On macOS Catalina, the application needs to ask for permissions to
access some folders, such as the Desktop, Downloads, and Documents
folder. It for example asks for permission when listing files in
one of those folders or trying to read a file that was created by
another application and not selected using the system Open panel.
Since the default savegame path on macOS is in the Documents
folder it will ask for permissions to access this folder when we
open the Load Game dialog or try to load a savegame that was
copied there manually). So, while not required, it seems a good
idea to provide an explanation why ScummVM wants access to the
Documents folder.
macOS 10.14 introduced a dark theme in addition to the nornal
aqua theme. Applications compiled with the 10.14 SDK or above
are automatically opt in for both, but applications compiled
with an older SDK are not and still use the aqua theme even
when the system is set to use the dark theme. Those applications
need to explicitely opt in to use the dark theme.
This fixes bug #11305: Dark Mode is not supported
