How can I erase Bluetooth devices on my Mac I had an bluetooth audio device (Bose SoundLink Wireless Mobile speaker) remembered on my MacBook Pro running OS X 10.8.5. Now I don't have it anymore and I want to link it with another audio device and it seems to be unable to forget the Bose one and link with my current device, how could I erase the Bose device?
In System Preferences > Bluetooth, make sure that Bluetooth is on and the Show Bluetooth in menu bar check box is checked. Then hold down alt or option before clicking the Bluetooth toolbar menu icon.  Now, in the device's contextual menu you can remove it.
