Mr.Nezbit

So I downloaded the 16th Century Northern Hemisphere mod for Warband and I cannot run it on my Macbook Pro. That may be the problem but for larger mods such as Prophesy of Pendor and Perisno run beautifully. With this mod I used TheUnarchiver to extract the .7z file and while loading the mod into the steam folder I noticed that the files within the mod folder such as Actions,factions, and map were all .txt files these are just a few examples, there is also no resource folder. I am extremely confused and would appreciate any help that can be lent.
