The following comes from the BUG Mod "Read Me" file, with slight changes to make it specfic for the Mac. You still need to make the patch in post 172. (The dots are only there to indent the folders to show what is inside what, because I could not figure out how else to make the indents.):
In both cases, you need to create the BUG Mod folder. It does not already exist. I have mine installed in CustomAssets, where it works fine. I cannot vouch for the method using Applications folder.
2. INSTALLATION
WARNING: You should never modify or replace the original BTS Assets files.

AS A MOD
To install BUG as a mod so that you must load it to play, place the folder that contains this README file into your BTS's Mods folder.
~/Applications
...../Civilization IV
......./Beyond the Sword
........./Mods
.........../BUG Mod
__________________________________________________
CUSTOM ASSETS
To install BUG so that it is always active with your games (this will allow you to use it with succession games and games you open from the CivFanatics forum), you must first copy the files and folders from the Assets folder in the unzipped BUG Mod download into your CustomAssets folder. Next create a "BUG Mod" folder next to CustomAssets and copy the Info and UserSettings folders into it. Finally, copy the files inside PrivateMaps into BTS's PublicMaps folder.
At each step it is important that you tell it to overwrite files.
~/Documents
...../Beyond the Sword
......./CustomAssets <-- folders in Assets go here
......./BUG Mod <-- create this folder
.........../Info <-- copy these two folders here
........../UserSettings <-- copy these two folders here
......./PublicMaps <-- copy files from PrivateMaps here
In both cases, you need to create the BUG Mod folder. It does not already exist. I have mine installed in CustomAssets, where it works fine. I cannot vouch for the method using Applications folder.
