This page describes how to install and uninstall JRE 8 on OS X computers.
Java for Mac OS X 10.6 Update 16 delivers improved security, reliability, and compatibility by updating Java SE 6. Apple has, for some time now, been trying to distance itself from Java. That strategy involved, among other things, no longer including Java as a part of the system by default, as Apple had done in Mac OS X 10.6 (Snow Leopard) and earlier. Apple’s reasons for doing. Apple released an updated version of Java for Mac OS X 10.6 Snow Leopard, but warned that they won't be doing that again: As of the release of Java for Mac OS X 10.6 Update 3, the version of Java. 'As of the release of Java for Mac OS X 10.6 Update 3, the Java runtime ported by Apple and that ships with Mac OS X is deprecated. Developers should not rely on the Apple-supplied Java runtime being present in future versions of Mac OS X.' That's just great isn't it? With no warning at all, Java. Creating 'Native' Java Applications on Mac OS X. If you develop on Mac OS X you can use the Jar Bundler application to turn jar files into Mac OS X applications. Jar Bundler is distributed with the other developer tools and is located in Developer/Applications/.
Note:The JRE installation includes the JavaFX Runtime which is incorporated into the same directory structure.

See 'OS X Platform Install FAQ' for general information about installing JRE 8 on OS X.
Observe these requirements:
Any Intel-based computer running OS X 10.8 (Mountain Lion) or later.
Note that installing the JRE on OS X is performed on a system-wide basis, for all users, and administrator privileges are required. You cannot install Java for a single user.
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, uninstall the current version as described in 'Uninstalling the JRE'.
Installing a JRE from Oracle will not update
java -version symlinks or add
java to your path. To be able to do this, you need to install the JDK.

Determining the Installed Version of the JRE
If you have not yet installed Apple's Java OS X 2012-006 update, then you are still using a version of Apple Java 6 that includes the plug-in and the Java Preferences app. See 'Note for Users of OS X that Include Apple Java 6 Plug-in'.
