Once youve installed it, it installs deep inside OS X and its there for good so the best advice is dont install Java on your Mac unless you 100 need it However, the good news is that you can completely disable it in just one move so that it cant cause any further problems on your Mac.

Note that the official Java uninstall instructions for Mac from Oracle only disable Java they do not actually remove Java from your Mac.

They are also a bit complicated to follow if youre new to Macs as it requires using Terminal commands in OS X.

Java For High Sierra How To Use Terminal

Then we show you how to use Terminal to remove as much of Java as possible from your Mac.

Go to the root Library folder in LibraryInternet Plug-Ins and delete everything related to Java.

To access your root Library folder, open Finder and click on the Go menu at the top.

Hold down the Alt key (also known as the Option key) and you will see the Library folder appear: Once youre in the Library folder, delete absolutely everything related to Java.

If you also had the JDK (Java Development Kit) installed, you also need to navigate to LibraryJavaJavaVirtualMachines and delete anything that you see.

Then go back to your Mac desktop and click on your Macintosh HD and go to your SystemLibrary folder and delete everything related to Java there too.

This instantly disables Java on your Mac and prevents it from infecting your Mac in any way via Java applets in websites or apps.

Note that you should quit and restart any browsers you had open and you can surf safe in the knowledge that Java cant do any harm to your Mac.

However, first you need to disable a new layer of protection to OS X 10.11 that Apple has added called Rootless SIP.

In Terminal type: csrutil disable Hit Return and then restart OS X.

Your Mac will then restart with SIP disabled and you can try installing Java again.

All you have to do is follow the same instructions as for disabling it except instead of csrutil disable you type: csrutil enable Even after this, there will be traces of Java files on your Mac in other locations (such as usrbin) but you really dont need to worry about them as removing them can mess up OS X.

You can double check whether Java still exists in your system by typing java -version in Terminal and it will show you exactly which version of Java you have installed.

Note that Java version numbers are a bit confusing because what are installed on your system as Java 1.6, 1.7 and 1.8 are known more commonly as Java 6, Java 7 and Java 8 respectively.

Note that if youre trying to install Java 6 on Mac (called Java 1.6 by Oracle) and you keep getting the error message: A newer version of Java is already installed Make sure that you are downloading the correct version of Java 6 from the Apple website which currently is Java for OS X 2015-001.
