How do I fix "Bluetooth: Not available" I have a 2012 15" MacBook Pro and the Bluetooth is "unavailable". It has been like this for a while actually, probably about a year and a half. Sometimes it randomly becomes available and turns on only to become unavailable again only minutes later. Also a Bluetooth setup wizard app opens sometimes, usually after I turn the computer on after it had shut off from low battery, but when I click on it nothing happens. I haven't cared about this issue too much because I didn't have anything connected using Bluetooth, but now I actually do have something that I want to connect. I have tried resetting the SMC, deleting the .plist file and restarting, but neither of these worked. Does anyone know what might solve this issue?
Delete Bluetooth paired list
Close any Bluetooth associated file that may hinder the process
Copy/Paste following and Press the combination Command + Shift + G

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


Rename it so to save a copy com.apple.Bluetooth-Old.plist

Now delete the original file and restart your Mac, it should create new Plist.

Alternative approach

Press ⌘ Space to activate Spotlight.

Type "bluetooth", choose the 'Bluetooth File Exchange' application, and press Return.

Bluetooth File Exchange will prompt to enable the bluetooth hardware, press Return.

Bluetooth is now enabled and you can quit Bluetooth File Exchange.
