For that past few months I've had problems opening my client. Simply clicking on the Minecraft block to open it does nothing, and whenever I launch Minecraft from the actual launcher in the package contents, it will open, but as soon as I go to log in it instantly crashes. I have the most recent crash report here:

Yes, I know I'm playing on a Mac, and that is a problem. Does anyone have any ideas on how to fix this error? I'm open to anything.

Thanks! - Rev

I tried both ideas on the link given... Neither of the solutions worked. How do I downgrade to Java 6?
