Okay, so I have also tried this on my iMac with the same result, there was only one instance where it booted up and during the loading screen it switched from 1/4 window to the full proper size, I have no idea why and I cannot recreate this. I have tried changing my screen resolution with no success. I have also tried completely deleting the Visual Productions folder and starting fresh, same result. Both of these Macs have retina displays. I have attached two screen shots, one with standard resolution and one with the display resolution set to a smaller size (It just cut off the cuelux window).
