Interestingly enough, Apple is starting to approve Mac apps that include Retina graphics. We are just a few days away from WWDC, where we expect to see the MacBook Pro pick up a Retina display, a first for a Mac computer. This morning, FolderWatch version 2.0.4 was approved and released on the Mac App Store, listing Retina graphics as its headline feature. You can download it right now for $11.99.
