Mac All 1.6.4 Packs Crash upon Launch

[Baby_Cabbage]

All of my 1.6.4 packs launch and open up console but they do not display the mojang loading screen. Within 5-10 seconds the console closes. I am running Mavericks on my Mac. I have Java 7 installed. The crash report is here:

Thank you for any and all help!

My situation is very similar to yours - I run a small mac machine, and have played FTB Mindcrack some time ago. Since a day or two ago, I tried to run the game again, but have been hitting some road bumps. Whenever I try to run the mindcrack mod pack, the game crashes just moments after launch. Im sorry I don't have a fix to share yet, but Im working on it. GL.
