no bluetooth

HI Laura,

Check System Preferences/Bluetooth. You can re pair Bluetooth devices from that pane.

(System Preferences is located in your Applications folder)






Carolyn 🙂

I've had this problem in the past and this fixed it for me.

Go to: Macintosh HD>Library>Preferences and delete the file com.apple.Bluetooth.plist

Do a restart and and you'll probably need to re-pair your Bluetooth devices.

the same has just happened to me on my iMac 27" core i5.
I trashed the prefs and nothing happened. The bluetooth preference pane has disappeared from System preferences. My one year warranty ends in 5 days. It's off to the apple store I go.

Hi Simon,

This morning the exact same thing happened to me, no Bluetooth preference pane, no Bluetooth info in System Profiler, no menu icon, no Bluetooth anything. I have a USB mouse and keyboard so I could work. I have AppleCare and called Apple. The tech said to do a Safe Boot (boot while holding down the shift key.) Bluetooth started working, but my airport was now off. Then I reset the SMC in the iMac by unplugging the power cord and holding down the power button for 5 to 10 seconds. This cured the problems. Maybe this will help you. Hope so.

HiOld Pal,

exactly the same thing happened to me this same day on the same machine and I eventually solved the problem in exactly the same way: First re-booting the safe way with shift pressed -- the AirPort Card was reported as having got lost and no Bluetooth was available either; then I did the SMC resetting (the way you find it recommended in the knowledge base http://support.apple.com/kb/HT3964 ) and an additional unplugging of the machine -- and !milagro! !miracle! Bluetooth showed up again in the system preferences such that I could connect and use again the magic mouse.

What a pity that I did'nt read your comment earlier. I did a short and a long hardware test (all was reported as being OK), reinstalled the system -- no use either.

So thanks for participating in your positive experience.
Kindest regards from Old Europe

Hi Old Pal and lahjakas,
I did the same thing, did a reboot in SMC and bluetooth came back for me too. Very happy that certain things can be solved quite easily on a mac.
Cheers.

Glad to be of help to you all.

Paul_31,

Today my bluetooth mouse was not discoverable. You suggestion to delete the file "com.apple.Bluetooth.plist" and restart worked for me.

Thank you very much for your contribution to this forum. Would give you a star if I could 🙂

Hi, the same problem happened to me. I've tried everything you guys said, it's still not working....... Any other ideas? Thanks so much!!

My 21" i3 iMac that I got today also tries to tell me "Bluetooth: Not Available". I've also tried all the things described in this thread and have not had any luck. Does anyone have any suggestions that don't involve me having to fight the crowds at the mall tomorrow to get to the Genius Bar on the day after Christmas?

Same symptoms. No Bluetooth (Not Available from Menu Bar & No Information in System Profiler) on the 27" iMac i5. Safe Boot first, but Bluetooth did not return. The SMC reset did bring it back. Re-connected Magic Mouse and Keyboard.

Thanks for the help.

Thank you lahjakas! I got the exact same issue: after upgraded to 10.6.6 this morning, the iMac was fine for a while then all of sudden the bluetooth is gone from the iMac. Not in System Profile nor Preference. Glad that I found this thread and use lahjakas's safe mode reboot and SMC reset sequence now the bluetooth went back!

Resetting the SMC did the trick for me too, cheers!

A reset worked for me but a week later I had the same issue. This is NOT acceptable for a brand new iMac. No Apple store here so I took it to a local authorized repair place where, of course, it worked perfectly. Any suggestions?

Same problem here. Brand new 27" i7. But safe boot and resetting the SMC worked. Thanks Old Pal and Lahjakas
