iFixit has word that Apple are making it much more difficult to repair your devices by sticking in a "tamper resistant screw":|
It?s similar to a Torx?except that the points have a rounder shape, and it has five points instead of six. Apple?s service manuals refer to them as ?Pentalobular? screws, which is a descriptive enough term. It?s certainly better than what I came up with, which was ?Evil Proprietary Tamper Proof Five Point Screw.? It?s best I stay out of the naming business.Emphasis added.
Contrary to what has been widely reported elswhere, this is not a security Torx screw. Security Torx have a post in the middle. Apple would never use a real Torx security screw with a post for two reasons: they?re ugly, and the posts break off easily with screw heads this small. To further complicate matters, Apple occasionally refers to these as ?Pentalobe security screws.? Please don?t confuse them with security Torx.
This screw head is new to us. In fact, there isn?t a single reputable supplier that sells exactly the same screwdrivers Apple?s technicians use?which is Apple?s point. They picked an obscure head that no one would have. This new screw defeats even our vaunted 54-bit driver kit, which until now we?ve been able to claim that it?s all you need to disassemble just about any consumer electronics. Alas, no more. Thanks a lot, Apple!
