Yes, the DLCs do work on Mac! Sorry for the lateness of this reply. If you need help adding them to the base game, let me know, and thank you so much for playing!

Sure, I can help! You want to start by downloading the Mac version of the main game and making sure it's somewhere you can find. Then, when you download the Wedding DLC, it should come with a file called "dlc_wedding.rpa". You want to move that file into the "game" folder of the main game's directory of folders. If you need more help, just let me know, and thank you so much for playing!
