Unity3D Retina Display iOS Development Issues (GameView)

Hi,
I am working on an app that I have built entirely for the 1024x768 iPad resolution. The people I am working with want me to scale everything up to retina (2048x1536). I realize that you can just upscale it when you compile it but the issue with this is that all assets are aliased.

ISSUE:
I need to work in the game view for the app and the highest resolution my laptop screen supports is 2560x1600 meaning I do not have enough room to see the app (and Unity starts cutting off assets). Is there a way to work with the ipad retina resolution at my screen size? I know in some programs you can use a magnifying glass type tool to zoom out. Or Maybe I can get rid of that top toolbar?
