How to Remove Java From Mac

Java is a programming language that is widely used for developing applications and running various software on different platforms. However, there may come a time when you need to remove Java from your Mac for various reasons. In this tutorial, we will guide you through the step-by-step process of removing Java from your Mac.

Step 1: Check for Installed Java Versions

Before you proceed with the removal process, it is crucial to check if Java is installed on your Mac and which version(s) are currently present. To do this:

  1. Click on the Apple menu in the top left corner of your screen and select “System Preferences”.

  2. In the System Preferences window, locate and click on the “Java” icon.

  3. A new window labeled “Java Control Panel” will open. Go to the “General” tab.

  4. Under “About,” you will find information about the installed version(s) of Java on your Mac.

If you have multiple versions of Java installed, take note of each version before proceeding to uninstall them.

Step 2: Uninstall Java

Once you have identified the installed Java version(s), follow these steps to uninstall Java from your Mac:

  1. Open a Finder window by clicking on Finder in your dock or by pressing Command + Spacebar and searching for “Finder”.

  2. In the Finder menu, click on “Go” and select “Utilities”.

  3. In the Utilities folder, locate and open the “Terminal” application.

  4. In the Terminal window, type the following command to list all installed Java versions:

java -version

The terminal will display the installed Java version(s) on your Mac.

  1. Type the following command to uninstall a specific Java version:

sudo rm -rf /Library/Java/JavaVirtualMachines/jdk[version].jdk

Replace [version] with the specific version number you want to remove. For example, if you want to remove Java SE Development Kit 8 Update 131, the command would be:

sudo rm -rf /Library/Java/JavaVirtualMachines/jdk1.8.0_131.jdk

Note: Be cautious when using the sudo command as it gives you superuser privileges. Make sure you enter the commands correctly to avoid unintended consequences.

  1. Repeat step 5 for each Java version you wish to uninstall.

Step 3: Remove Java Preferences

In addition to removing the Java versions, it is advisable to remove any existing preferences related to Java from your Mac.

  1. In Finder, click on “Go” in the menu bar and select “Go to Folder”.

  2. Type in /Library/PreferencePanes/ and click “Go”.

  3. Locate and delete the file named “JavaControlPanel.prefpane”.

Step 4: Verify Java Removal

To ensure that Java has been successfully removed from your Mac, follow these steps:

  1. Open Terminal.

  2. Type the command java -version and press Enter.

If you have successfully uninstalled Java, the Terminal will display a message stating that no Java runtime is present.

In Conclusion

Removing Java from your Mac can be done by following these simple steps. Remember to exercise caution when using the Terminal and double-check your commands to avoid any unintended consequences. By removing Java, you can free up space on your Mac and ensure that you are running only the necessary software for your needs.
