Hi everyone First of all sorry my English. I wonder if anyone can help me. When you first unbox a MacBook Pro (mine is a retina, but I'm certain that is in the air model too) and you open the MacBook itself there is a piece of paper of some kind dividing the keyboard from the screen. I would always close my MacBook with that piece of paper in place, but since I got it its getting a bit old. Does anyone know how it's called? I will then try to find a decent translation, so I can buy it here. Thank you for your time.
