Hello, I have an Early 2011 Macbook Pro and installed a new SSD replacing the original HD with the iFix it kit: MacBook and MacBook Pro (Non-Retina) SSD Upgrade Bundle. I also installed the old HD in a case and have a cable hooking it up to my computert which is the only way, now, for me to get the OS to work. I have tried to turn on the computer without the old HD hooked up via cable, with cmd opt+R and, cmd opt SHIFT +R and a gray screen with a lock and password bar comes up. I have tried ALL passwords I have ever used and the screen will not progress to the spinning globe, just keeps asking for a password. Should I try the cmd opt+R with the old HD hooked up via cable? Thank you

Great guide! The screws that hold the bottom plate on are perpendicular, not the the mass of the plate, but to the part of the curve of the bottom plate. So the tangent of the curve is perpendicular. Your directions are easy enough to understand, for sure. Gave me extreme confidence!!!

How do I plug the enclosure into a computer? Are there cables? Thank you.
