I have made the old Mac version from August available to download again. Maybe you could try this with new MacOS to see if this works?

Thanks for the feedback! I am not a 100% sure yet, what's happening, but it's getting clearer.
You can download the mods now separately here and copy them into the data folder. If this works and you can use them, everything is clear. If not, you can at least play it without mods :D
They are not very useful in the current state anyway.
