Install Mods (Non-Steam, Mac)

How do you install mods, for democracy 3 on mac. I tried doing it, but it never works, it should the mod as installed, but I can never play with the mod features or the country.

Thankyou, to anyone who helps.

After YEARS of using Demo 2 and 3 … I just NOW figured this out. I attached the screens shots of the paths for the mod I just got working.

Ok, So I installed the Poland Mod from the official site, as per your screenshots.

I can see on the start screen that the Mod is installed no problem, however I can’t play the Mod.

Have I done something wrong?
