what kind of screwdriver to open macbook pro
Pentalobe security screw The Pentalobe security screw[1] (Apple nomenclature), or pentalobe screw drive, is a five-pointed tamper-resistant system used by, among other companies, Apple in its products.[1] Pentalobe screws were adopted by Apple starting in 2009, when they were first implemented in the 15-inch MacBook Pro. They have since been used on other MacBook Pro, MacBook Air and iPhone models. Apple attracted criticism upon the introduction of the pentalobe screw; it was seen by some as an attempt to lock individuals out of their devices.[2] Inexpensive pentalobe screwdrivers, manufactured by third parties, are relatively easy to obtain.[3]
