Hi Jon,
I'm not using Bluetooth on my Mac, but a quick Google search showed
that people are reporting issues with Bluetooth after the 10.6.5
update. This is ironic, since one of the features of the update was
supposed to be improved Bluetooth stability and connectivity for
Braille devices. You might want to check through the Apple Discussion
forums for solutions. I read one thread titled "Bluetooth disabling
after 10.6.5 upgrade" where a couple of users were finally able to get
things working after completely powering down their iMacs, unplugging
the power cords, pressing the on/off button (I assume this was to
discharge the capacitor), and leaving everything off for half an hour
before restarting. I'm not sure how those instructions would
translate for other Mac devices. They unsuccessfully first tried
repairing permissions, zapping the PRAM, re-downloading the combo
update, and booting up from the DVD, among other things. that did not
work for them. Although, the one time I had to apply a fix to a
relative's MacBook USB port problem by resetting the PRAM, the
AppleCare tech (on the phone), told me to unplug and turn everything
off, then remove the battery and hold down the on/off button for at
least 12 seconds before putting back the battery. In case this helps
you I'll paste in the details on resetting the PRAM:
1. Power down the computer and remove the battery from the MacBook.
(On my model you need to get a thick coin, like a U.S. nickel, to
insert in the slot of the lock for the battery, and give it a quarter
turn clockwise to rotate it into the unlock position so the side of
the battery near the lock will pop up, and so that the battery can be
removed.)
2. With the battery removed, hold down the power button for at least
12 seconds.
3. Replace the battery. (On my model, you insert the side near the
left edge of the laptop so that it engages, and then swing the other
end so that it slots into the lock position. Then you use the coin to
turn the slotted lock a quarter turn counter-clockwise to lock again.)
4. Hold down the Command, Option, P, and R keys while you power on
your laptop. I press down the Command, Option, and R keys with my
left hand (little finger on the Option key, ring finger on the Command
key, and either middle or index finger on the R key). I press the
thumb of my right hand on the P key and push down on the power button
with the middle finger of my right hand.
5. You need to keep the Command, Option, P, and R keys pressed for at
least 3 start-up chimes before releasing them in order to reset the
PRAM.
6. Log in as usual and check your USB port connections. (In your case,
try checking the Bluetooth performance.)
HTH. Try Googling about this and maybe you'll find more information
about a solution.
Cheers,
Esther

Hello,
In 10.6.4 I was using my Halo on occasion to work with VoiceOver,
and found that it worked better than in earlier versions. Last,
week, I upgraded to 10.6.5, and had the first need to work with
headphones this weekend. I had significant problems:
1. VoiceOver / Alex started stuttering, and turning on/off the
Bluetooth connection every phrase. Then when I shutdown the
bluetooth audio I discovered several functions of the keyboard had
stopped working. Is anybody using bluetooth regularly for their
audio output with 10.6.5? If so, did you need to adjust any non-
standard parameters to make it work?
I am planning on getting somebody with sight to look over the system
profiler while I try using the headset again, but before getting my
family grumpy at me,I wanted to illicit any ideas from this list.
Thanks,
JOn
