Dec 2, 2009 3:58 AMby castelletta,Do not forget:
a Bluetooth mouse like the Magic Mouse can track perfectly, without lags, without interruption, perfectly fluid as a wired mouse. With my external dongle the tracking is simply perfect as opposed to the sluggish tracking using MacPro internal Bluetooth module.
So if you experience some lags and/or disconnections take in account that this it's absolutely NOT a normal and unavoidable condition and that your mouse can work at best if Bluetooth signal is strong and constant.
Still I remember to all that although my external dongle solution (D-LINK DBT 120) is optimal for mouse tracking it's not exhaustive at all because during sleep mode mouse and keyboard can't wake the Mac Pro in any way. -
Dec 3, 2009 1:35 AMby castelletta,To me it doesn't seem a solution to turn off a router. It would be better to use a wired mouse instead
Remember also that the wireless router it's not the cause. I have wifi routers, AirPort around me and with my external Bluetooth dongle the tracking remains perfect all the time.
There is something wrong with the MacPro internal Bluetooth module. THIS is the problem. -

I have experimented by reverting to Leopard and find that the mouse is no longer jerky until the magic wireless mouse driver is installed. (Obviously without the driver the finger scrolling feature does not work). However I have no problem when using a Logitech mouse with wheel scrolling.
When the jerky mouse cursor is observed it will seem to have a 'vertical limit' it will move the cursor down but not up. It does not seem to be related to my router despite the Apple suggestion that interference with the 2.4 frequency may be responsible. I believe the driver is losing its pixel reference on the display and is the magic mouse driver update maybe the problem. The finger scrolling works fine even when the cursor is jerky. -
Dec 3, 2009 12:42 PMby castelletta,You are talking about a MacBook and similarities with Mac Pro are very few I think.
Apart from this I can confirm that my Mighty Mouse Wireless was jerky with Mac Pro 2009 well before the advent of the Magic Mouse driver update. And the same mouse now works very well with the external dongle and the driver update applied.
So to me it doesn't seems related. -
Dec 3, 2009 9:36 PMby Tom Alperin,I'm still not totally convinced that it is absolutely a problem with signal, however I have some ideas to try assuming that I might be wrong about this. The antenna is apparently on the bottom surface and relies on the signal being bounced off the surface the computer is sitting on. Wonder what material would be best to place under it as a reflector. I may just buy another USB dongle as I have a wired keyboard and wake from sleep not working on the mouse wouldn't be so bad as long as the keyboard worked. -
Dec 3, 2009 10:06 PMby Luba Cox,Well, I am giving up and getting a wireless mouse with a tiny receiver. I read it works on 2.4 Ghz which is quite crowded so hopefully no problems. The Magic Mouse looks great and if it worked I would have kept it, but surfing around there are better mice out there. Perhaps the Razer Mamba mouse?? -
Dec 4, 2009 1:49 AMby castelletta,Tom, do you think that Apple has to write this outside the Mac Pro package?
CAUTION:
use it only on a wooden surface, ideally far from anything electric or metallic
orientate it with the terrestrial magnetism
carefully place you at the right side of this machine if you really want to make use of a bluetooth mouse
never move your mouse too fast using this machine, it can be jerky
if possible, stick with a wired mouse and keyboard -
Dec 4, 2009 1:57 AMby castelletta,Luba, if you if you can live with an external receiver you can stick with your Magic Mouse and buy an external dongle.
Magic Mouse is really a pleasure for me. It's light and beautiful. The batteries last long and after installing BetterTouchTool it can do everything I wanted and more.
I'm really happy with it! -
Dec 4, 2009 3:52 AMby DaveClanMan,While I agree the hardware differs the OS software and magic mouse firmware are the same so some of the problems maybe related.
I believe there exists several BT mouse related problems.
1. RFI (as admitted to possibility of by apple)
2. Poor BT implementation on certain Apple products (fixed with external dongle).
3. Firmware driver related problem in OS X 10.6.2 possibly due to introduction of Magic Mouse finger scrolling.
The earlier BT mouse problem appear to be hardware related in your case.
Regarding my Magic Mouse problem I find that my pointer / cursor sticking problem appears to be 'Mouse Mat" related. I have reverted to a solid white surface for my mouse mat surface and the MM appears to work as expected. So maybe the pattern on the original mat was throwing the mouse ?.
The fact that in my previous experiment of reverting to Leopard to without the MM updates when the cursor/pointer worked without hanging or stuttering although without the gestures (as an old two button mouse) seems to indicate that the latest driver has very sensitive optical surface recognition.
So tip for Magic Mouse users 'try a plain mat surface' HTH -
Dec 4, 2009 7:07 AMby castelletta,I'm very skeptical about your theory mainly for a reason:
The Magic Mouse share a common element with internal Broadcom BT module and external DLINK dongle and this element is the Magic Mouse software driver.
In addition I can confirm you that my Magic Mouse linked to the internal bluetooth module works bad on ANY surface and linked to the external dongle works beautifully on ANY surface.
I experimented also without the Magic Mouse drivers weeks ago, as you suggested, and found identical problems. And my old Mighty Mouse Wireless exhibit the same exact behavior; and now it functions beautifully with a Mac Mini with the same bluetooth drivers.
