    Hello, the area of my mac on the palm rest is getting black, small craters, currently their tiny but I fear their going to grow. I've had this issue on my old mac where in the end there was like a small mine field of black dots. Here is a link I found to the issue

    I wanted to get a palm rest protector but apple advises against it on its websites, I think due to staingate...

    So does anyone know what I'm supposed to do? Does warranty cover this?

    p.s I attached a file I found on google showing pretty much what is happening (currently not as extreme)

    The black spots are corrosion and occurred due to the sweat from your palms. It seems that this affects a number of people but not everyone - possibly due to body chemistry. In any event the only way to stop it is a palm rest. I've not used them so I can't recommend one.
