- There are various tricky issues with having multiple versions of Java (Apple's own Java 6 and Oracle JDK 7 or even 8) on one's Mac OS X system, and using different versions for different applications.
- Looking for Oracle OpenJDK builds? Oracle Customers and ISVs targeting Oracle LTS releases: Oracle JDK is Oracle's supported Java SE version for customers and for developing, testing, prototyping or demonstrating your Java applications. End users and developers looking for free JDK versions: Oracle OpenJDK offers the same features and performance as Oracle JDK under the GPL license.
- Liberica JDK provides Long term Support for all of its open source builds that act as alternatives for Java application development toolkits. The Liberica OpenJDK package with the HotSpot Virtual Machine viably replaces the Java 8 (LTS), 9, 10, 11 (LTS), 12, 13, 14, 15.
See JDK 7 and JRE 7 Installation Guide for general information about installing JDK 7 and JRE 7.
See the Mac OS X Platform Install FAQ for general information about installing JDK 7 on Mac OS X.

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.
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
Java Jdk Download Macos High Sierra
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:
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.
*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.
With macOS 10.15, Apple introduced new application security checks, which are used by Gatekeeper to verify the contents of distributed software. When you install or run software for the first time, Gatekeeper verifies that the software has been notarized. See Notarizing Your App Before Distribution.
JDK 14 is the first release that complies with the new macOS 10.15 hardening and notarization requirements. If you want to install and test earlier versions of the JDK or JRE on macOS 10.15, this document explains some expect warnings and how to proceed.
As of the time when this article was written you can still install and run non-notarized software on macOS 10.15 systems by modifying your security preferences. The following steps show you how to install a non-notarized JDK or JRE.
Note: These steps use the JDK 8u231 macOS installer as an example. These steps apply equally to all other JDK and JRE releases.
Installing the JDK Using a .dmg File
- Double-click on the
.dmg
file to begin the installation. The system verifies the.dmg
file, then opens a Finder window with the icon of an open box (package) and the name of the.pkg
file. - Double-click the package icon to start the installation app. A window appears with a status bar with text similar to the following:
- Open System Preferences, click Security & Privacy, then click the General tab. In the section Allow apps downloaded from:, the following text appears:
- A window appears with text similar to the following:
- A window appears with the following text:
Then, a window appears with text similar to the following:
'JDK 8 Update 231.pkg' can't be opened because Apple cannot check it for malicious software. This software needs to be updated. Contact the developer for more information. |
Click OK.
'JDK 8 Update 231.pkg' was blocked from use because it is not from an identified developer. |
Click the Open Anyway button.
'JDK 8 Update 231.pkg' can't be opened because Apple cannot check it for malicious software. This software needs to be updated. Contact the developer for more information. |
Click the Open button.
Installer is trying to install new software. Enter your password to allow this. |
Enter your user name and password, then click the Install Software button.
Installing the JDK from a File Archive
You don't have to modify your security preferences if you install the JDK from a .tar.gz
file archive, in particular, a prebuilt OpenJDK package. However, the system may warn you the first time you run a Java command-line tool.
Running a Java Command-Line Tool for the First Time
When you run a command-line tool for the first time (such as java
), depending on which app (such as Safari or Firefox) you used to download the installer, a window may appear with text similar to the following:
'jdk1.8.0_231.jdk' is an app created by Safari. Are you sure you want to open it? |
Click the Open button.
Depending on the folder in which you installed the JDK or JRE, another window may also appear with text similar to the following:
'java' would like to access files in your Downloads folder. |
Click the OK button.
