The JDK supports both Intel-based (x64) and Apple Silicon (AArch64) Mac computers.
System Requirements for Installing the JDK on macOS
JDK Installation Instruction Notation for macOS
Instructions for installing JDK contains a version notation that represents the Feature, Interim, and Update version information.
For example, if you are installing JDK 18 Interim 0, Update 0, and Patch 0, then the following string represents the name of the bundle:
macOS x64 systems:
macOS aarch64 (64-bit ARM) systems:
Note:If a component has 0 as the suffix, it will be excluded.
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 18 Interim 0, Update 0, and Patch 0, then you see a string that includes the text
18. For example:
$ java -version java version "18" Java(TM) SE Runtime Environment (build 18) Java HotSpot(TM) 64-Bit Server VM (build 23.2-b04, mixed mode)
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 18 --exec javac -version

Uninstalling the JDK on macOS
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
- Remove the directory whose name matches the following format by executing the
rmcommand as a root user or by using the
For example, to uninstall 18 Interim 0 Update 0 Patch 0:

Installation FAQ for macOS
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?
3. After installing Java for macOS 2012-006, can I continue to use Apple's Java 6 alongside the macOS JDK for Java 18?
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 18`
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. 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.
