Hi Kloper, first thank you for your guide. I just wanted to make you notice that in your first post, the guide, you say that there is a different config for a 15" retina/non retina macbook and that it is (described here), but there is no link, and in the guide you have not written it. It would be nice, if you had time, if you could post it. Thank you very much for your attention. Coseno PS if you are wondering where is this thing I'm talking about, it is found in the section "requirements"/13"retina macbook pro, first page of the thread, first post. Peace
