[trypto]

hi guys

i bought a new macbook pro retina 2014 a month ago.
And today when i closed it i found that black panel is not tight when i press on it it has a lift closer to the middle. When i open a screen its ok , fits tight !
anyone have that ? how can i tighten it?

i attached photo

on my previous mac i didn't have that problem !
