Dear friends,

 

A bluetooth problem is driving me crazy.

 

I have a mid 2010 15" macbook pro and there is a frustrating issue.

 

I kept using my apple bluetooth keyboard and magic mouse perfectly for a year or so in snow leopard. After Lion update they were so lagish and jittery that I couldn't control my mac. After researching and asking the apple discussions I found a solution which is deleting the apple.bluetooth.plist file from Macintosh HD/Library/Preferences folder and performing a PRAM and SMC reset. This solution, though, is not permanent.

 

Every time my computer goes to sleep or after a couple of days, the problem unveils again. Applying the same fix, both keyboard and mouse magically work again perfectly.

 

I seek for a permanent solution and maybe also an explanation ! It is quite irritating performing every other day a PRAM and SMC reset, not to mention that it doesn't feel quite normal doing those things so often...

 

I also tried doing a clean erase and installing snow leopard again, but the problem appeared again !

 

Thanks

    Note that if I turn bluetooth off and again back on, the problem dissappears for a very short period. Some times 10 minutes, some other times 30 seconds....

     

    It seems like nobody has a suggestion, though...

    Unbelievable,

     

    After weeks of frustration and search I solved the mystery...

     

    Wifi was interfering the signal ! I moved my desk and that's why the symptoms started....

    Incredible. Just replaced my aged Mac Pro 1,1 with a shiny new Mac Pro 5,1

     

    My brand spanking new $6,000 system had Bluetooth issues out of the box. Both wireless KB, Magic Mouse, and Wireless Pad had jittery responses, and often loses connectivity. I'm 1-foot away from the tower. New batteries. Come on Apple, what's up??

     

    I've reattached my old 1.1 wired keyboard and mouse. Pretty sad.

    Try turning off your wifi. If that solves the problem, create a 5GHz band wifi network, which will not interfere with bluetooth's band.

    Thank you for your response!

     

    I have read that, however, our home is WiFi only without a run of CAT-5/6. We use WPA-N, and it's 2 floors below me, so I'm as distant as possible. Turning off WiFi will disable connectivity to all computers, mobile devices, and streaming sourses to several rooms. Not a viable solution for us I'm afraid.

     

    I've read elsewhere that buying an external BT USB radio would be a viable work-around, giving stable connectivity and even increasing distances to 15-30 feet. I may try that, but good grief, why doesn't Apple make their products 'Just Work' without such work-arounds??

    Just try as a diagnostic test. Turn wifi off for a while and report back if that solved your problem.

    Thank you again for getting back to quickly.....

     

    As suggested, the WiFi was turned off, and the issues remain unfortunately. It doesn't appear to be a WiFi issue, at least for me.

     

    Troubleshooting Comments:

     

    I have noticed the erratic behavior of the BT devices become worse as I utilize my external storage devices.

     

    One utilizes eSata via a NewerTechnology toaster, and the second one uttilizes USB3.0 via another NewerTechnology toaster, both sourced via a CalDigit Fasta 6GU3 PCIe card.

     

    The erratic behavior was evident before adding the PCIe card, but does become worse as devices attached to this card are utilized. Unplugging the drives helps a little. Removing the card doesn't change the scope of the problems.

     

    Plugging in standard USB2.0 products for some reason stabilizes BT. For instance, if I plug-in my old Mac Pro wired keyboard and mouse, the wireless keyboard, mighty mouse and pad become more stable as well.

     

    System Information does not report any anomalies, and calls into CalDigit offer no suggestions. I have ensured all updates are current from CalDigit, after uninstalling and reinstalling their drivers as well.

     

    If I had to wager a guess, while USB and BT are two completely separate entities, they appear to share a common incompatibility.

     

    I must stress that this problem came out of the box, without initially adding any new applications or updates to the Mac Pro. Having exported and updated everything, the issue remains. A most peculiar problem.

     

    I believe I will try the USB BT dongle approach. I had read that Apple (Their claim) had recommended this device (D-Link DBT-120 USB BT Adapter). The URL for that string came from: http://nobblynoel.wordpress.com/2010/04/25/mac-pro-2009-bluetooth-fix/

     

    Thank you again!

    Found the issue, and it now works flawlessly.

     

    Completely different workaround that cost nothing, and took about 5 minutes to complete.

     

    All my devices such as the wireless keyboard, wireless trackpad and Mighty Mouse work together without any problems, and now have a working distance into the next room. No more jerking, loss of connectivity or other related issues. And this is with my 2.4g WiFi working at the same time.

     

    Apples response to being  a 2.4g WiFi issue is not entirely true. While it can conflict with Apple's internal BT module, it has no problem working with 3rd party BT devices using the same frequencies. Apple also said I could not use the Mighty Mouse and the wireless trackpad at the same time. Again, this is more than likely true with Apple's BT internal module, but not with 3rd party BT devices.

     

    Adding the 3rd party USB BT device WILL cause a conflict with Apple's internal BT device, and the Apple BT device must be deactivated entirely. This was my initial problem.

     

    While the work-around does not violate the warranty, I choose not to write about it here in case their damage control department chooses to use me as a scape goat. Paranoid?.... Ummm .... Yes.

     

    If you Google the search string, "Mac Pro Bluetooth issues solved", you will probably discover what I did. This requires no tools, nothing to buy, and about 5 minutes of your time.

    I tried two BT Adaptors but with the actual OS it does not help at all - waste of money!

    Nice try - but I think it is just a wishfull thinking approach..

  • 11. Re: Bluetooth keyboard and magic mouse issue

    Bill....

     

    I assume one of the adapters you tried was the D-Link DBT-120 as referenced above?

     

    I also assume you performed the internal hardware disconnect as referenced above?

     

    These two solutions applied together has been working flawlessly for me. Although, it took much testing to get there, as I also had used other 3rd party BT's first, and didn't perform the hardware fix until later. If you have done both, then I can only guess that it falls under Apples Law (Cousin to Murphy's Law). Sadly, Apple products don't "Just Work". I had been fighting this issue since 2006 until I tripped over this back door.

    I was using a iogear GB412 bluetooth adaptor with a Mac Pro because the Mac Pro bluetooth is useless.

    The Magic mouse would connect ok but then i had the same disconnecting problem, at random.

    Changing batteries and bits of cardboard diddn't help either.

    What i did find was that i was using a USB extension and had the adaptor on my desk, thinking that the closer it was to the mouse the better the reception would be.

     

    Then i moved the adaptor away from my desk to the other side of the room... again using a USB extension.

    Since i moved it away from the desk it has not disconnected once. I use 2 32 inch tv's as monitors and have a fair bit of recording equipment in the room.

     

    With moving the adaptor away from everything i guess that there must have been some sort of interference from maybe the monitors or other eqiupment.

     

    I know this is not much help for laptop users but could be of use to someone... it worked for me.

     

    I have my Mac Pro outside the room i work in with a usb extesion running through the wall and the adaptor plugged in to that, now it sits about 3 meters away from my desk and has no disconection problems.

    Works for my MacPro after endless exercises with all the other recommendations. Forget about anything else but use the link "Mac Pro Bluetooth issue solved"

    Thanks!
