My Macbook Pro Retina has what looks to be 4 dead pixels and I'm thinking about getting it repaired/replaced at the Apple Store. I've had it for about 2 months. How does the process work? Do they repair it in the shop or do they ship it off to a repair center? Will I be out of a laptop until the replacement comes? How long does it take? (My rMBP is the base model with no customizations). Will the replacement be shipped to the Apple Store or will it be shipped to my address?
