Problem: Problem med skruv i MacBook Pro Retina 13'' Late 2012

Jo då, redan 2009 har vissa Macbook haft det: "
The first Apple product to include pentalobe screws internally was the Mid 2009 MacBook Pro 15-inch model. Three pentalobe screws were used to attach the battery to the internal frame. A 1.5 mm flat-blade (slotted) screwdriver could easily remove these screws, which were originally mistaken for 5-point Torx screws.[3] This was the only internal usage of pentalobe screws; all following MacBook Pros use the "Tri-Wing" security bit to attach the battery to the internal frame.

Pentalobe screws reappeared in the mid-2012 version of the MacBook Pro. Eight 3 mm and two 2.3 mm pentalobe screws were used externally to attach the bottom plate of the case to the internal frame.[4] The late-2012 version of the 13-inch MacBook Pro was the first 13-inch model to have pentalobe screws; several were used externally in a similar fashion to the 15-inch mid-2012 MacBook Pro.[5] None of the three 17-inch models of the MacBook Pro have used any pentalobe screws."
