I currently have a mod-pack made using the Technic Launcher, which my friends and I use. The mod-pack works perfectly fine on windows, but when i try to launch it on Mac, the game crashes, and i know it has something to do with Immibis Core but i don't know what/why. I've tried to search the problem, and I've seen threads saying java 6 is outdated for the mod, but my Mac is using java 8, so i ruled that out. Could you please help?



Here is the crash report:
