New Launcher Won't Work

GibsonC78 · March 8, 2014

I have a new macbook air and have recently started playing modded minecraft, even though I've had the vanilla game for a while.

Yesterday, I downloaded the technic launcher and played on the attack of the b-team mod pack without a problem. This morning, I opened the launcher and was asked to update. So I did. This took FOREVER, but my internet has been slow recently, so that may have caused it to be slow. Anyway, after the launcher updated, whenever I open it, it just goes away then comes right back without bringing up the game screen. I have no idea how to fix this, or if I need to update my java or something. I would love some help if anybody out there knows what my problem is!

This is what's in the console window:
