What is Java and why remove it?

Java is a programming language and software platform that allows developers to create software that runs across different operating systems without modifications. It is widely employed in web services, enterprise applications as well as some desktop software.

Although Java is widely used, you might consider disabling it. Here are some common reasons to uninstall Java from your Mac:

• Security risks. Java has a long history of security flaws, which makes it a potential target for cyberattacks and malware.
• Performance issues. Java processes may consume system resources, which can result in slower Mac performance.
• Not required. The majority of modern applications don’t require Java.
• Potential compatibility issues. Certain macOS software or updates could interfere with older version of Java.

Removing Java from Mac manually

Java is not a standard application, so it does not appear either in the Launchpad or in the Applications folders. The only place where you can see it is System Settings.

How to uninstall Java using its installation file:

1. Run the Java installation file. By default, it should be located in the Downloads folder.
2. If you can’t find it on your disk, you can download it from the official developer’s website.
3. Click on the package file.
4. Enter your user password to continue.
   

   
5. In the next window, click the Remove button.
6. In a few seconds, the software will be removed from your computer. You will see a message about its successful removal.
7. Open Finder and press the Cmd+Shft+G shortcut.
8. In the search panel, type /Library and hit Return.
9. Check each of the file paths below for Java-related files. If you find any, drag them to the Trash.
• /Library/Application Support/Oracle
• /Library/Java/
• /Library/Internet Plug-ins/
• /Library/PreferencePanes
10. Empty the Trash.

If for any reason you can’t run the app’s installation file or you face an issue when trying to completely remove Java from your Mac, using the mentioned above steps, don’t worry. You can delete Java right from the System Settings.

How to remove Java from System Settings

1. Open System Settings. You can find it in the Apple menu or in Launchpad.
2. Scroll down the right panel to locate the Java icon.
3. Right-click on the icon.
4. Click Remove Java settings pane.


5. Open Finder and go to the Applications folder.
6. In the Finder’s search field type Java and press Return.
7. Find the JavaAppletPlugin.plugin file and remove it into the Trash.

How to delete Java using Terminal command line

Another way for Java removal is to use a special command in Terminal. Terminal is a default macOS application that you can find in the Launchpad or in the Applications folder.

1. Launch the Terminal application.
2. Enter the following command and press Return:

   sudo rm -fr /Library/Inte*rnet\ Plu*g-Ins/JavaAppletPlugin.plugin
