This guide was a bit difficult to follow because the photos didn't represent 'exactly' what I was seeing. I was able to find the corresponding connections.
The trouble I'm having is the guide seems to end a few steps too soon. I still have a display inside the upper shell, the piece with the Apple logo. I'm very concerned for the well-being of the 'old' pieces in question. I have to save the upper case piece while extracting the display.
This guide is about the 5th or 6th guide I have used and every one of them is very well constructed and documented, I haven't been disappointed with any of them.
Up until this one I had made do with my own miscellaneous tool assortment, making do when I didn't have the exact driver bit or tool. The tri-wing screws in this one encouraged me to get the Pro Tech ToolKit [producto vinculado inexistente o deshabilitado: IF145-072-1] and now I kick myself for not getting the proper tools sooner. All through my career as a Remodeling Contractor I maintained the attitude of using the 'right tool for the job'. Well, same holds true here.
Looking forward to my next iFixit job. Thank you iFixit.
