How do I reinstall Java on Mac OSX Leopard? Without a DVD. I don't have any Mac disk whatsoever. I tried following the directions on http://hints.macworld.com/article.php?story=2009051215025819 but all I ended up doing was deleting a bunch of items before realizing that it was probably a waste of time and I should just go ask people myself. I have Mac OSX Leopard Version 10.5.7 The reason that I wanted to reinstall Java was because it simply was not working when I used it on Firefox or Google Chrome, but it worked on Safari until after I tried that link.
