So I've had my rMBP for about 5 months now and really have had no complaints...Until Now! For some strange reason I can feel and hear something rattling around inside both the left and right sides of my computer? To me it basically feels like something is loose and not held down correctly. Anyway I made a genius bar appt and brought it to apple today and wow I would have never guessed...The genius opened it up and said nothing is wrong and that what I'm hearing are the fans moving around because they have springs and have play? For some reason I just don't buy that, almost a $2k lap top and the fans rattle around inside? And this isn't a problem from jump street, it just started happening. So can anyone chime in here and shed some light on this subject.
