I am on a 2008 Mac Pro. My computer was on and after being in another room for about 5 minutes, I start hearing my music playing on the Mac. My iTunes wasn't even on, how is this possible??? No one here but me, so it's not like the keyboard was pressed or anything the music just started playing. It was a random song too, in the middle of one of my albums. First: has anyone ever heard of such a weird thing? Second: is this of concern security wise? Is someone hacked into my machine?
