Launcher won't launch

[Pickle_with_hat]

Whenever I try to launch SkyFactory 3, or any other pack, Minecraft comes up for 3 seconds, then stops. I click launch on the twitch launcher, then it launches a java Minecraft launcher, and then I click launch on there. I am using a Mac. Thank you to who ever can help! I posted the message I get below. Can post pics if I have to.

Kind of in the wrong part of the forum, this is for launcher feedback on the FTB launcher and you're using the twitch one, but even then this is not a feedback thing or a bugg.

This is more of a Tech support case.
(so this post might be moved from a moderator on the forum)

But I'll give you a answer on your issue:
Your issue is that you use java 6 - you need to install and use java 8
