So my 2015 15 inch retina MacBook Pro stop working little while ago. Symptoms were that it wouldn't power up or boot at all. I took it into the genius bar where they opened it and found that - of all things - a slug had decided to attack my laptop! By the look of it a baby gastropod had somehow found its way into my Computer and subsequently become fried on the circuitboard! Here we come to the difficult bit, as the insurgent has been classified as a "contaminant", Apple are refusing to even consider repairing the computer. I understand that it would probably outside of the scope of AppleCare but they won't even look at doing a paid job Here the parts that seem to be affected could anybody give me an idea whether getting a third-party repair of this might be economical?
