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.
