Snow Leopard and Bluetooth problem

Hello every body..
Sorry for my english i am french
I have the same probleme :
OS 10.6.2 all update is OK but bluetooth is not available

i try to explain what i do for "retore" my bluetooth

i go to Macintosh HD/Librairy/Preferences/
i copy on my desktop com.apple.bluetooth.plist
i open it with properlist editor
*i delete :*
all DeviceCache
all PairedDevices
all PANServices
all PersistentPorts
i close it with save and replace the original by mine with authentication

And i shutdown my computer
unplug all cable
I wait 15 minutes
i restart it with only screen (without usb) keyboard and mouse
my wireless mouse and keyboard are off
and my bluetooth will be back
i plug my all devices and everything is OK
Try it
it's works for me ....

I'd try this but I don't have a com.apple.bluetooth.plist. I've downloaded PlistEdit Pro but don't want to screw my rig up by messing around creating plists with something that's over my head. Suggestions?

hello
did you have activate root user
If yes when you login with it
is the bluetooth is available ?
i can send you mine com.apple.bluetooth.com but you must change
DaemonControllersConfigurationKey by your bluetooth mac address

thanks sdaudet, had no bluetooth all of a sudden, tryed your solution: it worked aut great! used PlistEdit Pro

I did indeed login as root but the only BT pref I could find was in the Preferences subfolder By Host. And it wasn't com.apple.Bluetooth.plist it was com.apple.Bluetooth with a long string of numbers after it instead of just .plist

It sounds like you're onto something though and I'll gladly take you up on your offer to 'borrow' a copy of your modified Bluetooth.plist file. I'll contact you directly and give you my iDisk Public Folder info if you'd be so kind as to slip it in there.

Cheers mate.

EDIT: Maybe you could just email it to me as an attachment. I'm at longcat(at)mac.com

I send you a mail with plist file...

And...received.

You, sir, are a legend.

Will report back after I get home from work.

I installed Magic Mouse and all good until I went to the dark side (Windows XP Pro) and tried to install it there. No go - ok so went back to the good side and Bluetooth now not available and is not showing in preferences - re-installed applications = no change.

Back in Windows side device manager - bluetooth showing ok but has ! over Apple bluetooth icon.Tried repair and got the message error 43 and message that windows had shut it down due conflicts......

Would appreciate any help.
Thanks, B727.

Hello
It is the similarly problem
Try what i wrote before...

No luck yet so I'm thinking the gal who put this rig together for me (a developer friend from Apple) may have dislodged the Bluetooth antenna; this seems a fairly common problem with people who have installed extra memory etc. Just to be sure:

*I'm supposed to be doing all his logged in as root yeah? And the modified .plist goes in ~Library/Preferences as opposed to Users/Longcat/Library/Preferences yeah?*

II'm going to give it another shot or two resetting power management etc. I may even try and return to 10.6.0 and try it.

10.6.2 is making all sorts of trouble with everything from USB connected cameras and external drives to resetting default system prefs to something other than the factory settings (a thumb drive is my default device for sound?..really?!!!...</sarcasm>.

I've been using Macs since my first compy (a '94 Powerbook 500c that still works!) and I've never had so many problems with an upgrade. I went directly from Tiger to Snow Leopard so I don't know how 'bad' Leopard was. I told my pal at Apple that !0.6.2 is worse than Vista (blasphemy!!!) and to tell her boss (Mr Jobs); I was only half joking.

However, it seems this Bluetooth problem is by no means unique to 10.6.0 etc. I've been finding posts about the very problem we're discussing dating back several years. If you google: *"com.apple.Bluetooth.plist missing"* in google you'll see what I mean.

I found some guy with an iBook G$4 who was ******** about the whole Bluetooth issue too although most of the complaints are regarding MacBook/MacBook Pros with early 2008 build dates and beyond.

Hello
when you put the file com.apple.bluetooth.com you must be login on administrator root or a administrator account
the file goes in Macintosh HD/Library/Preferences

and when i reset my SMC i inplug all device there is only my screen and keyboard with mouse but directly on my computer
My computer stay 15 minutes without any cable for empty condensateur i shutdown it
and for the start i do power on stay button on and stop to push when there is the long bip after i reset the pram (alt pomme R P) while (4 gong)

when you go apple menu/ and about this mac/ more info what you mac says on bluetooth ?

My new Mac Pro randomly loses connection with my new two-finger Mighty Mouse (80% battery life). I have to plug in a usb mouse to execute a reconnect. Then, the MM works for a while and disconnects. Is there a fix available, or do I just shelve the new MM as an ultra-modern artifact?

I'm going the latter route.

sdaudet seems to have found a fix that will work for most ( Sfreedm1:scroll up) and has been kindly trying to help me off the forum but to no avail.

As he suggested, I logged in as root to make all the changes he gave me (I had no Bluetooth .plist _at all_ and he kindly sent me his modified pref with instructions to personalise it to my own MAC address).

After switching his MAC addy with my Ethernet MAC, I put it in MacBookHD/Library/Preferences, unplugged all my ports, turned off my machine, waited 15 mins and then rebooted. Still no Bluetooth.

I've also reset the PMU/SMC, I've tried a Terminal on/off utility called blueutil (which wouldn't install anyway -probably because it's not 10.6.0/2 compatible yet) and I've tried to 'overwrite' the BT software by using a Bluetooth updater. Ironically, it tells me I'm current and don't need it. Meanwhile, my System Profiler says *"no information"* when I highlight Bluetooth.

The fact that I didn't have a BT .plist to begin with (apart from a mystery com.apple.Bluetooth pref with a string of numbers instead of the .plist suffix in MacBookHD/Library/Preferences/By Host) suggests that my MacBook can't even find it. However, I know it's there and I know it's a new module because a friend at Apple put my current machine together and specifically noted that it was a new Broadcom module.

Maybe I need to strip down my rig and check that the antenna is seated correctly (as has been suggested on other Mac forums).

Also, after I googled "missing com.apple.blueooth.plist" and "Bluetooth + problem + Mac" it looks like this isn't even a Snow Leopard specific problem. The more I've been looking into this issue, the more I'm seeing that this has been a bug that goes back to early OSX days. I found one from someone with a 2003 iBook G4 that had the same problem.

I'd go to a Genius Bar but it's about two hours away on a bike and I've a bum knee. I'll probably call Apple try and push the Apple Store for a refund and see if they suggest a fix. I'm sure they'd rather help me troubleshoot than take it back.

If not, I will throw in the towel and just use my Mighty Mouse as a paperweight. At this point I feel like Don Quixote with OCD.

Whilst wasting another day obsessing over this, I stumbled across something about a pref called com.apple.blued.plist in System/Library/LaunchDaemons. I took a look with PlistEdit and it certainly looks like it may be involved. It's a Bluetooth pref for sure but I'm not brave enough to experiment with it though.

What do you think Stephane?

hello
i read your message and i found a mistake
When you say that "After switching his MAC addy with my Ethernet MAC", you mustn't put your ethernet mac adress but mbluetooth mac adress you can found it on your old bluetooth preferences
For me the other preferences is for start services...
For the bluetooth available i think it is a corruption cache .....
