IMPORTANT: I changed the Program Arguments from:

--version 1.6 --tweakClass cpw.mods.fml.common.launcher.FMLTweaker

 

to:

--version 1.7.2 --tweakClass cpw.mods.fml.common.launcher.FMLTweaker

 

Because I'm using Forge 1.7.2-10.12.0.976.

 

May be it's the problem. (I think it isn't)

 

 

Thanks for helping. 

 

SOLUTION:

 

Just add:

--accessToken whatever

 

to the Program Arguments

 

Finally it should look like this:

--version 1.7.2 --tweakClass cpw.mods.fml.common.launcher.FMLTweaker --accessToken whatever

Thank you 

Thanks for this thread. This got me past the same error on OSX. I can now run with the example mode in a test world. Note, I did have to increase the default memory to 1G by adding:

 

-Xmx1G

 

to the VM arguments.

Also I Got This Also. I Am Changing Into Java 7. Look At This:
