[MAC: Modpacks won't open properly.]

This solution evaded me for the longest time. Please please please pass it on to anyone else who is having problems with a mac. It is a hell of a lot easier than trying to downgrade java manually.

Hope this helps!

Worked perfectly! Thanks Fido!

Also for anyone else I missed the [FILE NAME GOES HERE] part and didn't type in my folder name like an idiot.

I just wanted to comment and say I am having the exact same problem and I haven't been able to figure it out yet either.
