>OBSERVER_ on macOS High Sierra (10.13) pauses on a black windowed screen.
On some Macs running High Sierra (10.13), >OBSERVER_ will revert to black screen in windowed mode after showing the opening logo movies. Once this occurs the game will seem to pause or freeze on this screen and not progress.
This issue can be resolved by selecting the Maximize button (green) in the top left corner. This will return the window to full screen and the game will continue to the Main Menu.
