If you still need Java 6 for Web applets after installing Apple's latest updates, there is a way to restore it and override Apple's preference for the use of Oracle's Java 7.

By clicking this arrow you will tell the system to enable the Java plug-in, but will have to quit and relaunch your Web browser in order for it to work.

Safari 6.0.4 and 5.1.9 allow you to enable the Java web plug-in on a website-by-website basis, with four settings to choose from.
