> The fact that smaller text would be crisp and readable on a retina display may have encouraged you to zoom out more than you might do on a lower resolution display though, so the retina display isn't totally off the hook as a contributing factor. Thanks for the reply, yea I think this is the most likely culprit. Though, looking at the font size of Xcode right now it doesn't seem to be any smaller than this text I'm typing on my 20" monitor. At one point a year into working on the macbook I thought it could have been the brightness so I did change my Xcode background to black and used a program called 'flux' to reduce my screens brightness but it really didn't offer much relief.
