The Bluetooth icon si grayed-out with a sig-saw sign over it. It says Bluetooth not available, and I can not activate it again. Any suggestions?

    I'm just adding a comment to say a SMC reset worked for me.


    About an hour ago I was making a phone call via Google Voice, using my Bluetooth headset when my phone call got cut off and Bluetooth froze (beach ball over the menu bar icon). I tried to restart, but the system wouldn't fully shutdown so I did a manual shutdown. Upon reboot Bluetooth was not available and Bluetooth was completely gone from System Preferences.


    This had never happened before, so I was a bit concerned.  I repaired disk and permissions, then ran Disk Warrior. When that didn't help, I came to the Apple forums, typed Bluetooth into the search bar, and quickly found this thread.


    I followed Apple's instructions for resetting the SMC, and upon reboot Bluetooth was back!


    Since a link wasn't provided in the previous post and I had to search for the instructions, I'm including the link here to help others.

    This was a great fix, thanks for adding the link as well. I applied the work around and that fixed the issue!

    Hello all,


    Thought I'd ask here. I use a late 2008 MacBook Pro 15" with 10.6.8. I use bluetooth primarily for live music performance, controlling sounds and samples with Wii remotes. Since December or so my bluetooth has been showing as 'unavailable' completely unpredictably. I've tried that SMC reset and that didn't help. Sometimes it works fine, but other times it crashes mid performance, and obviously shutting down etc. in the middle of a concert is no good!


    I use a MOTU FireWire audio interface when I use the Wii remotes, and sometimes an Akai LPD8 USB Pad controller. Could either of these affect the bluetooth? I've tried various combinations of no devices, just the pad controller/audio interface etc. but they don't seem to have much influence; if the bluetooth wants to crash, it'll crash. The problem is that, as above, it's totally unpredictable. I'm taking it in to the Apple Store today but I was wondering if anyone had had problems with Wii remotes and/or FireWire/USB?

    I had the same issue.  PRAM reset did not solve it.  SMC reset worked like a charm

    Hi, after resetting both PRAM and SMC, problem didn´t solve.


    After doing those steps, i got this new problem. The name of my computer doesnt show up on Finder. I took a snapshoot to ilustrate the problem.


    Any clue?
