So you can either disable this Safari feature but going into Settings -> General and unselect the “Open “safe” files after downloading” or just copy the download link (right click on the tar.gz link and click “Copy Link”) and then use curl at the command line (my preference!): Most folks will just click the link and this works however by default Safari will uncompress the file after download which will make it difficult to verify the sha256 hash. Since I’m on an Apple M1, I’ll go ahead and download the macOS/AArch64 file. You can also check out the Apple Support article “Mac computers with Apple silicon” for additional details. To determine this, choose the Apple menu -> About this Mac and then look at the Chip section: Since Apple moved using their own ARM chips (“Apple Silicon”) starting with the M1 series, you’ll have to choose between “macOS / AArch64” (Apple M1 and above) and “macOS / 圆4” (older Intel chips). For the demo, we’ll just go with the latest version (OpenJDK 19 as of Nov 2022) and you’ll be taken to a page with links to platform specific downloads. So don’t click the green Download Java button! :-) Instead, click on the OpenJDK Early Access Builds which will then let you select which JDK you want to install.

OpenJDK Runtime Environment 18.9 (build 11+28) bash_profile) and then running each alias, now I’ve got OpenJDK 11 set up and ready to go! $ j11

bash_profile, I now have: alias j11='export JAVA_HOME=/usr/libexec/java_home -v 11 java -version'Īlias j10='export JAVA_HOME=/usr/libexec/java_home -v 10 java -version'Īlias j8='export JAVA_HOME=/usr/libexec/java_home -v 1.8 java -version' Updating my aliases to quickly switch versions in my.

Once you’ve moved it there, java_home -V now shows the new JDK in place: $ /usr/libexec/java_home -Vġ1, x86_64: 'OpenJDK 11' /Library/Java/JavaVirtualMachines/jdk-11.jdk/Contents/Home gz file to the same location would make sense. Knowing that your available JDKs are installed to /Library/Java/JavaVirtualMachines/ by default, moving the contents of the downloaded OpenJDK 11 dir from inside the. Library/Java/JavaVirtualMachines/jdk1.8.0_151.jdk/Contents/Home To switch between JDKs, use /usr/libexec/java_home -v version (e.g. usr/libexec/java_home -V: This lists all installed JDKs, which is shown below: $ /usr/libexec/java_home -Vġ0, x86_64: 'Java SE 10' /Library/Java/JavaVirtualMachines/jdk-10.jdk/Contents/Homeġ.8.0_151, x86_64: 'Java SE 8' /Library/Java/JavaVirtualMachines/jdk1.8.0_151.jdk/Contents/Home usr/libexec/java_home: This will show you where the current JDK home is, for example: /Library/Java/JavaVirtualMachines/jdk-10.jdk/Contents/Home

If you’ve done any fiddling with different JDK versions on MacOS before, you’ve probably come across the ‘/usr/libexec/java_home’ utility, which composes a number of useful things relating to the JDK that you’re currently using in your PATH. Click here for my previous article about this utility and answers to this StackOverflow post, which includes one of the most extensive and useful guides to running different JDK versions on MacOS that I’ve seen.

tar.gz for OpenJDK 11 directly from, there’s no obvious installation instructions (at least that I could find) on the OpenJDK website or in the.
