Possibly prevent a 'Bluetooth unavailable' error Laptop Macs
If you encounter a "Bluetooth unavailable" error message once in a while on your portable Mac, try disconnecting your Bluetooth devices before you shut down / restart.

You can disconnect your Bluetooth devices by either switching them off, or by going to the Devices tab of the Bluetooth System Preferences panel, selecting the active device, and pressing Disconnect.

As long as I disconnect my devices first, I never see the error message.

[robg adds: I haven't seen any such issues on my MacBook Pro, but I figured this might be worth a shot for those who are experiencing the problem. If you have Bluetooth issues and try this hint, please post your experiences.]

I just had this happen to me on my MacBook Pro (the original Core Duo version.) I hadn't seen it before though I don't use Bluetooth much.

The fix for me was to simply kill the blued daemon using the Activity Monitor. The daemon comes right back automatically and it fixed the problem.

Another work around for bluetooth pairing problems that has worked for me in the past: pair the new device using an administrator account on the Mac. I have had problems with non-administrator accounts when trying to connect a new bluetooth device where something "locks up," throws an error, and then corrupts the entry for that device. Deleting the entry, and recreating it while logged in as an administrator, solves the problem. The device then works fine from the non-administrator account.

I'm getting error and app crashes from using a bluetooth device
i bought a bluetooth earpiece to use with skype
I got it working once and that ended very quickly
Skype crashed
I also tried a audio test thinking that maybe it was skype
tried playing an mp3 though itunes guess what .....
itunes crashed :[

I followed all the steps per Apple support for set-up
I can get the device to pair ( well so the bluetooth set-up says )
but all I get is white noise coming from the earpiece if I try running audio through it

i will try your suggestion above
thank you

I am having this problem with my Powerbook G4 17" 1.67GHz where my apple bluetooth keyboard suddenly stops responding. I look at the Bluetooth status in the menu bar and it says the device is not available. As if I suddenly don't have bluetooth builtin. It's very frustrating, it even cut out just as I was typing this reply. Eventually it comes back, but I don't have the foggiest idea what is wrong. Here is my console log pertaining to bluetooth, I can't make heads or tails of it, but maybe someone else can.
