It looks like Apple is officially turning Java support over to Oracle in October. Oracle released a Java 7 update this week. Is Minecraft going to work with Java 7 on the Mac at some point?

ahh My Minecraft Can't Run on Java 7 and worset thing is i can't downgrade

My mine craft will not work on java seven either, i cant downgrade either, and if you figure out how it works then how?

Minecraft doesn’t work on Java 7 for Mac’s. If you need to uninstall Java 7 go to this link: http://www.java.com/en/download/help/mac_uninstall_java.xml
Sko's post will tell you what version of java you should have: http://www.minecraftforum.net/topic/649868-guide-mac-support-101/#java

Minecraft does not work for me if I use java 7 on my mac. This is the crash I get... copied directly from the crash report because I don't know how to upload the file.

So I figured out a way to downgrade!

All you need to do is paste the following commands into terminal

1. Open terminal by searching it in spot light
2. Paste this command in to remove java 7

sudo rm -fr /Library/Internet\ Plug-Ins/JavaAppletPlugin.plugin

3. And then paste this command to instale java 6

sudo ln -s /System/Library/Java/Support/CoreDeploy.bundle/Contents/JavaAppletPlugin.plugin /Library/Internet\ Plug-Ins/JavaAppletPlugin.plugin

Worked for me!
