Ok so i noticed this the other day, there is a mark on my 2010 macbook's (white) screen at first i thought it was a smudge but it turns out its some sort of mark from pressure being applied to the screen. I guess its called a pressure mark. It may be from closing my macbook because there is a small curricular mark and a long strait one, presumably the straight one is from the lip under the keyboard and above the trackpad. So basically i guess i am asking, what do i do, will the problem eventually go away, or will the screen need to be replaced?
