I've had my macbook for just over a month and a couple of weeks ago yellow patches showed up where my hands would rest. when I google this a lot of threads come up about it but nothing that recent so I wanted to ask. what can I do about this? I've tried everything to get the marks off but the only thing that worked were nail polish remover wipes. but these kind of removed a layer of the plastic as well as the marks so I don't want to use them. I have no other problems with the laptop, everything else is great, so I'm kind of annoyed that the downfall is something so little, but it just looks horrible and not like a new laptop. so basically, what works to get the marks off without causing further damage, and if I take this to apple what can they do?
