Hi Pieter, the pixelated Retina display will be fixed in MoI v4. One of the big changes for v4 is that it's now a native build for Mac and isn't using the Wineskin mechanism anymore. Among the various little glitches that are solved is that it uses the native resolution on Retina displays now. The current v4 beta is available to existing users here: http://moi3d.com/beta.htm
