So, after a while my otherwise perfect (LG screen!) rMBP started creaking. The pattern is usually that once it gets warm, if I lift it up, holding it just with one hand on either side, it'll creak once or twice, then sort of settle and it wont creak again unless it's gotten significantly cooler. Nothing strange about that pattern, metal does expand from heat. And every other unibody MBP I've owned has been the same, just to a smaller extent. I'm not even annoyed by it. But since it does creak quite a bit and since I know some of you folks have taken your rMBP into service because of this, I was just wondering if there's any reason to do something about it, except if it annoys you? I mean, can anything get mechanically damaged if you just let it creak? I would guess: no. But seeing the amount of posts making a big issue out of this has me wondering if I'm wrong.
