I have a mid-2013 rMBP 15'' that has AppleCare. Less than a month ago, it started having serious issues with its display and the colors were are messed up. I brought it into the Genius Bar and they determined I needed a new logic board. I received the MBP 5 business days later, and it took me 10 minutes to restart it, it became extremely hot within just 5 minutes, and in the last couple of weeks after its repair, it has froze and shut down on me randomly at least 3x. What are my options? Take it in AGAIN for repair? Do they do replacements? It's becoming quite the distraction as I use this for my main work computer and have lost unsaved portions of work. Has anyone had experience with a repair that isn't to your satisfaction?
