UPDATE 2: Apple has called me and they have not been able to replicate it. The woman explained that it passed all they're hardware tests and she believes that the issue lies with something related to my data. Maybe a program with bad code or something else corrupted on my drive. She even mentioned replacing my computer but she believed I would have the same issue with it again if I restored all my data to it. While I'm disappointed, I do understand that they simply cannot replace a computer without evidence of an issue. The sad thing is that I truly believe it will FAIL entirely within the 90 day depot warranty due to the awful replacement boards they are putting in these machines. UPDATE: I had my appointment and the result wasn't exactly what I was expecting. I wasn't able to reproduce anything for the genius in person so he insisted he keep it for a few days to run extended diagnostics on it before he decided what to do. My fear is that they won't be able to replicate it and will tell me there's nothing wrong with it. The last 2 times I had proof in pictures and screenshots. This time I do not have that since it happens for only a split second at a time and then goes back to normal. OP: I posted about 2 weeks ago about how upon picking my computer up from it's second repair the genius said, "If you have any issues, be sure to bring it back and we'll get you a more permanent solution." I'm on my third logic board now and I'm already seeing occasional graphical glitches. I called apple today to explain my frustration. The rep told me I would need to take it to the genius bar but he did leave me one nugget of hope just like the genius did. The rep explained that during my visit, it would be very possible that they would replace my MBP with a similarly spec'd computer. I replied with "what, like a new or refurbished 2011 model?" He hesitantly said "something like that" He was clearly being vague on purpose and he probably couldn't get too detailed without risking getting himself in trouble. Anyway, the point is, if you have a 2011 15" or 17", be diligent but polite and you may eventually get yourself a replacement machine.
