Installing Custom Stories and Mods in the Mac OS X version of Amnesia
Depending on the version of Amnesia you purchased Custom Stories and Mods will need to be installed in different places. Currently there are two primary locations to install mods, in the Application Support folder or inside the game bundle itself.
In your Application Support Folder
NOTE This currently ONLY works for the Mac App Store release of Amnesia.
This is the preferred location as it ensures a clean separation from custom content and original content for total conversion mods.
NOTE while you can install custom stories and TCs inside the game bundle with the App Store release it is highly advised not to, as any update to the game will completely erase ALL custom files installed inside of the game bundle. (Restriction imposed by Apple)
If you happen to have custom_stores installed in the game bundle, BOTH folders will be opened by the Open Custom Stories button in the launcher.
This setup has been tested with LaCaza, Through the Portal, and White Night TC with the Mac App store release of Amnesia.
Inside the game bundle
This is the old method used in all releases prior to the Mac App Store release. Custom content is stored within the application system install. To easily get to the game content.
NOTE You most likely will be asked to enter and password for an admin users to copy filed into these folders.
