We already talked about the method, via which you can create a screenshot on Mac.

And that’s how you screenshot on Mac but only the Window.
When the cursor transforms into a crosshair, hit ‘Space.’ And then click on a Window (that’ll appear blue under the crosshair to indicate that it has been selected).
For taking screens shot of a single window on your desktop, we have to more or less follow this guide.
