Hey guys, here is my crash report. I know i have quite a bit of mods running, but my computer should be able to handle them.

my computer is a MacBook Pro mid-2010 4GB ram. Its the ply app i have open and allowing 2G of ram for java in the java settings in my launcher. Still if I pull up activity motor, sometimes it will say my CPU for mine craft is up to 190%, yet the memory says it is only using ~800mb or so. When i press f3 my FPS is usually around 20, never better, sometimes worse (around 10-15) don't know why, even without mods loading the speed is the same. I have graphics to fast, particles to min, but i believe i should be able to have all those things with my computer. Also running mavericks which i hear can take up to 2gb of ram, but that still allows 2gb for mine craft itself. Please help, would love to get my FPS to a solid 25-30 with nice graphics and particles with no crashing. It doesn't crash right when it opens, i can sometime play for 5min, other times 1 minute.
