2. Download Eclipse Java Mac Os X

This page describes how to install and uninstall JRE 8 on OS X computers.

Download Apple Java for OS X 10.7/10.8 for Mac to patch Java SE 6 components.

Download & Install Java for Mac OS X. 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. 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'. There can be multiple JDKs installed on a system, as many as you wish.

This page has these topics:

See 'JDK 8 and JRE 8 Installation Start Here' for general information about installing JDK 8 and JRE 8.

See 'OS X Platform Install FAQ' for general information about installing JRE 8 on OS X.

System Requirements

Observe these requirements:

• Any Intel-based computer running OS X 10.8 (Mountain Lion) or later.

• Administrator privileges.

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.

JRE Downloaded File

Depending on your processor, the downloaded file has one of the following names, where version is the update number:

• jre-8uversion-macosx-amd64.dmg

• jre-8uversion-macosx-x64.dmg

Installing JRE 8u40

If you are installing JRE 8u40, then follow these steps:

1. Download the file.

   Before the file can be downloaded, you must accept the license agreement.

2. From either the Downloads window of the browser, or from the file browser, double click the file .dmg to launch it.

   A Finder window appears containing an icon of an open box and the name of the .app file.

3. Double click the package icon to launch the Install app.

   A window appears that says, 'Java 8 Update 40 is trying to install a new helper tool. Type your password to allow this.'

   Enter the Administrator login name and password and then click Install Helper.

   The Install app then displays the Introduction window.

4. Click Next.

   Oracle has partnered with companies that offer various products. The installer may present you with the option to install these programs when you install Java. Specify if you want these programs installed and then click Next.

   
   

   Note: You can disable the presentation of offers during installation by specifying the --args SPONSORS=0 option in the terminal command line. For example: open /Volumes/Java 8 Update 40/Java 8 Update 40.app --args SPONSORS=0

   
   

   An Installation Progress window is displayed. Once the software is installed, a confirmation window appears and then an applet is launched to verify the version of Java installed.

5. Delete the .dmg file if you want to save disk space.

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'.

Only one JRE can be installed. Installing a JRE removes the previously installed JRE. The JRE version used by the system can be determined in one of two ways:

• From System Preferences click the Java icon from the Other category. This launches the Java Control Panel. Click About.

• Type the following in a Terminal window (note escaped space character, ignore line break):

The system will not install a JRE that has a lower version than the current version. If you want to install a lower version, first uninstall the existing version.

Uninstalling the JRE

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.

How To Update Java On Mac

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.
