I've had my Magic Mouse working great in Lion with my D-Link DBT-120 dongle. Now i've moved to Mountain Lion, it can't find my Magic Mouse.
At first Bluetooth in general wasn't working well - the icon showed, but it couldn't be switched on and off, so I replaced the IOBluetooth* kexts with the ones from Lion. Now I can switch Bluetooth on and off, but bluetooth devices don't seem to be found.
I also tried replacing the AppleHIDMouse.kext with the one from Lion, as I see it contains a bluetooth mouse kext. That didn't help.
Does anyone have their D-Link dongle working with Mountain Lion?
I have a cloned version of my Lion instance of OS X, can you suggest anything I should copy over from there into Mountain Lion to get this working?
