Alright so my Friend is having some trouble with the Mindcrack Pack on start up. He has just gotten a Mac Book Pro for a present and has downloaded FTB so he could play on my server and when he tries to load up the Mindcrack pack it crashes right at the FML set up window. Here is his console log. I didnt know if it was console related or pack related so i have just went with the console logs for now.
