I just purchased my first Macbook pro and it is the late 2012 with retina display. It came with 128gb of SSD and I also purchased the 480(512gb) replacement from OWC. Just wondering what the actual correct size pentalobe screw driver I would need is? I have looked multiple places and each time I get contradicting answers. The OWC website recommended a tool kit which came with the p5 size, while I read a few places that the newer Macbook pro's with retina from late 2012 took a p4. Let me know if you have any experience with this, below are a couple of the links to what I am finding that say they are compatible.
