A:AnswerIt fit the 2015 Mac Book with retina fine, the problem is the cover itself isn't very durable. I still have the top part of the shell covering my laptop but the bottom half was shot to pieces a few days after putting it on my mac book.
A:AnswerYes. But make sure you get the one for the new 2106. The one for the older model is in a nearly identical case
I got the wrong one the first time.
A:AnswerMy case has stress cracks on the corners and I have never dropped the case or done anything to cause it to crack. It also scratches very easily.
A:AnswerThe Speck one covers the edges and corners, the less expensive ones (Insignia) are thinner and don't cover the edges and coners as well or at all. The edges and corners take a beating on a laptop being used heavily. Plus, if you ever damage/crack/break a corner on the Speck they will send you a new one, I think up to 1 a year.
