We will show you two ways to install Java JDK on Mac, via the popular Homebrew package manager and manually installation.
1. Homebrew
1.1 Install Homebrew and update it.
1.2 Add adoptopenjdk/openjdk.
1.3 Find all available JDK.
The output may vary.
1.4 Java 8, 9, 10, 11, 12, 13, choose one to install.
Java Runtime For Mac
This example will install Java 8 and 11 for testing.
1.5 Where Java is installed?
/usr/libexec/java_home -V
Homebrew will install the JDK at folder
/Library/Java/JavaVirtualMachines/
, and this folder is Mac’s standard folder for Java installs.1.6 Test it, by default, Mac takes the highest version.
1.7 How to do version switching? Refer to below 3. version switching
2. Manual installation
The example shows you how to download the early access JDK 14 and install it on Mac OSX.
Steps
- Download JDK.
- Puts the JDK folder at
/Library/Java/JavaVirtualMachines
. - Export
JAVA_HOME
.
2.1 Download the early access JDK 14 from the OpenJDK website.
2.2 Extracts tar file to
/Library/Java/JavaVirtualMachines
2.3 Export
JAVA_HOME
.Find out where is JDK 14.
Create or edit the existing
~/.bash_profile
with a text editor.Export
JAVA_HOME
, save and exit.~/.bash_profile
Reflect the changes
2.4 Test it.
3. Version Switching
In this tutorial, we installed the Java 8 and Java 11 via
Homebrew
(Step 1), and Java 14 manually (Step 2), so this Mac has three versions now. And the Mac is using the JDK 14.Note
There are tools like jEnv to manage the Java version switching, but I prefer to manage with

export JAVA_HOME
manually, it’s simple and easy to understand, no black box magic.3.1 Create or edit the existing
~/.bash_profile
with a text editor like vim or nano, export JAVA_HOME
to the specified JDK we want to use on Mac.The above changes will make
JAVA_HOME
point to JAVA 8.3.2 Reflect the changes.
Done.
If we want to switch JDK version again, update the
~/.bash_profile
and export JAVA_HOME
to other JDK version.References

System Requirements
- Any Intel-based Mac running Mac OS X 10.7.3 (Lion) or later.
- Administrator privileges.
Note that installing the JDK on a Mac is performed on a system wide basis, for all users, and administrator privileges are required. You cannot install Java for a single user.
Installing the JDK also installs the JRE. The one exception is that the system will not replace the current JRE with a lower version. To install a lower version of the JRE, first uninstall the current version.
JDK 7 Installation Instructions
Installation of the 64-bit JDK on Mac Platforms
When you download the Java Development Kit (JDK), the associated Java Runtime Environment (JRE) is installed at the same time. The JavaFX SDK and Runtime are also installed and integrated into the standard JDK directory structure.
Depending on your processor, the downloaded file has one of the following names:
- jdk-7u<version>-macosx-amd64.dmg
- jdk-7u<version>-macosx-x64.dmg
Where <version> is 6 or later.
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 .dmg file to launch it.
3. A Finder window appears containing an icon of an open box and the name of the .pkg file Double click the package icon to launch the Install app.
4. The Install app displays the Introduction window. Click Continue.
4a. Note that, in some cases, a Destination Select window appears. This is a bug, as there is only one option available. If you see this window, select Install for all users of this computer to enable the continue button. Click Continue.
5. The Installation Type window appears. Click Install.
Java Runtime Environment 1.5.0 Download
6. A window appears which says 'Installer is trying to install new software. Type your password to allow this.' Enter the Administrator login and password and click Install Software.
7. The software is installed and a confirmation window appears. Click the ReadMe for more information about the installation.
After the software is installed, delete the dmg file if you want to save disk space.
Determining the Default Version of the JDK
A: If you have not yet installed Apple's Java Mac 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 Macs that Include Apple Java 6 Plug-in.
There can be multiple JDKs installed on a system – as many as you wish.
When launching a Java application through the command line, the system uses the default JDK. It is possible for the version of the JRE to be different than the version of the JDK.

You can determine which version of the JDK is the default by typing java -version in a Terminal window. If the installed version is 7u6, you will see a string that includes the text 1.7.0_06. For example:
To run a different version of Java, either specify the full path, or use the java_home tool:
For more information, see the java_home(1) man page.
Uninstalling the JDK
Download Jdk For Mac
To uninstall the JDK, you must have Administrator privileges and execute the remove command either as root or by using the sudo(8) tool.
Navigate to /Library/Java/JavaVirtualMachines and remove the directory whose name matches the following format:*
For example, to uninstall 7u6:
Java Runtime Download For 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 Runtime Environment Windows 10
*The 7u4 and 7u5 releases were installed into a directory that does not follow this format. To uninstall 7u4 or 7u5, remove the 1.7.0.jdk directory from the same location.
