I am having issues with loading up Minecraft with mods

I am having problems with loading up Minecraft. what usually happens is I open up Minecraft(forge version 1.7.10) and I then go to open up a Minecraft world. then after several seconds of loading it then either shuts off and the launcher opens up again with a crash report or it say "shutting down internal server" and then it freezes completely. I am on MacOS btw. here is the crash report
