I am a mac user and since the new OS X update my minecraft won't launch. When I open it it gives me a blank page in the 'game output'. When I switch to the 'launcher log' tab this is the error I get:

I read on several forums that I need to reinstall java/ minecraft. Or get to java 7 version. I've tried everything I could find. When I look at the code I'm guessing I need to give minecraft permission to use java, can I do that?

have you had anyluck? i am having a similar problem, but we have only just bought the download, set up account, logged in, push play, and launcher is blank?????

I tried sending Mojang and email but they haven't replied yet, been 3 weeks now.

I think I fixed it. When you open your Minecraft go to edit profile, go down to Java Settings(advanced) and uncheck the two boxes. Worked for me.
