Introduction

Apache HTTP server is an open source cross platform web server which was released under the license of Apache 2.0. It is developed and maintained by an open community of developers under apache software foundation.

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

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.
