avail. I've also tried removing the lid at the bottom of my Magic Mouse and that doesn't help. Moving it closer to the machine does work but it's not an option and it's only six feet away at the moment (it works much better when just two feet closer).

Anyone have any updates on this issue? I haven't been able to find instructions for how to make necessary hardware adjustments for 2009 Mac Pros...

Hiya guys and girls! Forgive me my intrusion.
I'm using x86 pc, Windows7 + usb mini bluetooth adapter with Small wireless bluetooth keyboard and Magic mouse, ofcourse
I have installed extracted bootcamp driver to use my MM with Win7, it's not 100% functional, but... anyway

Anyway all this does change nothing, i think, becouse...
1) my mouse lags all the time with my desktop computer, just like yours (MM)
Checked with MouseRateChecker software. Normal rate 80-90hz, then lag occurs it's 0-10hz and 1000hz for a sec. after lag! Crazy?

2) experiment, using the same bluetooth dongle and MM with ANOTHER pc (laptop). Running Windows XP.
= NO LAGS at ALL, totally, really!
3) same adapter, same MM. Laptop under Windows Vista control.
= same shocking result - No LAGS!

All operating systems are x32 (x86).

So... the only thing i can be sure in right now is - my Magic mouse is alive, in normal condition and normally working without lags.
Just guessing - your MM should be working too! And no reason to change it in AplStore to another same MM again and again.

"Our" problem - sofware, driver. Corrupted. Unsupported. Conflicting. Not perfect for all hardware.

That's becouse it works with one computer and does not work normally with another.
Can't say that all MAC's are the same (different configs, different date of manufacture, even if same brand and tech specs) so... i may assume that my argument can be used even for MAC users.

+ different software and drivers installed on MacOS, that could affect and cause problems with MM too.

Apple, hello!!! That's not your style, to release for sale unfinished untested product... PLEASE FIX !!!

ps - sorry for my broken english, my Russian pet bear just prevents me from typing normally :\ eh vodka vodka...

Just kidding

ps - my Wireless keyboard works ok, no sticky keys or lags at all
pps - and i'm sure that reason in MM lag is not in interference with bluetooth signal from WiFi or home radio phone or anything else.
I even tested MM + laptop at 1cm distance from working microwave oven!!! Do you know that oven has same ~2.4hz frequency as WiFi, bluetooth, radio keyboards\mice and radio phones? Hehe.
Nothing could affect signal from adapted to MM.

Add me to the problem. I just bought a shiny new Mac Pro 8-core. I already had the Magic Mouse and it worked fine with my last computer - a G5 quad-core - which uses the same case. The mouse works fine with no tracking or stuttering issues, but only as a mouse. If I go to the Mouse control panel and choose to setup a bluetooth mouse, the computer never finds the it - even if I hold it directly in front of the computer. Having to buy an additional adapter is not what I had in mind when I dropped over three grand on this computer. Apple, any ideas?!

Hello dear all,

now 10.6.3 is released - so my question: is this issue solved? Does the Magic Mouse now works fine?

Thank you
& best regards

...I sold this mouse, but I would prefer to use this mouse

Just downloaded the updates. IT STILL DOES NOT WORK. SHIP.
The documenation does not mention any mouse or bluetooth fixes either.
I will be contacting Apple today.

It seems that I have just fixed my similar problem. Mine is one of many MacPro's shipped with the wrong wiring of bluetooth antenna. Followed the wiring suggestion on this URL:

MagicMouse seems to be working well with no jitters or delay. Let's see if it holds. Hope it works for many of you out there. Good luck.

Hi Castelletta, you meant rafnavri, not Mosaica. I do have, as you know the early 2009 Mac Pro with the New problem not the old bad wiring problem....

I have made contact with my Apple contact and will be back with some update info here soon.

I am experiencing the same problem with my 2 x 2.26 GHz Quad-Core.

Am interested in the antenna replacement solutions offered by GuyWittig and sixgunaz. Will see if I can find and order the correct antennas.

Perhaps the ideal solution would be to order an antenna of sufficient length that it can extend out the rear of my tower, around behind my monitor, and can be affixed by tape or glue to the front of my Magic Mouse--thereby eliminating any chance of signal-strength issues. This might give me the trouble-free wireless mouse experience I've been hoping for since purchasing the hardware.

Seriously though, I love Apple and would very much appreciate an acknowledgement of and solution to this problem.

So the 2009 Mac Pro Quad Xeon i bought yesterday is doing the same thing.. $5000 with the monitor and I have Jerky Magic Mouse from 3' away.. Mac Pro is right under the desk.. Unreal..

I pulled out the CPU tray and sure enough the Bluetooth Card is right there with the Antenna Connector.. The antenna runs up into the case somewhere where I cant see it ? Is there an easy way to remove the whole wire and pull it out ? If we ran the wire outside the case, I am 100% sure it would fix this problem..

If we can just find the antenna sold separately , we could just buy another antenna and connect it and run the wire out the back and I am so sure it would fix this..

This so much looks like an antenna issue.. I dont think for a second that its in the OS or can be fixed with the OS..

It seems like straight RF issues and an external antenna would fix this.

So now where can we buy the antenna to try it ?

If anyone knows how to get the antenna out of the 2009 Mac Pro easily please let me know

Thanks
