Perfomance of the editor on my mac book pro retina 15'' is horrid

I just subscribed for the first time to unreal engine 4, and i downloaded the editor, and i got to say, am quite disappointed with the performance, my fans are going crazy and my mac is heating up and am barely getting 26 fps on a simple project, i turned off the launcher and closed every open application, but still the performance still sucks, also the quality of the editor is terrible i can almost see the pixels of the buttons and characters on my screen, is it a common problem, when there will be an update for retina mac users.

same case here. Is it because of the retina display?
