Q: Poor Bluetooth reception and jerky mouse

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

    D'OH!! I've got an external Firewire audio interface sitting on top of my Mac Pro. That's what's causing my problem. When I move the thing off my Mac, my Bluetooth problems clear up. I didn't even think of this until I started reading about the case being the problem, and I thought maybe this external rack-mount device of mine is causing some sort of interference by sitting on the aluminum case. Sure enough, it is.

    I've had the same lousy bluetooth reception on an august 09 mac pro. I took it to the shop and was told everything was perfect. I asked later at the Apple store about the new case but they don't seem to be aware of it. I just installed the external antenna fix suggested by nobblynoel and it works wonderfully. Whereas before everything was jerky at two feet, now it is smooth and quick at 25 feet. I used a 12 inch cable and it was plenty long enough. Thanks for the easy fix!

    if anything it's worse on the 2010 mp. i just bought 2 and the bt reception is terrible. the only solution is to use an iogear bt dongle connected to the rear usb port (you can't use a powered hub for this) via a usb extender cable up to your desktop.

    it's pretty embarrassing that a £4k mac won't work with it's own mighty mouse – especially when the mouse it only 6 feet away.

    best wishes

    Thank you Anonymoustache.

    I used your fix after posting up on this forum with a similar problem today. Your solution has worked a treat!

    I just followed the how to on my 2007 era Mac Pro 2,1 and fixed my bluetooth problems. I always just thought that BT mice sucked.. now they work!

    Thanks!

    this was a message by another user but i am facing the same problem and tried my level best to solve it. no success!

    "I was having issues with my Magic Mouse, to fix these issues I was advised to delete to files 'AppleBluetoothMultitouch.kext' and 'AppleMultitouchDriver.kext'. Well thankfully after doing this and rebooting my Mac my Magic Mouse was now working*.

    Unfortunately in the process it had also lost its Multitouch features, no scrolling, no zooming, nothing. Now i'm no expert but i'm guessing it's due to the lack of the two files I deleted?

    What I'm really asking is how would I go about getting these two files back? I understand it's probably against the rules to share with me with the exact files so is there a certain software update that will put these files back in their original places? I have tried updating the Magic Mouse software but it claims I already have it updated.

    Any help is greatly appreciated." by Pink

    please help! thanks!

    I have the newest mac pro, and I am having the same problems. The internals are sufficiently different from the prev models that I could not locate the antennae to switch or fiddle with them. Very frustrating, as my mouse is currently ~2 feet from my computer. It seemed to work better when I had the computer on the floor and directly under the mouse, unfortunately, it works out better (with my available space) to have it elevated about 2 feet and over 2 feet. This is very frustrating apple!! please fix.

    I'm having the same problem, brand new Mac Pro won't work properly with the supplied Magic Mouse unless it's 18" away from the internal aerial. At 2 feet, it stutters and has jerky scrolling (that's where I operate it). At 3 feet away, it's a joke, and at 4 feet, it stops working.
    I'm going down the path of extending the aerial outside of the cabinet, but instead of attaching the external aerial on the back, I'm going to fix it under the table (where it can't be seen), via it's magnetic base. Hope this clears up the stuttering.
    I must admit, I'm a bit peeved at spending £3.5k on a computer, only to find that the BT is cr4p! I never had any problems with any other computer or laptop, just the Pro.

    So, I've converted the BT aerial to external, and it's a revelation.
    Whereas before, I needed to operate the mouse within 18" of the left sidepanel, I can now scroll smoothly up to 25' (I can't get any further away just now because it's raining, and I'd need to go outside), and it works through 2 brick walls (but not 3).
    Very happy with it now. Big thanks to nobblynoel for his blog http://nobblynoel.wordpress.com

    Robert,
    Glad it worked for you.
    You have proved again that if you have a problem that my fix is sure the best fix.

    The nobblynoel stuff appears to be for a 2009 mac pro. But your sig says you have a 2010 mac pro. I thought the BT stuff was supposed to be harder to reach on the 2010's. Or is it? Do those 2009 instructions apply equally to the 2010's?

    FWIW I gave up on the internal BT for my mouse (and trackpad) and just us a dongle plugged into the back of my monitor.
