ok i don't know anything about java or anything really but when i run the launcher i can't even get regular minecraft to run through it. the only pack that shows FML is tekkit lite and voltz. both of which the FML runs fine just as it does in my MultiMC. but the screen stays white fro all of the packs even vanilla. and just quits, no crash report, no mac telling me it's quit unexpectedly. it just quits. i don't know what i'm doing wrong i did the process laid out by cheap shot. nothing. but it takes nothing for me to do anything on multimc i don't need a Lwjgl fix (whatever that is) in fact i run a heavily modded, 80 some mods, through MultiMC no problem. Even trouble shot my way through some stuff when it didn't work. but sadly i just can't seem to get your launcher to work. though i'd very much love to. Now i'd like to have some help and all i can tell you is i've got the latest java and mac os. and i am using build 195 of the mac launcher. anything else i can't help with as the launcher itself isn't making any logs like it's not crashing at all. So if anyone can help i'd be very appreciative and if i didn't give enough detail just ask me for more i will try to provide more information but i think i covered just about everything.
