So I have had to bring in my 15" MacBook Pro from 2015 (Top specs) 4 times so far since I received it last November. It's crazy. The computer will freeze and halt, or it will allow me to move my mouse but not have any clicks register. I have 2 other friends with the exact builds, and they've experienced it a couple of times as well. Every time it's been sent to the depot, I get a report saying that they reported that the logic board was faulty every single time. I had the same issues with the 2012 model for 6 times before they decided to replace it. It's insane, but I'm pretty sure Apple will issue a repair extension program for the 2015 models (Not sure for the 2014 models since I don't own one, but if it persists in 2015, why not in 2014). When I brought in my computer in the Apple Store yesterday, the representative at the genius bar commented how he had the exact same model, and how he had the exact same problems. It's ridiculous how ****** Apple treats not only the "pro" market, but those who want higher end computers in general. It's obvious at this point that they want to push forward with the iPads and MacBooks, while slowly cutting away the "pro" market that made Apple in the first place. If you guys have this model (I'm not sure if the one with integrated graphics only is affected), I would be wary of these problems potentially on your devices. I installed OS X from ground up 4 separate times on this computer, 6 on my 2012 retina MacBook Pro. Each came with the result of it being a hardware issue, and not a software issue. Get your **** together, Apple.
