Hello, I just was just wondering if anyone here has had an issue with their MBP screen similar to mine. My retina MBP is covered with these white spots and I've noticed this since I first bought it. I have had it for 3 months and now more are appearing on the screen and there are lots of them. The best way I can describe it is they look like a mini iSight camera, or snow! I have tried cleaning it with the cloth which came with it but it does not remove them. I have spoke to support and they said I should take my Macbook to the genius bar and have gave me an appointment. But I had a question about this. If I take it to the genius bar and they discover I need a screen replacement, would there be a big upfront cost for replacement on the day? I've heard screen replacements for Macbooks aren't cheap. Mine is under warranty though. So has anyone else had a similar problem and is going to the Apple store the best option? Thanks!
