https://nodecraft.com/support/games/vintage-story/how-to-upload-an-existing-vintage-story-world-to-your-server I think this link might help? I wanted to use a downloaded world/seed as it looked really fun, so I found this. I am using windows though, so I'm not sure if things are different with a mac computer. All I did was put the .vcdbs save file in the saves folder, closed and reloaded the game (Maybe keep a copy of the save in another folder just in case?) and I was able to play the game world, but some of the world generation was a little different from the original (I read somewhere apparently the same seed can generate differently? but I have no idea if that's actually true and it might just be that the world gen was different because it generated from a previous game version?) Either way, I hope this helps in some way!!
