Install OpenJDK 18 on macOSNext, you need to set JAVA_HOME and update PATH environment variables so other Java programs and tools could find the JDK. Explore the extracted directory, and you will see the Java home folder would be $HOME/OpenJDK/jdk-18.0.1.jdk/Contents/Home 2. Then extract the downloaded archive file to a directory on your computer, either using context menu provided by macOS (right click on the file, Open with > Archive Utility) or using the following command in a terminal session: tar -xf openjdk-18.0.1_macos-aarch64_ -C $HOME/OpenJDKThis unzips the archive file to the directory OpenJDK in your user home directory (be sure you created the OpenJDK folder beforehand). If both are identical, you can safely install OpenJDK 18. Then open a new terminal window, and type the following command: shasum -a 256 openjdk-18.0.1_macos-aarch64_ the checksum value printed by the shasum command with the value published by the website. Or click the macOS/圆4 tar.gz link for Intel’s CPU.It’s strongly recommend to verify SHA256 checksum of the downloaded archive file against the value published on the website (click the corresponding link sha256). ![]() Download binary distribution of OpenJDK 18 for macOSHead over to OpenJDK 18’s official download page, you will see some download links of archive files (tar.gz) as follows: Click the link tar.gz next to macOS/AArch64 if your Mac computer running on Apple’s CPU. The similar steps can be applied for any Linux operating systems. And JDK 18 is a regular update (non-LTS) of Java SE.Below, you’ll find the guide about downloading and installing OpenJDK 18 on macOS operating system. Given that you could also set version specific variables: $ export java8=`/usr/libexec/java_home -v 1.OpenJDK is a production-ready, open-source distribution of Java SE Development Kit (JDK). Library/Java/JavaVirtualMachines/jdk-13.0.2.jdk/Contents/Home You can just use part of the major version like 1.8 or 13: $ /usr/libexec/java_home -v 1.8 With argument -v you can retrieve the path of a specific version. To set it to the latest Java version use the command: export JAVA_HOME=`/usr/libexec/java_home` Setting the JAVA_HOME variable can be based on the output of the tool /usr/libexec/java_home that retrieves the installation path of your Java. The install should switch your Java version to the most recent version you just installed. Simply run the installer and the JDK version will be updated. To update the JDK, download the latest version of the JDK from the Oracle website as described above. Updates are annoying, but have to be conducted anyway. The current version is printed at the bottom. In my case, there are three versions installed. If you provide the argument -V you are presented a list of all installed Java versions: $ /usr/libexec/java_home -Vġ3.0.2, x86_64: "Java SE 13.0.2" /Library/Java/JavaVirtualMachines/jdk-13.0.2.jdk/Contents/Homeġ.8.0_131, x86_64: "Java SE 8" /Library/Java/JavaVirtualMachines/jdk1.8.0_131.jdk/Contents/Homeġ.8.0_77, x86_64: "Java SE 8" /Library/Java/JavaVirtualMachines/jdk1.8.0_77.jdk/Contents/Home Library/Java/JavaVirtualMachines/jdk1.8.0_131.jdk/Contents/Home Alternatively, you can also run the executable /usr/libexec/java_home to determine your current Java version: $ /usr/libexec/java_home In my case, I am running an old JDK version which is Java 8 Update 131 (as indicated by 1.8.0_131). Java HotSpot(TM) 64-Bit Server VM (build 25.131-b11, mixed mode) Java(TM) SE Runtime Environment (build 1.8.0_131-b11) This will give you an output like the following: $ java -version You can check the version of the Java you are running by opening a new Terminal and typing java -version. ![]() You will need administrator rights to proceed with the installation. For an instruction on how to update Java see the sections below.Īfter the download, open the DMG file and run the PKG installer file that is contained. It is recommended to install the latest version and occasionally update the installed Java version. The file is packaged in Mac's DMG installation file format. Before the download you have to accept the license agreement. Make sure to download the JDK, not the JRE (runtime environment). The official JDK should be downloaded from the official Oracle Java website. So let us see how to install and update the Java Development Kit (JDK) on macOS on your own. ![]() Since macOS 10.7 Lion (2011) it is not pre-installed anymore. In macOS 10.6 Snow Leopard and below Java was pre-installed and shipped with your Mac. If you want to write some Java code on your Mac, you will need the JDK to run your code. The Java Development Kit (JDK) is essential for Java developers and contains the Java runtime environment as well as the Java compiler and other Java libraries. This article explains how to install and update the Java Development Kit (JDK) on macOS, how to check Java version, and how to set the JAVA_HOME variable.
