In order to reduce glare for its various displays, Apple uses anti-reflective coatings that should absorb, interfere with, and redirect reflected light rays while allowing transmitted light emanating from your display to pass through to your eyes. As with any material that is adhered to another, this coating may strip off under certain conditions — including extreme heat or cold, uneven pressure, warping, and cleaning with caustic agents — things generally well beyond the intended and supported use of your Mac.
However, owners of some Retina MacBook Pros sold since mid-2012 are reporting that the coatings on their displays are progressively peeling under normal use. When this occurs, the systems show what appears to be light-colored stains on the display. Since the coating is translucent, the separation can’t always be easily seen in dark conditions with the display on, but it’s more apparent when the display is turned off in a bright environment.
Apple ha risposto a chi ne ha chiesto la soluzione in correntezza commerciale che si tratta di un qualcosa di “purely cosmetic“.
Ora bisogna vedere se si riferiscono al prodotto o a difetto.
