Well, my display came with the standard LCD calibration, so it had like this white hue, you know? So being a retina display Ithouht it had to look better. I looked up in the web and found how to do the expert calibration (pressing Ctrl or option whilst calibrating),
The picture I posted is an example of what I did, the pic is from the web but looks exactly as my display now.
I'm sorry, I'm new at Mac, I don't know what Sypder3 is.
