Hey everyone I bought a 15" MacBook Pro retina around thanksgiving time. Lately I've been noticing a rattling noise and figured out it's the trackpad. One side is sunk in and you can lightly tap your finger on it and see it move/rattle. I called best buy and I can exchange it. Would I be best off exchanging it or just taking it in to apple? I have a time capsule, but spend a lot of time setting this up. Thanks!
