Mac Gaming Mods

So recently i converted one of my favorite halo maps of all time, Headlong, and it worked really good, but when i shot either the battle rifle or the plasma pistol charge it crashed. I don't know how to even start cause its protected. Any suggestions would be nice, i used pearl 2 and converted Headlong PB2, which is a CE map and converted it to MD. Any suggestions are welcomed.

Anyone, I could use some help please or at least suggestions.

What type of computer are you using/OS? Upload the map and I will take a look.

Thanks, Im using on a Macbook Pro Running OS X 10.7.5. Here the map link, http://www.mediafire.com/download/tr7u8 ... _1.map.zip

So how is it coming along i would like to know whats happening?
