Installing OpenJDK 17 on macOS: A Step-by-Step Guide

Prerequisites

Before we begin, make sure you have the following:

• macOS High Sierra or later (10.13 or later)
• A Mac with a compatible processor (Intel Core i5 or later)
• A compatible graphics card (Intel HD Graphics 4000 or later)
• A valid Apple ID and a valid credit card (for the macOS App Store purchase)

Step 1: Download and Install the OpenJDK 17 Installer

To install OpenJDK 17 on your macOS, you’ll need to download the installer from the Oracle website. Here’s how:

• Go to the Oracle website (https://www.oracle.com/java/technologies/javase-downloads.html)
• Click on the "Download" button for macOS
• Select the "OpenJDK 17" installer for macOS
• Choose the correct architecture (32-bit or 64-bit) and processor type (Intel Core i5 or later)
• Click on the "Download" button to start the download process
• Once the download is complete, open the downloaded file and follow the installation instructions

Step 2: Install the Java Development Kit (JDK)

After installing the OpenJDK 17 installer, you’ll need to install the Java Development Kit (JDK) to use OpenJDK 17. Here’s how:

• Open the Terminal app on your Mac
• Type the following command to install the JDK:

  ./jdk-17.0.2.jdk

• Follow the prompts to accept the license agreement and download the JDK
• Once the download is complete, install the JDK by running the following command:

  ./jdk-17.0.2.jdk -i

• This will install the JDK and its dependencies

Step 3: Install the OpenJDK 17 Runtime

To use OpenJDK 17, you’ll need to install the runtime environment. Here’s how:

• Open the Terminal app on your Mac
• Type the following command to install the OpenJDK 17 runtime:

  ./jdk-17.0.2.jdk -i

• This will install the OpenJDK 17 runtime and its dependencies

Step 4: Configure the System Properties

To ensure that OpenJDK 17 is installed correctly, you’ll need to configure the system properties. Here’s how:

• Open the Terminal app on your Mac
• Type the following command to set the JAVA_HOME environment variable:

  export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk-17.0.2.jdk/Contents/Home

• This will set the JAVA_HOME environment variable to the OpenJDK 17 installation directory

Step 5: Verify the Installation

To verify that OpenJDK 17 is installed correctly, you can use the following command:

java -version

This should display the OpenJDK 17 version number

Step 6: Install Java 8 (Optional)

If you want to use Java 8 with OpenJDK 17, you can install it separately. Here’s how:

• Open the Terminal app on your Mac
• Type the following command to install Java 8:

  ./jdk-8.0.2.jdk -i

• This will install Java 8 and its dependencies

Step 7: Verify the Installation

To verify that Java 8 is installed correctly, you can use the following command:

java -version

This should display the Java 8 version number

Troubleshooting Tips

• If you encounter any issues during the installation process, try restarting the Terminal app and trying again
• If you’re using a Mac with an Intel Core i5 processor, you may need to install the Intel HD Graphics 4000 driver separately
• If you’re using a Mac with an Intel Core i7 processor, you may need to install the Intel HD Graphics 5000 driver separately

Conclusion

Installing OpenJDK 17 on macOS is a straightforward process that requires minimal technical expertise. By following these steps, you should be able to install OpenJDK 17 and use it to develop and run Java applications on your Mac. Remember to verify the installation by checking the Java version and the system properties, and to install Java 8 separately if you want to use it with OpenJDK 17.
