Launcher crashes, even with vanilla

[Filsk]

When I try to use any modpack, or even vanilla, the launcher is stuck on a white screen before the mojang logo appears. Any solution? I'm on OS X Lion

Thanks

P.S: Sorry if this was already solved in other threads, but I didn't find any.

EDIT: Solved now. Followed the instruction on this link:

It works, took some time to load everything, but works
