After Oracle releasing security updates for Java version 6 and 7, now Apple is following and distributes Java for Mac OS X 2012-005 moving to version 1.6.0_35, and thus the necessary corrections to its own OS X implementation. Moreover, the Safari plugin is configured so that it is automatically disabled when no applets are run a long time. If you want to re-enable Java, you have to do this via the plugin settings.
The update “Java for Mac OS X 2012-005” requires Mac OS X 10.7.4 or Mac OS X 10.8.1 while “Java for Mac OS X 10.6 Update 10” requires Mac OS X 10.6.8. Both updates improve the security, reliability and compatibility of Java SE 6 (by updating it to version 1.6.0_35).
Before installing the update, all web browsers and Java programs that are running must be closed.
Starting with version 7.0, Oracle will take care of the deployment of Java for Mac OS X. The latest Java 7 version for the Mac (a developer version) is available on this web page for download.
