Java update crashes OSX
I have a mid-2010 MBP with i7 and 8GB RAM, SSD, OSX 10.7.5. I've been trying to get Minecraft working on it for my kids, but when launching Minecraft a message throws up that I need a Java Runtime Environment. When I do that, the JRE downloads, starts to install, but then hangs at "optimizing system for performance" about 80% through. Not even a command-option-escape will respond. I have to do a hard reset by pressing and holding down the power button to reboot.
From the command line I do a java -version, and it says not runtime is installed and again prompts me to install it (if i follow through the system hangs every time). From the java console in Utilities, it says i have java 7 update 10. Not sure if it matters, but i have both firefox and chrome installed as well (in case there is some plugin that is corrupt).
How can I completely uninstall java so I can do a fresh install? I followed some tips on the web to drag the java applet to the trash, but that didn't seem to work. I'm thinking I need to reinstall OSX. Irritating...for a simple Minecraft game!!
