Earlier in the year, a small-but-not-insignificant number of Apple customers complained about screen issues with their new Retina MacBooks and Retina MacBook Pros, specifically cases where the anti-reflective display coating leaves marks and stains on the screen, ranging from small corner blobs to large patches.
Several months later, Apple seems to have acknowledged the issue and launched a Quality Program to replace affected users’ hardware. The Staingate Facebook page now includes many reports of people successfully sending their MacBooks in for repair at Apple Stores. The existence of the program was first reported by MacRumors.
In general, though, it seems Apple is trying to keep news of the problem quiet. There is no public acknowledgement of such a program existing on Apple’s website. Apple is contacting people who have reported the problem earlier in the year and were turned away, however. If you have problems like those shown in the picture above (although that’s an extreme case), you should now be able to take your laptop to the Apple Store for a straightforward repair.
AppleCare coverage is not necessarily required with several people successfully getting screen repairs/replacements who are officially out of warranty. If you believe you are affected by this problem, call Apple Support or visit an Apple Store or authorized reseller for support.
