Java JDK 8 Download for Mac: A Step-by-Step Guide

In recent years, the Java Development Kit (JDK) has undergone significant changes, with version 64-bit becoming the default installation on all systems since 2017.1. This article will provide a comprehensive guide on how to download and install Java JDK 8 on your Mac.

Understanding the Default Installation

By default, the 64-bit JDK is bundled with all product installers. It is recommended to use this provided JDK version unless you encounter specific issues that require a different configuration. If there is no jbr subdirectory in the IDE installation directory, reinstall the product and ensure that there are no environment variables overriding the default runtime.

Accessing the Choose Boot Java Runtime for the IDE Dialog

To change the runtime or troubleshoot issues with JetBrains Runtime, you can access the Choose Boot Java Runtime for the IDE dialog. This option is useful for isolating and fixing problems with the runtime or checking if an issue is specific to JetBrains Runtime.

Adding a New JDK

If you need to add a new JDK, specify the home folder of the Java 17 installation on your disk. You can select one of the already installed JDK 17 options or click Add JDK to continue with the process.

Troubleshooting Issues

If the JDK version in the About dialog doesn't match or didn't change after attempting to install a new runtime, follow these steps:

1. Verify via the About dialog that the new runtime is used.

2. Restart the IDE to try the new runtime.

3. Click OK and wait until the file with JetBrains Runtime is downloaded and configured.

Installing Older Runtime Versions

It's essential to note that installing older runtime versions may render your IDE unusable or introduce new issues. It's recommended to install the most recent version or the version you were asked to try by JetBrains staff.

In this article, we have provided a step-by-step guide on how to download and install Java JDK 8 on your Mac. By following these instructions, you can ensure a smooth installation process and troubleshoot any issues that may arise with your IDE runtime. Remember to always use the recommended JDK version for optimal performance and stability.
