System Requirements for Installing the JDK on macOS

The following are the system requirements for installing the JDK on macOS:

• Any Intel-based computer running macOS.

• Administrator privileges.

  You cannot install Java for a single user. Installing the JDK on macOS is performed on a systemwide basis for all users. Administrator privileges are required to install the JDK on macOS.

Determining the Default JDK Version on macOS

When starting a Java application through the command line, the system uses the default JDK.

You can determine which version of the JDK is the default by entering java -version in a Terminal window. If the installed version is 13 Interim 0, Update 0, and Patch 0, then you see a string that includes the text 13. For example:

To run a different version of Java, either specify the full path, or use the java_home tool. For example:

$ /usr/libexec/java_home -v 13 --exec javac -version

Installing the JDK on macOS

1. Download the JDK .dmg file, jdk-13.interim.update.patch_osx-x64_bin.dmg.

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

2. From either the browser Downloads window or from the file browser, double-click the .dmg file to start it.
   A Finder window appears that contains an icon of an open box and the name of the .pkg file.
3. Double-click the JDK 13.pkg icon to start the installation application.
   The installation application displays the Introduction window.
4. Click Continue.
5. Click Install.
   A window appears that displays the message: Installer is trying to install new software. Enter your password to allow this.
6. Enter the Administrator user name and password and click Install Software.
   The software is installed and a confirmation window is displayed.

Uninstalling the JDK on macOS

Note:

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 that you perform an update of the OS.

1. Go to /Library/Java/JavaVirtualMachines.
2. Remove the directory whose name matches the following format by executing the rm command as a root user or by using the sudo tool:
   /Library/Java/JavaVirtualMachines/jdk-13.interim.update.patch.jdk

   For example, to uninstall 13 Interim 0 Update 0 Patch 0:

   $ rm -rf jdk-13.jdk

3. After installing Java for macOS 2012-006, can I continue to use Apple's Java 6 alongside the macOS JDK for Java 13?

If you want to continue to develop with Java 6 using command-line, then you can modify the startup script for your favorite command environment. For bash, use this:

$ export JAVA_HOME=`/usr/libexec/java_home -v 13`

Some applications use /usr/bin/java to call Java. After installing Java for macOS 2012-006, /usr/bin/java will find the newest JDK installed, and will use that for all of the Java-related command-line tools in /usr/bin. You may need to modify those applications to find Java 6, or contact the developer for a newer version of the application.
