MacBook Pro Lower Case cracks.
Since I opened my MacBook Pro without Retina-Display 2012, the Lower Case cracks, if I press the upper and lower Case together.
What can I do to solve this problem?
Should I solve the screws a bit or should I thighten those screws?
Thanks!
MacBook Pro (15-inch, Mid 2012), OS X Mountain Lion (10.8.3)
