I have a macbook that is 1 month old. About a week or two ago it started doing this thing: randomly, usually after I've been using it for an hour or so, a voice comes on and says "Question authority, think for yourself" on loop. There's no way to make it stop other than restarting. I'm not connected to any networks and no applications are running. At one point I did use some public wifi networks...when this started, though, I hadn't done that for awhile. All I've installed is Adobe Creative Suite. I also loaded some music from my computer at work, which has no problems; most of that music is purchased. I haven't downloaded any email attachments, applications or anything else that i can remember. any ideas?? I guess I'm going to just reinstall everything but don't you think that's weird?
