Bluetooth not available - Mid 2011 iMac
So recently I got a Mid 2011 iMac 21.5" second hand, and I notice that the bluetooth icon on the menu bar had a line through it. It comes on randomly. I have tried every thing I have found to 'fix' this problem and none work perminatly. Any idea how to fix this with out having to take it to an genius bar?
iMac, OS X Mavericks (10.9.2)
