Greetings from Cleveland,Ohio. This is my first comment,and it is in reference to my barely used,late 2013 Macbook Pro.15" Retina display,256,SSD,8gigs of Ram. The only thing that was used less than the laptop,was the Trackpad,that now needs to be replaced,and after seeing this Guide,I either pay Apple 300 bucks for a whole new top,which is what the Apple store people told me I would get with the repair.Obviously,that's the only way that the Trackpad can be replaced. I'm new here to this website,and very happy that I found it by mistake. Thank you very much for the info on this piece of !@#$ computer.My only regret is that I didn't find you before I bought the Macbook,because I never would have purchased one. I will never purchase another Apple product. Cheers!
