So its been a week since my one year warranty expired and i have a cracked palm rest that stretches alongside the entire left hand side of the trackpad on the macbook. It looks really bad. I've gone through two case replacements and even saved the receipts and this will have to be the third time. Few questions: 1. Will Apple replace the case out of warranty, especially if i show proof i've had to repair it several times. 2. Does Apple do anything after multiple cracked cases? (i.e trade in for new macbook anything of that sort?). 3. Is there a way to prevent future cracked palm rests.
