Please post your console log and the crash log to pastebin.com. Without context, there's not much we can do for you.

Unrecognized VM option 'PermSize128M'
This stands out to me. Normally, the FTB launcher sets -XX:permSize=256M, but I've seen some people with a global JVM flag that's trying to set it to 128M instead.

This seems to be the case for you, but it seems to be misspelled; it's missing a "=" between the PermSize and the 128M. Long story short, you need to find what is trying to set a global java argument of "-XX:permSize128M" (misspelling and all), and get rid of it. Unfortunately, I only know how to do this on Windows, not Mac OS X.

You as someone who actually owns a Mac knows more about their settings and configuration than I. The only Apple product I own is an iPad I got as a graduation gift that just sits in a drawer collecting dust.

Though my first guess would be to somehow open up the Java Control Panel.

Oh. One other place it could be. Check the "Advanced Options" in the Options in the FTB Launcher. It has an "Additional Java Parameters:" field, and it may be in there too.

I can't believe I forgot to mention there. >_>
