Installing 64-bit java on Mac OS X Lion? When playing Minecraft 1.0, a java-based game, when I switch the rendering options to "Far", the game shows a message saying that memory usage for the game might be too high in Far rendering mode, and that I'm running 32-bit java and should install 64-bit java for the Far mode to work properly.

I can't recall ever actually installing java on this Mac at all.

Is there a way for me to install 64-bit java on my Mac?

This is an June/July 2011 iMac with Mac OS X Lion, all updates installed.
Look for Java Preferences in Utilities. There you'll find order of Java binaries browser will use.
