  1. Java for Mac OS X 10.6 Update 16 delivers improved security, reliability, and compatibility by updating Java SE 6.
  2. With Mac OS 10.7 (Lion) and later, the Java runtime is no longer installed automatically as part of the OS installation. Follow any of the methods below to install Java runtime.

Note:

The JRE installation includes the JavaFX Runtime which is incorporated into the same directory structure.

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:

Sun Java Mac Os X Download Windows 10

  • 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'.

Download

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.

Sun Java 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.

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...

Free Java Download For Mac

  1. Verify whether you have the current version of Java through the Java Web Site:
    http://www.java.com/en/download/installed.jsp

  3. Review the End User Agreement, then click Agree and Start Free Download. The file will save to the Downloads folder of your computer.
  4. On your computer, locate and open (double-click) the Java for Mac installer (jre-7u9-macosx-x64.dmg). A Finder window will open and display the contents of the installer.
  5. Double-click the JavaForMacOSX10.7.pkg file and follow the wizard’s prompts to install the program on your computer.
    Note: You may be asked to enter your computer’s administrator password as part of the installation process.

If you do not have administrator privileges for your computer, contact your IT administrator.
  6. A confirmation message will appear when the installation is complete. Click Close to exit the Java installer.

You should now be able to use Java-dependent web sites, applications, and resources on your computer and online. If you continue to have problems, contact the IT Help Center.
