I have a 13" mid 2010 Macbook Pro running 10.8.3. For some reason, I started it up the other day and my Bluetooth is now for some reason unavailable.
I've had this problem in the past, and if my memory serves me correctly the only way to get it back was just to let it come back on it's own. However, it's very annoying that this happens apparently no reason and this is just not good enough.
I've tried the following:
- Restart, shut down, suspend/resume cycles
- Reset SMC
- Reset PRAM
- Deleted any Bluetooth.plist files in ~/Library/Preferences
- Verified permissions
And nothing has worked. Any suggestions?
