Ok, I'm not very smart at computers, so it'd be best if you could give me as basic an explanation as you can so as to not confuse me, if you know how to fix this.
I'm running on a Mac, and i've got 1.4.5, and I've installed FML and gotten so far as logging in and seeing the "setting up your Minecraft environment" thingy, but a box pops up and says it had a fatal error and to consult a file in my Minecraft for help, but it just confuses me. Is there a way to fix this?
I have the exact same problem, heres the crash log:
