I have a 2008 Mac that hardly ever crashes. But from time to time (not always) it crashes (the whole computer shuts down as if the power has been cut off) when I plug in an Arduino via USB.
What could cause this?
I've done some testing and the constant in when this occurs seems to be a cheap PIR sensor from eBay. It works some of the time.
Should I get another sensor? Or is there something about PIR sensors that makes them prone to this? It has a lot of caps... Is there another kind of motion sensor?
