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

I found the menu is only enabled when your screen resolution is able to support pixel accurate display( so as physical size). This is annoying because making a screenshot always generates a picture at the current size of the simulator on Xcode 9.1. It requires to the simulator to display in the pixel-accurate mode for qualified screenshots. For iPad Pro(12.9-in, 2732 x 2048 pixels), the mode is only available in landscape when my MacBook Pro is set to "More Space"- with actual resolution at 3840x2400.
