On a retina display mac, how can I run an application or the entire OS in a non-retina mode?

What I have done:

I have checked this SO question and this SO questionand apple startup buttons I have done many searches leading to dead ends.

What I want:

To run my app to compare differences in rendering quality between retina and non-retina machines.

I thought maybe there is some keystroke when I launch, or some system setting, but I might not know what the term is for this toggle.

  • VMware Fusion has a setting which controls whether a VM sees the full retina resolution or not, so you probably could set up a Mac OS X VM with retina resolution disabled. – Paul R Nov 02 '15 at 14:54

If you do Get Info on an app, you can click the checkbox for "Open in Low Resolution":
