Apple confirmed this week that MacBook Air models with retina displays may have anti-reflective coating problems, as stated in a memo shared by Apple Authorized Service Providers and obtained from MacRumors.
"Retina displays on some MacBook, MacBook Air, and MacBook Pro computers may have anti-reflective coating (AR) problems," the memo says.
Apple's internal service documentation for this issue previously only mentioned MacBook Pro and no longer available 12-inch MacBook models with Retina displays, but the MacBook mentions air is now mentioned in at least two places. Apple added a retina display to the MacBook Air in October 201
Apple has a free internal repair program for the anti-reflective coating problem. MacBook Air models have not yet been added to the list of eligible models, although mentioned elsewhere in the documentation. However, since Apple at least acknowledges that the MacBook Air may have the problem, customers may have a valid case for at least one free repair within the warranty.
The permission list remains the same as in December 2019:  MacBook Pro (13-inch, early 2015)
Apple started the repair program in October 2015 after some MacBook and MacBook Pro users had a problem with the anti-reflective coating that wears or peels off Retina displays. Apple has never released the repair program on its website and instead decided to make the matter quieter. Because of this, your mileage may vary.
Over the years, the problem resulted in an online petition with nearly 5,000 signatures, a Facebook group with over 17,000 members, and complaints in the Apple Support Communities, Reddit, and our own MacRumors forums. A so-called "Staingate" website was set up to share photos of affected Mac notebooks.
Apple stores outside of China and many Apple-authorized service providers are currently closed, but customers can visit support.apple.com for service and assistance.
