I have an Apple Wireless mouse with a 15 Al PB. Everything was working fine till off a sudden, the mouse doesn't move the pointer anymore. If I turn it off and on, it pairs fine but after that the red light goes off and I can't move the pointer. Weird thing is that if I move the pointer using the trackpad, I can still use the mouse for clicking, but not moving the pointer. So it's as if it's lost it's sense of movement. Anybody have any ideas about this ?
