Just wanted to share a positive experience I had with Apple today. I recently bought a used mid 2012 rMBP from another member on here. It worked well for a few months, and then started having the well documented graphics glitches and random restarts that plague some of the 2011-2012 models. I took it to the Apple store after speaking to AppleCare. I did not hold out much hope of anything other than another repair under the extended MacBook repair programme that is going on. I sat with the Genius and explained the issue. He looked into the history of the MacBook and the number/type of repairs it had been through. After a few minutes he called over a female colleague and said a few things to her that I didn't quite pick up. Seconds later, I'm being told that they are going to put this whole thing right and swap the machine out with a brand new, top line 15" rMBP with another year warranty to boot. So, here I am typing away on the 2015 2.5 GHz rMBP. Quite simply, and consistently, Apple provide me with the best customer service I receive from any company.
