Game Folder Gone? (OSX)

I recently got CDDA a few weeks ago, and have fallen in love with it. The depth, the nail-biting gameplay, all of it is great. I want to get into modding now, but I cannot find the Mods folder or the data folder anywhere. The only thing I could find was on the wiki about backing up saves/save scumming, but the Cataclysm folder only has 5 folders within it. Config, Graveyard, Memorial, Save, and Templates. The data folder is nowhere to be seen. Where is my data folder and where can I put my mods?

You can put mods to mods folder on same level as config folder.
