Installing Java for macOS: A Step-by-Step Guide

Are you experiencing issues with installing Java on your Mac? If you don't currently have Java installed, you'll soon receive a message saying 'No Java runtime present, requesting install.' followed by a popup message asking you to install a JDK. In this article, we'll walk you through the process of installing Java on your macOS device.

Step 1: Get the Yosemite Compatible Java 8 Installer from the Command Line

If you want to install a more recent version of the JDK or JRE, you can download it directly from Oracle. However, note that this version installs fine in OS X Yosemite despite having an older icon. It's actually JRE 6, which is not the most recent version.

Step 2: Grab a Yosemite Compatible Java Version from Apple

Apple offers an older Yosemite compatible version of Java on their website. This version may not be the latest, but it will work with your Mac. Simply download and install it to get started.

Security Settings for Eclipse

When trying to launch Eclipse, you may encounter security settings that prevent it from launching. To bypass this, right-click on the eclipse file and select 'Open.' Then, open a terminal in the Capella folder where it was moved and type 'chmod +x Eclipse.app/Contents/MacOS/eclipse.'

Unzip and Move the Capella Folder

To avoid security checks that may prevent Capella from running, unzip the MacOS Capella bundle and move the Capella folder to a different location.

Download Capella for Mac

You can download Capella for Mac from here. Make sure to install it correctly and follow the instructions provided.

Install Java 1.8 64 bits

Ideally, you should install Java 1.8 64 bits, which is available for download here. This version should work seamlessly with your Mac.

Uninstall Other Java Versions (Optional)

If you have other versions of Java installed on your machine, it's a good idea to uninstall them to avoid conflicts. Simply follow the instructions provided by Oracle or Apple to remove any unwanted Java installations.

By following these steps, you should be able to install Java correctly on your Mac and get started with using Capella. Remember that many Mac users no longer need Java, so if you're unsure whether you need it, you may want to reconsider installation.
