Mac OS X Port Project. The goal of this Project is to produce a high-quality, open source version of JDK 7 for the Mac. The final release has the following goals: Pass all appropriate certification tests for Java SE 7; Include a complete, native Cocoa-based UI Toolkit; Provide excellent performance; This Project is sponsored by the Porters. How are Java updates managed on macOS? Every time you start a Java applet or a Java Web Start (JWS) application, the system starts your program and determines in the background (so that performance of your Java application is not affected) if it has checked for a Java update in the last 7 days. In this article, I will demonstrate how to install Java OpenJDK 15 on macOS Catalina in 2020. Download and Install OpenJDK 15 Download the.tar.gz version of OpenJDK 15 from jdk.java.net/15/ and move the file to /Library/Java/JavaVirtualMachines/ on your mac. Then, extract it and delete the archive. Newest OpenJDK (e.g. 15) is recommended for Dark Mode support. The zip file contains Mac application bundle: just save it and double-click to extract. On first run right-click and select Open or go to Settings/Security and allow installing apps from other sources besides Mac Store.
JDK 9 & Later
REDWOOD SHORES and CUPERTINO, California—November 12, 2010—Oracle and Apple® today announced the OpenJDK project for Mac OS® X. Apple will contribute most of the key components, tools and technology required for a Java SE 7 implementation on Mac OS X, including a 32-bit and 64-bit HotSpot-based Java virtual machine, class libraries, a networking stack and the foundation for a new graphical client.
Oracle's OpenJDK JDK binaries for Windows, macOS, and Linux areavailable on release-specific pages of jdk.java.net as .tar.gz or.zip archives.
As an example, the archives for JDK 13 may be found on jdk.java.net/13 and may be extractedon the command line using
$ tar xvfopenjdk-13*_bin.tar.gz
or
$ unzipopenjdk-13*_bin.zip
depending on the archive type.

This is a short note about getting started with Java 11 LTS or Java 13 on macOS Catalina. As you probably know, starting with Java 11 there was a big change in the license under which the official Oracle JDK is provided. In short, you need to buy a license from Oracle if you want to use the official JDK in a commercial setting. As far as I know, using Oracle’s JDK on your private computer for testing and learning purposes is allowed.
That being said, for most users OpenJDK is the new JDK of choice, it is provided under an open source license and you don’t need to pay for using it.
There is also a video version of this tutorial:
At this time, Java 11, the long term release or LTS, of Java is no longer supported on the OpenJDK website. You can still get the archived version, but this is not recommended because it doesn’t include any new security patches. If you still need to use Java 11, use an alternative build like the one from AdoptOpenJDK. From the AdoptOpenJDK page you will download a pkg file that you can install on your macOS machine directly by double clicking on it.
After you’ve installed the AdoptOpenJDKpkg file, check if you can use it with:
This is what I see on my machine:
If you prefer to use the Java version provided by the OpenJDK website, you will need to use Java 13. Start by getting OpenJDK, chose the macOS version. Extract the archive by double clicking on the file or, assuming it is in your Downloads folder, write this in your Terminal:
Next step, is to move the extracted folder to a place where macOS searches for Java JDK:
Now, check if you’ve successfully installed the JDK with:
This is what I see on my machine:
Just to be sure that everything works, try to compile and run a simple program:
Save the above as HelloWorld.java and compile it with:
If you want to run the compiled version:
This is what I see on my machine:
Side note, you can also run directly the program, without the separate compilation step with:
Openjdk For Macos
but this is usually slower than compiling the code with javac and running the compiled code.
