On OS X the Packed Pixels display won't automatically show up as "Retina" or "HiDPI" resolution, instead the OS will use the full resolution of the display making everything tiny. This can be changed using the 3rd party app (non-free) SwitchResX.

First, download SwitchResX.

You can play with the resolutions for the Packed Pixels which is probably listed as Color LCD (2). However not all of the HiDPI resolutions work due to an OS X bug. If you are happy with any of the ones that do work then stop here, else continue.

If you're on El Capitan or later you need to disable System Integrity Protection (temporarily) to add a custom resolution for Packed Pixels. Follow the instructions from SwitchResX creator.

Now add a Custom Resolution that is "scaled". It must be 2 pixels bigger or smaller than the native resolution in one direction (this is the OS X quirk). I found bigger makes it slightly blurry so go w
