Mac It crashes every time I open it

[Creepers4563]

After I download the mindcrack 8.1.1 1.4.7 FTB pack. It goes to the FTB animation thingy and it just goes black screen for a moment. After that it crashes. IDK what is happening. I tried everything. I tried deleting the Mindcrack fodler and installing it again. I tried putting my ram up to 4 GB, then to 256 MB, still nothing happens. Please help me.

Put it into a new folder if you have installed FTB before and also see if that helps.
Also see your java i think mac's need 6

Looking over your log and a post by unv-annihilator, using Java 6 should fix the problem.
