    To most who use Mac Pro 09/10 may find there is an issue working with Bluetooth devices as there is an design issue with the Bluetooth antenna which was hiding behind the aluminum and absorb the bluetooth signal.

    I've been searching around and finally decide to share the experience and mod which to solve by using an external antenna.:)

    Below are the parts for the mod and the final result was super no more jerky or mouse disconnect and smooth mouse experience.:D

    I got the U.FL to RP-SMA Female Pigtail from Ebay at a very nice deal USD3.99 for 2 pcs include of postage.

    The 2.4G antenna are from my faulty old Dlink wifi router and the back plate are from my old silverstone fan controller so its a very cheap mod with fantastic result. Time take is less than 10min to have everything done :D

    Tq :)
    yes that's the right cable and length. If need to route under the logic board u may get a longer cable but I think it's a bit hard to get above 25mm in length. :p

    Wouldn't the thread below have worked also or is it a completely different problem ?

    Yea to retain the wake from Bluetooth on the magic mouse and to save a USB port from Bluetooth donger this is the best solution. :)

    Great mod; I wish I had an available PCI-e slot to do this since my Magic Mouse, at times, can be just about unusable.

    Thanks for sharing. Personally, I disconnected the internal Bluetooth antenna to use a USB dongle (I plugged out the tiny cable that is visible on your photo) I wake from sleep by dis- and reconnecting the dongle. It takes a few seconds, but it works...

    Nice work... I like it.

    This is what I did some time ago...

    It's not nearly as clean as this solution. I may try to procure these parts and update my solution to match yours.

    It may be tough finding the external antenna, I'm guessing since I don't have a dead DLINK router to steal one from.

    Nice clean solution but it does of course tie up a slot. What did you use for that slot plate? It looks like it has pre-cut punch-out holes.

    FWIW, I also use a dongle. You don't need to disconnect the internal BT antenna to use it (on my late 2010 Mac Pro at least) since the dongle takes precedence. And all I do to wake my machine up is hit a key on my keyboard.

    While yours is not as "clean" as feins' I am wondering why you strung your antenna wire where you did as opposed to going out through one of the many holes in the "cheese grader"? That way the slot is available.

    Yes its from my Silverstone Fan controller back plate which was precut with 3 holes and its just nicely fit. If you dont have one of this you can just drill a hole on any backplate no worry still serve the purpose.

    Yes it will do even with a USB dongle but not all happen to be lucky as you as i encounter there are issue with some, after wakeup the Magic Mouse wont respond or you wont be able to wake ur Mac up with the bluetooth keyboard. So the safest mod is still using back its existing bluetooth module by replacing its original antenna which suck. Im not sure why apple still dont solve this issue with its Mac Pro 10 model if do i will just buy the Mac Pro 10 model antenna to replace mine to save a pci-e slot :rolleyes:

    Which exact dongle do you use?

    On my 2009 the dongle I use does not reliably work without disconnecting the internal antenna. I've been searching the web a while ago, and this appeared to be the general experience with various dongles, including the D-Link Apple sold in the Apple Store. Did Apple finally change something on the 2010 to prevent this?

    Well let me clearify my previous remarks a little. First I have a USB keyboard directly connected to my machine which is why I can wake the machine up by hitting a key. And also, maybe 15%-25% of the time it is indeed true that my MM won't respond after waking up either. In those cases I need to flip the switch on the MM (or press the button on the trackpad a few times) to "get the dongle's attention" (so to speak), or as I like to think of it as saying "over here stupid" :D

    I use a IOGear Bluetooth 2.1 USB Micro Adapter GBU421. I only got that particular one because they were on sale for $8 at Fry's last Christmas. I keep it plugged into the back of my ACD which means it's less than a foot or two from the mouse and trackpad.

    I knew when I decided to use a USB dongle that the any BT device like the mouse wasn't going to be able to wake up the machine since the power is off the dongle while the machine sleeps.

    Well I did qualify my remark by saying the dongle takes precedence on at least my late 2010 Mac Pro:) But are you 100% sure about having to disconnect the antenna on the earlier models? I originally discovered that the dongle was taking precedence while I was playing around with Bluetooth Explorer because I was initiialy concerned who was going to receive the BT signal -- dongle or built-in. I think it was the "HCI Controller Selector" which shows the "Host Controller Selector" window. No other choice is given except the dongle when the dongle is plugged in.

    Maybe on the earlier models there is a choice so perhaps you could select the dongle from there as an alternative to disconnecting the antenna (just thinking out loud here).

    Bluetooth problem

    Hello,

    Have a 2010 6-core Mac Pro.. Although I have not experienced any such problems mentioned in this thread, how do I know if I have this problem? My bluetooth connects flawlessly and with no problems.

    Then I guess you have no problems :D

    If you have such things like intermittent, jerky, or lagged mouse response (any of these in any combination) then you would probably have noticed some of these BT problems.

    This also applies to the trackpad too. I don't have a BT keyboard so can't comment on how it would behave (miss a keystroke here and there I assume).

    I have to also assume you have your BT stuff "close enough" to the back of your machine with little or no obstacles to interfere between there and your BT device(s).

    Neither end of the antenna would fit through the cheese grater holes. The only exit that worked, was through a slot. The slot is still usable though. At any rate, this is a far superior solution and I will be switching to this as I don't need all my slots anyway.

    EDIT: It appears the same EBAY seller of the pigtail cable, also sells a suitable 2.4GHz antenna

    Don't quite remember exactly, really. Will have a look into that again. So your dongle only took precedence after you took care of that with the Bluetooth explorer or using the bluetooth explorer you noticed it takes precedence by default?

    Here's a guide to the plug-out procedure that I had bookmarked:
