So, several months ago I was able to install up to 30-50 mods no problem. Now, I just wanted to get back into the whole modded survival thing again, and I only want to use 16 mods. Here is where things get weird, I'm able to start up the world but 3 seconds in it starts to "shut down internal server". Then the crash report comes. Before you look at it I am using a mac if that helps in any way. Here it is:
