The Conspiracy

I know, it should be fine but the problem doesnt seem to be in that area, so im still trying to find out what it is.....

ive tried looking at this too but it all seems to be fine and im only trying to play b-team so it cant be too hard on my IMac computer, when i play normal minecraft it plays fine without lag. so i just dont know what to do at all.......

Plz help i want to play all these awsome mod packs but when i open up one my fps is 1-4 and thats only at the main menu and when i start up a new world it stays exactly the same fps 1-4 and i cant do anything about it, ive tried increasing and decreasing the GB that i allow the technic launcher im not sur if that is the permgen that others have been told to do, i also tried deleting the technic launcher completely from my computer which is infact a mac computer but yet again i download the technic launcher again and start to play but the same thing happens! i dont know how to fix my fps problems PLEASE SOME ONE HELP ME
