I don't have the Campaign edition installed now, so I can't check it. But my first post says the Mods folder is in ~/Library/Containers/com.aspyr.civ5campaign/Data/Library/Application Support/Civilization V Campaign Edition/MODS Have you looked there? ~/Library/ is a hidden folder in your Home folder. Use the Go/Go to folder ... menu item in the Finder and copy/paste the above path into it. [UPDATE] I found I do have the campaign edition installed, and it does all still work as I described in the first post.
