I want to share my findings upon the poor reception of the internal Bluetooth module on my 2009 Mac Pro. The mouse in particular seems to suffer the most from the low BT signal.

It has to be said that if you succeed to place your Mac Pro in a particular position you can obtain optimal mouse reception. It seems that the field covered by BT signal is very irregular (due to the aluminum case?) and I think also altered by other metal objects that can exist on your desk (or inside/under you desk and his structure).

This can explain why some users tell of fantastic BT reception with their Mac Pro and others (majority) complain about awful Magic Mouse tracking.

In my situation I've been forced to plug-in a D-LINK DBT-120 dongle. It performs very well and maintain always connection with mouse and keyboard upon restart......unfortunately the same peripherals can't awake my Mac Pro during the sleep mode. A little uncomfortable (because you have to press the power button) and I thing very strange since this dongle is considered the only BT dongle fully supported from Apple.

I tried other dongles but all seem to lose connection. Some after restart, others after sleep mode.

For sure it's a shame that the most powerful and most expensive machine that Apple is selling right now is so badly performing in the BT compartment and it's more unforgivable since Apple seems to push very much their wireless peripherals.

Ok Apple, it's not easy to grant a powerful BT antenna in the metal case of the Mac Pro? Well please provide or support an external module that fully support all Mac OS functions (key selection on startup, wake on sleep ... etc) and consistently. I don't think it's a science fiction task.

I'm waiting your experimentation in placing your Mac Pro differently.

Please share your experiences....thank you

    This issue has been discussed many times. It's usually because the Mac Pro is wired wrong. Nobody seems to know why it was done like that or why Apple haven't changed it, but changing it yourself fixes bluetooth issues.

    Here's how to do it:

    Very simple, fixes everything, and means you don't need to use a dongle...

    Mine works fine if unplug my router. I was told by Apple that Bluetooth and the Wi-Fi share similar signals.

    Hello Castelletta, I would like to share my findings as well.
    I have a 2009 8 Core Mac Pro, brand new and less than 30 days old (bought from

    I have a bluetooth magic mouse and bluetooth mac keyboard that came shortly after my purchase of the mac pro.

    Both devices work great on my Macbook Pro and Dell Laptop, which both are on the same surface and same room as my Mac Pro.

    The Mac Pro is on top of my desk (within a foot range) and at no angle or distance does the magic mouse and keyboard work within a inch of pulling my hair out. Stuttering, connection lost, etc..

    I have tried turning off my Airport Extreme and Macbook Pro to see if there was interference with no noticeable results.

    Apple sent a tech to my house to replace the bluetooth module on the logic board and this did not fix the problem. It was also determined not to be software related, at least with my current firmware and OSX 10.6.2.

    I have seen where older models mislabeled the wire, this does not seem to be the case with the 2009 Mac Pro.

    It seems to me the reception is too weak and unreliable to use something that requires precise movements such as a mouse.

    I am currently waiting on a return label to receive a full refund, I feel exchanging for another Mac Pro will more than likely not fix the problem. Other than this, the Mac Pro is one awesome machine.

    I have exactly the same problem (2009 MacPro, Magic Mouse) -- also solved by using a D-Link DBT-120 dongle in one of the front USB ports.

    Interestingly, my old bluetooth Mighty Mouse did not have these reception problems. I also noticed, that Apple supplied an external BT-antenna plug on the former G5 top models that utilized an almost identical, all aluminum outer case design.

    Apple should supply an external BT-antenna that can be threaded through the holes in the case to the outside.

    When using the DBT-120 the "Allow Bluetooth devices to wake this computer" option is dimmed in my case.

    This DBT-120 solution does not seem to be very stable either -- my machine kernel-panicked already twice at startup (today and a couple of day ago)
