RetinaCapture 1.0.1
Matt Rajca’s RetinaCapture is a neat utility that can simultaneously take screenshots at 1x and 2x (Retina) resolutions. If you have multiple displays, both RetinaCapture’s window and the window that you want to capture must be located on the Retina display. I’ve also found that the menubar must be on the Retina display or else you can’t choose a window; hopefully that’s a bug that can be fixed.
Update (2015-01-30): Unfortunately, the 1x screenshots do not look the same as 1x screenshots taken by the OS. The text is not rendered in the same way and, especially with Yosemite, looks very jagged.
