Bluetooth Re-Enabler after 10.8.5 Update
The 2 kexts (IOBluetoothHIDDriver.kext & IOBluetoothFamily.kext) are from OSX 10.8.2 with version 4.1.2, they fixed my bluetooth problem for me in OSX 10.8.5.
After last 10.8.5 update these 2 kexts where updated to version 4.1.7, this gave several issues with my internal Bluetooth device on my Lenovo T61 ThinkPad. I wasn't able to use Bluetooth in OSX anymore!!
But these 2 kexts from 10.8.2 worked fine for me!
Drag and drop these two kexts into Kextutility or install manually..
