Java 7 For Mac

Java, a runtime environment that works 'behind the scenes' to let you use many Web sites, online services, and applications, is no longer built in with Macintosh operating systems. Apple's October 2012 software update removes the Java plugin from all Web browsers.

Following recent security vulnerabilities with Java, we recommend that Mac OS X users check their version of Java and keep it up-to-date. If Java is not installed, we recommend that you postpone installing it until absolutely necessary. If you currently have Java installed on your computer, but are not using it, we recommend disabling it. More..

Only one JRE can be installed at a time. The system will not install a JRE that has a lower version than the current version. If you wish to install a lower version of the JRE, first uninstall the current version. Installing a JRE from Oracle will not update java -version symlinks or add java to your path.

To uninstall the JRE, you must have Administrator privileges and execute the remove commands either as root or by using the sudo(8) tool.

Remove one directory and one file (a symlink), as follows:

• Navigate to /Library/Internet Plug-Ins and remove the JavaAppletPlugin.plugin directory.
• Navigate to /Library/PreferencePanes and remove JavaControlPanel.prefpane.

Do not attempt to uninstall Java by removing the Java tools from /usr/bin. This directory is part of the system software and any changes will be reset by Apple the next time you perform an update of the OS.
