Summary: With a small body, insufficient venting, high resolution display, this retina version MacBook pro is fested with Overheating issues. I am very surprised that nobody is mentioning this big problem here while a Google search of "MacBook pro retina heat problem" returns thousands of hits. Two remedies are discussed by suffering owners: 1. Get ride off Chrome browser, which causes many background processes. 2. Uncheck automatic switch on/off the dedicated graphics card.
