I Can't Find "edit Mods" Folder

Hi guys,
I've been trying to remove a couple mods from Crazy Craft 3 to make it stop crashing, but when I press Advanced > Edit Mods, nothing ever happens. There is supposed to be some pop-up file, but when I press Edit Mods nothing comes up. I'm using a Mac, so I can't use %appdata% to find it. Please let me know how to remove the mods, or how to find the Edit Mods folder.

Please help!
