The Steps 1-3 DLCs also work on Mac. The file you get when you access the download here on itch.io works on all of the different operating systems. If you need any help getting it set up, just let me know!

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!
