I bought my rMBP, 2.6 GHz Quad, 16 Gb RAM, 512 Gb SSD before Christmas, and was very happy with it. (For the layman, that's an Apple Mac Book Pro, with a display made from real retinas, 2.6 litre, 4 wheel drive, with 16 Gazillion Bytes of Radio Active Memory, and 512 Gazillion Bytes of Sheet Steel Disks. I read the Image Retention threads, and was doing well until last night, when I gave in and tested my Mac. I checked the manufacturer of the retinas, and it was LG. I checked for dead pixels, and found none. Then I turned the brightness up to maximum, and did the Image Retention test.... After 10 minutes, the chequerboard image switched over to a grey screen, and there it was! Image Retention! Oh my god, what am I going to do!!!? At the same moment as I cried out in anguish, my friend looked at my screen and was puzzled. He confirmed that my beautiful Retina display was absolutely fine, and had no image retention. I was confused, until I looked away, and then I understood... MY EYES HAVE IMAGE RETENTION!!!!!! Help me, please!!! Can I get new eyes from The Apple Store? Should I take them back right away!? I don't know what to do!
