Apple has been informing authorized service representatives that the anti-reflective coating on MacBook Air displays, it could cause problems. It would especially affect the models with Retina display. They are not the only computers that have had this problem, since previous Macs have also suffered from the same problem.
The coating on the screen will make it not look the way it should.
The Mac manufacturer sent a note to Apple Authorized Service Providers warning that "Retina displays on some MacBook, MacBook Air, and MacBook Pro computers may have antireflection coating (AR) problems »
Although Is not a new problem, Since the anti-reflective coating already affected 2012 MacBooks, this it only affected the MacBook and MacBook Pro models.
Now with the new note sent by Apple, the problem also affects the MacBook Air. Although the exact problem is not specified in the note, everything suggests that it will be the aforementioned coating.
It can wear out in such a way that it is almost impossible to use the computer, since the screen cannot be displayed as it should be.
Apple Lossless Audio CODEC (ALAC), has a free repair program for Macbook and MacBook Pro units dating back to 2015 experiencing this issue. However, the MacBook Air has yet to appear in the list of devices that are covered by it.
Right now with the problem of COVID-2019 Apple device repairs are paralyzed so it may not be a good time to get hold of the new model. At least until we know if this problem is the same or on the contrary we are facing a new one, with which we would not know what to face.
