There has been a growing number of users whom have turned to the Apple Support Communities, MacRumorsdiscussion forums and Facebook in recent weeks to voice their issues, specifically on complaints about the anti-reflective coating on Retina MacBook Pros seems to be stained and looks like it is wearing off. This display issue appears to affect several MacBook Pros, including batches from mid-2012 to mid-2014 models sold between June 2012 and present.
Anti-reflective coating wears off under a variety of circumstances, which includes the exertion of pressure on the keys and trackpad on the display when closed, and the usage of third-party cleaning solutions and microfiber cloths. Although this issue limits to small areas on the screen, there are users whom shared pictures of the entire anti-reflective coating wearing off across the entire display.
There have been mixed response from Apple. While some users are able to have their repairs covered under the standard one-year limited warranty or AppleCare Protection Plan with no charge, other users have been informed that cosmetic damages are not covered and have been offered to have it repaired at a fee, which costs hundreds.
