macOS - `locateOnScreen()` coordinates are off by a factor of 2

See original GitHub issue

locateOnScreen() works perfectly on Ubuntu Linux but on MacOS it always adds a varying offset. As X increases, the coordinates returned by locateOnScreen() increases by a certain ratio, similar for Y but increases slightly less.

Doesn’t matter how many desktop/workspaces I have active, the result is the same.

The factor 2 is devicePixelRatio.
pixelRatio = pyautogui.screenshot().size[0]/pyautogui.size().width
