Bluetooth completely stopped working

I was working on Friday when suddenly my BT keyboard and trackpad stopped working. I thought it might have just been either the batteries or a dropped connection but nope. I managed to pair those devices with my MBP so know there's no issues with the BT in the devices. So far I have…


- Turned Bluetooth off and on again.

- Removed the devices from my BT prefs and tried to reconnect.

- Removed the BT prefs from my Library

- Repaired disk permissions

- Repaired Disk

- Run Dis First Aid (or whatever that's called now)

- Started in Safe Mode


Nothing I've done has had any effect and so I still have no Bluetooth.


Here's what was said in the Console prior to the blackout…

I've got a replacement on order with Amazon but would love to know what has caused this.

Mac mini, OS X Mountain Lion (10.8.5)
