How can I get full-resolution screenshots when the Simulator's “Pixel Accurate” option is disabled?

Question

On Xcode 9.1 the Pixel Accurate option is disabled and grayed out under the Window menu.

How can I take App Store screenshots without this

Answer 1

As of Xcode 12 we always enable all of the options.

In previous releases they were not enabled unless your screen was large enough to display the device at the full resolution without running off the edges.
