This page is for anyone who needs help or is new to having Frets on Fire on their Mac. First of all, if you want to run regular stock Frets on Fire, your best bet would be to download version 1.2.438 here http://frets-on-fire.en.softonic.com/mac
Once you download that you can use only graphical mods unless it says that the mod is for Mac. This is because the source code for Windows, Linux, and Mac are all different. If you want to upgrade to the fixed 1.2.451 download it here link
Trinidude4 has ported many standalone mods for mac such as MFH Mod 3.0, RF-mod 4, Ultimate Coffee Mod 2, Hering Mod. 1.99a. Many files created by trinidude4 for Mac, including the latest FoFiX patches and fixed versions of different versions of FoF are located here.
