Today when I was using my MacBook Pro (13"/2012), and I noticed something odd. On the right side of the trackpad, right at the edge, there is an "arch" that looks like the metal may be distressed. I have tried to rub it with a cloth and some water, but it will not go away, so I'm wondering if I should take it to the Apple store. It also occurred to me that it may be from me being right-handed, and that's where I rest my hand, but just putting my hand there can't do this, right? Someone please help.
