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!
If the issue is corrupted bluetooth preferences, which is my best guess, the following should fix it:
Move the following files to your desktop:
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.
