But before that let me tell you that this post is going to get updated in future based on latest technological updates. So don’t forget to subscribe to my email list and bookmark this post for future reference.

After uninstallation process is over you might notice that some of your applications were dependent on Java and they are not working properly. If this is the case with you, then you can reinstall it again or better you stop using them and search for an alternative.

1. Manual Method to uninstall Java

Now you can uninstall Java from your Mac OS in nine simple steps which includes manual deletion of java files and plug-ins on your macOS from several folders which I will show you further. But before you start with the uninstallation process, I would highly recommend you to take a back up of your Mac.

Once you have taken a back up of your system, follow the steps mentioned below:-

1. Close all web browsers on your Mac system such as Safari or Google Chrome or any other web browser which requires Java to function.

2. On the top in Finder, click Go menu and select Go To Folder as shown below in the image.

3. Enter the following path in the Go to Folder menu and click Go:-
/Library/Internet Plug-Ins/

4. Now the Internet Plug-ins folder will open. You have to delete JavaAppletPlugin.plugin from this folder. Right click on JavaAppletPlugin.plugin and you will get an option to delete it. Simply delete it and this will move it to the trash bin. Delete this file from the trash bin also.

Please note that you need to have admin privileges in order to delete this file. If you don't have admin user id and password, you won't be able to delete this file.

5. Now again repeat step 2 and enter the following path in the Go to Folder and click Go.

6. Delete JavaControlPanel.prefPane from the Preference Panes folder. You will need admin privileges for this.

7. Repeat step 2 and enter the following path in the Go To Folder and click Go:-
~/Library/Application Support/Java/

8. Once you have located the Java folder, delete it immediately.

9. Finally empty the Trash bin as you do normally.

Once you are done with all the steps mentioned above you have successfully uninstalled it.
