When starting a Java application through the command line, the system uses the default JDK. There can be multiple JDKs installed on the macOS system. You can determine which version of the JDK is the default by entering java -version in a Terminal window.
This topic includes the following sections:
- Similar to what @klanomath suggests: Copy the pkg off the disk image so it can be edited. Extract pkg contents in Terminal (assumes 'JDK 7 Update 67.pkg' is your pkg name): pkgutil -expand JDK 7 Update 67.pkg JDK 7 Update 67.unpkg Edit the Distribution file with your favorite text editor.
- Java 11 The implementations of Java 8, 9, 10, and 11 based on OpenJDK from vendors such as Azul Systems, Oracle, and AdoptOpenJDK run on macOS High Sierra and Mojave (and some older macOS as well). Java 12, not yet released for production, runs on High Sierra as well.
- Java for OS X 2015-001 is what you need. Of course, the download page still refers only to 10.7-10.11.
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.

You can determine which version of the JDK is the default by entering java -version
in a Terminal window. If the installed version is 12 Interim 0, Update 0, and Patch 0, then you see a string that includes the text 12
. 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 12 --exec javac -version
Installing the JDK on macOS
- Download the JDK
.dmg
file,jdk-12.
interim.update.patch-macosx-x64.dmg
.Before the file can be downloaded, you must accept the license agreement.
- 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. - Double-click the
JDK 12.pkg
icon to start the installation application.The installation application displays the Introduction window. - Click Continue.
- Click Install. A window appears that displays the message: Installer is trying to install new software. Enter your password to allow this.
- Enter the Administrator user name and password and click Install Software.The software is installed and a confirmation window is displayed.

file if you want to save disk space. Uninstalling the JDK on macOS
You must have Administrator privileges.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.
- Go to
/Library/Java/JavaVirtualMachines
. - Remove the directory whose name matches the following format by executing the
rm
command as a root user or by using thesudo
tool:/Library/Java/JavaVirtualMachines/jdk-interim.update.patch.jdk
For example, to uninstall 12 Interim 0 Update 0 Patch 0:
$ rm -rf jdk-12.jdk

Installation FAQ on macOS Platform
This topic provides answers for the following frequently asked questions about installing JDK on macOS computers.
1. How do I find out which version of Java is the system default?
When you run a Java application from the command line, it uses the default JDK. If you do not develop Java applications, then you do not need to worry about this. See Determining the Default JDK Version on macOS.
2. How do I uninstall Java?
See Uninstalling the JDK on macOS.
3. After installing Java for macOS 2012-006, can I continue to use Apple's Java 6 alongside the macOS JDK for Java 12?
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 12`
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.
4. Can I restore Apple Java after uninstalling Oracle Java?
Go back to Apple Java using the following instructions:
Uninstall Oracle Java by deleting the plug-in file. From a command-line, enter:
$ sudo rm -rf '/Library/Internet Plug-Ins/JavaAppletPlugin.plugin'
Create a symlink using the following command, entered on a single line:
$ sudo ln -s /System/Library/Java/Support/CoreDeploy.bundle/Contents/JavaAppletPlugin.plugin '/Library/Internet Plug-Ins/JavaAppletPlugin.plugin'
5. What happened to the Java Preferences app in Application Utilities?
The Java Preferences app was part of the Apple Java installation and is not used by Oracle Java. Therefore, macOS releases from Apple that do not include Apple Java will not include Java Preferences.
Java 11 The implementations of Java 8, 9, 10, and 11 based on from vendors such as, and run on macOS High Sierra and Mojave (and some older macOS as well). Java 12, not yet released for production, runs on High Sierra as well. LTS Note that Java development has changed recently.

Java for macOS 2017-001 installs the legacy Java 6 runtime for macOS 10.13 High Sierra, macOS 10.12 Sierra, macOS 10.11 El Capitan, macOS 10.10 Yosemite, macOS 10.9 Mavericks, macOS 10.8 Mountain Lion, and macOS 10.7 Lion.
Oracle and the Java community have adopted a faster cadences for releases, a fashion known as the. Every six months a new version arrives, as discussed in. These are production-ready fully-tested releases. However, these versions may not be supported free-of-cost with patches after the successive version arrives. Cox panoramic my passport for mac free. The exception is that every three years, the sixth release in succession shall be designated a version. Versions 8 and 11 are both LTS, as will be version 17.
This means the version will receive updates and fixes for years instead of months. This applies, at least, customers paying a commercial vendor. Free-of-cost implementations may also receive updates under LTS from some providers.
We’ve yet to see if that happens or not. This approach using rapid delivery train with LTS is new in the Java world.
