MacBook Pro Retina 13": change resolution to 1920x1200 pixels

How can I change the resolution of my MacBook Pro 13" Retina (Late 2013) to 1920x1200 pixels?

The MacBook is able to use this resolution! It's e.g. using it, when connecting a second display which uses 1920x1200 pixels and checking the 'mirror displays' option.

You can use Retina DisplayMenu, QuickRes or SwitchResX.

The built-in display should have a native resolution of 2560x1600. So it should support 1920x1200 @1.3x.

You can use the displaymode command line tool to change the resolution.

Download the binary from the "releases" section, and extract it if necessary. Then from Terminal.app, cd to the directory the displaymode file is in. With any secondary displays unplugged, run:

./displaymode t 1920 1200
