How To Get Rid Of Mac Jdk Message For Java Commandline Tool

The need to have Java installed on your Mac is needless, to say the least.

I keep getting the message 'To use the 'java' command-line tool you need to install a JDK. Now, to the best of my knowledge, Java isn't on my MacBook Pro (from May 2015). I ported from another computer that had had Java removed although just how I no longer remember. If you’re seeing a pop-up that says “To use the java command-line tool you need to install a JDK” and left wondering “How do I do that?” this is the article for you. For macOS Catalina and higher. Go to Oracle’s Java downloads page. Download the Mac installer. (You want this one: jdk-13.0.2osx-x64bin.dmg. Do not get the one with.

Why may you ask? Because it’s not required for most of the applications on the machine. Besides, if any applications do need it, we can install it then whenever we’re asked.

However, the issue with Java is that it comes preinstalled (without permission) and it is no straightforward task where you can hit an “Uninstall” button just like every other application to remove it.

Now bear in mind that some applications, specifically applications that are Java-dependent like IDEs (if you’re a developer you’ll know what we mean), office suite applications like OpenOffice or LibreOffice, torrent clients and more will rely on Java to work. In any case, after uninstalling Java on your Mac that one of your applications start not to work, then you can always reinstall Java on your Mac.

In this guide, we will show you step-by-step on how to uninstall Java entirely from your Mac.
