Hi, My friend is having trouble connecting to my server. He has all the mods installed on his mac, yet a few mods jsut arent working. We has the exact same mod downloads as me but still cant join. When he tries to enter the server it tells him he am missing Harvestcraft, Backpacks, BetterBuildersWands, and Hammertime, even though they are in the folder with all the other mods that do work. Plz help ;D
