Qmake creates an “empty.lproj” file every time we make an app bundle (I
like to go the app bundle route when making MKXP-1S), but we don’t use
those, so why worry about their changes?
The .app happens to be a tweaked version of the one provided when
grabbing a copy of the game from Steam, as I am unfamiliar with the
process of collecting frameworks into an app bundle, at least with
cmake/qmake. All you need to do is replace the .app in
~/Library/Application Support/Steam/SteamApps/OneShot/ to play on Mac!
