The high-definition Retina display on newer MacBook Pros is supposed to be one of the laptop's major selling points. But, the screen's anti-reflective coating is causing major headaches for Apple and frustrating users.
So, what's up with the display? Several factors are causing the anti-reflecting coating to wear off, causing blotchy stains across the screens. This could be caused by a lot of different things like third-party cleaners or the pressure put on the screen by keys when a laptop is closed. However, some users have reported the issue popping up after they cleaned the screen according to Apple's directions.
Right now, it looks like problem is affecting 2012 to 2014 MacBook Pros sold between 2012 and now, according to MacRumors.
