Hi I have a 13 retina MacBook Pro and took it in for repair today at my apple store. It has a bad case of ghosting. When I was sitting with the genius he did their screen ghosting test and it passed. He said he would take in for for further tests though. Anyone have any experience with this? Any tips on getting it fixed with them? I have a feeling they are going to say, sorry passed our tests, 'it's a software issue that will be fixed in future'. I know that's nonsense, screen ghosting has existed for long enough to know its not software related. Hope you have some good stories to share.
