Restart crashed or disappeared Bluetooth service on Mac OS X

OS X BluetoothRunning relatively stable over the whole time I’ve got my MacBook Pro it occasionally occurs that the Bluetooth service is crashing (as noticeable by the grayed-out B-symbol in the top menu bar of Mac OS X). Clicking on the icon and on „Bluetooth: activate“ uses to ignore me in this situation.

So what can we do? Well, we’ve to leave the convenient GUI and go one step deeper to the black/white, cold command line.

Just run this commands in Terminal (tested on Mac OS X 10.6, the paths can be different on other versions):

sudo launchctl unload /System/Library/LaunchDaemons/com.apple.blued.plist
sudo launchctl load /System/Library/LaunchDaemons/com.apple.blued.plist

The Bluetooth icon in the menu bar should get back it’s black color and the Bluetooth daemon should connect to all devices instantly.

Feedback for other Mac OS X versions is appreciated (just leave a comment).

    Don’t think unloading it twice is likely to be helpful; what would be helpful is if the box the commands is in didn’t have a fixed width and overflow-x: hidden.

    second line should probably be ‚load‘ not ‚unload‘

      Yes, you are right. I’ve corrected the line. Thanks for the hint 🙂
