Today I noticed the trackpad on my 15" rMBP wasn't fully pressing down when I click on the left side. Overall it is still responding to input, but the travel of the "click" is shallow. It wasn't like this before, and is worlds apart from the right side of the trackpad which still making a satisfying sound when you press down. I've spoken with AppleCare and they've just said I should make an appointment, which I can't do for the next 6 days or so as my local stores are fully booked. Anyone have any experience with something similar?
