As we show in this screenshot, Apple redesigned the Displays preferences panel on the new MacBook Pro to make it easier to configure your Retina display.
The standard configuration “Best (Retina)”, which makes the machine run at 1440 × 900 pixels with clear HiDPI mode. If the user selects "More Space", loses a bit of sharpness but has more space at 1920 × 1200 pixels.
Note, however, that Apple does not allow, by default, the user to choose to run the machine in 1: 1, that is, each pixel occupying its total resolution of 2880 Ă— 1800 pixels. That's because everything on the screen becomes very small and probably few people would like to work like that.
Here is the configuration “Best (Retina)”:
Here, the machine actually running at 2880 Ă— 1800 pixels:
To be able to make this change, I need an extra utility developed by third parties like SwitchResX or Change Resolution. There are others that do the same thing, but it's important to note that OS X doesn't offer that option. Interestingly, anyone with Windows via Boot Camp can configure it that way, according to their preferences.
As a regular user of a 17-inch MacBook Pro with the native resolution of 1920 Ă— 1200 pixels, I would not mind migrating to one of the new 15-inch ones with that same resolution. Everything would be a little smaller (and clearer) for me, but it certainly wouldn't be as drastic as going to such 2880 Ă— 1800 pixels.
