    posted a message on Can't Launch Any Minecraft Modpacks

    So I'm using a Mac and everything should be updated, however, I can't launch a single pack.  I have the latest minecraft installed and am new to the curse launcher.  I need some help figuring out what exactly is going wrong and how to fix it.  After I installed the FTB Crackpack I clicked play and got what appeared to be the vanilla launcher and I pressed play again.

    This is what I get in my Game Output:

    I think it may be an issue with my java based off what I've read online but then again I really have no clue.
