I have a Photoshop Action set up that takes a History Snapshot, then scales
to 200%. That means, previewing at the Retina display’s resolution is only a
click away. If you’re feeling confident you’ve built everything well, you
should be able to scale up, edit, then scale down and continue editing
without degradation. If you run into trouble, a Snapshot is there to take you
back. Using one document for both resolutions, means not having to keep
two documents in sync — a huge advantage.
