Im confused about retina resolutions. When i select best for retina for my mbpr 13 inch there seem to be not enough space on my desktop for multiple windows etc.
My question is if i use a scaled resolution to get more desktop real estate am i getting what would be deemed retina quality images. If not why not.
Thanks for your time searched many posts still don't understand it.
The Retina MacBook Pro 13", displays EVERYTHING at 2560x1600, because that is the resolution of the screen. It's always 2560x1600, so you're always getting retina resolution.
Example:

The problem is that running any operating system whether is be windows or OS X at 2560x1600 is that every single icon and app is incredibly tiny. You cannot use the operating system at this resolution on a 13" screen. It would be ridiculous.
So what Apple does is they enlarge the interface, example with windows:

This is called "scaling". The purpose of this is to make the interface operate as if you had a "normal" resolution, so instead of clicking on icons the size of ants, you're clicking on icons that are sized normally.
This is confusing because instead of calling it "2x Interface Scaling", Apple likes to explain this by basically saying "It's going to look like an imaginary computer with the same screen size that has a resolution of 1680x900 with scaling set to 1 ". Except they don't tell you that this is "imaginary" and "like" and "default scaling set to 1", they just say "scaled resolution: 1680x900", which isn't very informative if you don't know what it means.
The options under resolution just change the scaling, and explain the different scaling options in an extremely weird and misleading way they have nothing to do with display resolution at all whatsoever, you're always at Retina resolution of 2560x1600.
Hope that helps.
