Problem with mods

[Mudbill]

The problem is that Mac doesn't use .bat files. They are only for Windows users. It is possible to use .sh or .command files as an alternative, but most people probably don't include them in their mods.

Nevertheless, you can make your own, but it depends whether you use Steam or not. If you do, you must set the launch option to the White Night config file, but if not, (I think) you need to launch the game app itself with the White Night config as a flag.
Which version are you on?
