Responsive for Macs, how to do it?

Question

Adaptive design

I ran into such a problem, for example, at a resolution of 2560x1600 on a poppy, the layout starts to move out, although if you set such a resolution in chrome / mozilla in adaptive design, then everything will be ok. I know that on poppies the scale increases by itself and shows, for example, 120-130%, but how to catch certain scales through media queries and, in general, how to make an adaptive on a poppy?
