Fixing a “Bluetooth Not Available” Error on a Mac

Trash Bluetooth Preferences & Shutdown the Mac

First up, delete the Bluetooth plist file and have the Mac create a new one:


  1. Close System Preferences and/or any app that was trying to use or configure any Bluetooth device with the Mac
  2. From the OS X Finder, hit Command+Shift+G to summon Go To Folder and enter the following path:
  3. Locate the file named “” and delete it (you may see a too, if so delete that as well) – this is a system folder so you will need to authenticate with an admin user
  4. Head to the Apple menu and choose “Shut Down” to power down the Mac
  5. Wait a minute or so before booting the Mac again
  6. Head to the Bluetooth menu or System Preference panel to resync your hardware

(Note this is /Library/Preferences/ not ~/Library/Preferences/)
