Make fun of me but I need Java to play Runescape (make fun) and it says Apple uses its own java..but I cant find it? If I already have it, its out of date. I already searched fpr software update.
Lion users can install the current version of Java 7 by going to http://www.java.com/, but that may not solve your problem.
If you previously had Java 6 from Apple installed, then Apple has disabled it for use in Safari and has not announced any plans to update it for Lion / Mountain Lion users. You might be able to use it at your own risk, even though it's unsafe, with Firefox by following the instructions here.
If you installed Java 7 and need to switch back to Java 6 in any browser you will need to follow these instrucitions http://support.apple.com/kb/HT5559.
