I cannot turn Bluetooth off on my MacBook Pro. I am running 10.7.4 and the option to turn it off is grayed out, both in the toolbar and in System Preferences. I used Onyx to reset permissions but to no avail. Help, please! I am not using any Bluetooth devices and I'm not sure when or how it got turned back on, but I've always made sure it was turned off. My battery is paying the price!

just to confirm - your account has admin rights? – JW8 Jul 17 '12 at 23:36
That is correct, it does have admin rights. – Jose Jul 17 '12 at 23:44
I had the same issue, it will turn on and won't let me turn it off. After a couple of reboots, it turns itself off and everything is back to normal, no more grayed out options, everything works like nothing ever happened. It might be a bug in 10.7.4. – de_an777 Jul 18 '12 at 14:36

If the issue is corrupted bluetooth preferences, which is my best guess, the following should fix it:

Move the following files to your desktop:

/Library/Preferences/com.apple.Bluetooth.plist
/Library/Preferences/com.apple.Bluetooth.plist.lockfile

Restart your Mac.

This will force your Mac to forget all it's Bluetooth settings so you will have to re-pair all your devices.

..oops, I have the following: com.apple.BluetoothAudio.plist; com.apple.BluetoothFileExchange.plist; com.apple.BluetoothFileExchange.plist.lockfile; So I see the lockfile, which one for the first one you listed? Btw, thanks for helping, really appreicate it. – Jose Jul 18 '12 at 0:34
I don't think any of those files you mentioned will do the trick. Perhaps the issue is that your Mac is not able to create the .plist file due to permissions issues. Can you try to repair permissions from Disk Utility? – AllInOne Jul 18 '12 at 0:45
I repaired permissions with Disk Utility and then restarted the Mac. I went back to the library and no luck with those plists. Bluetooth options still grayed out. – Jose Jul 18 '12 at 1:38
