There has been a lot of concern over the security of running Java in your browser recently, largely due to a recent bug discovered in the latest update to the Java 7 runtime. Even though Sun has released an update to address the issue, however, the Department of Homeland Security and many cyber security experts still advise users that they’re safer and better off without it.

Fortunately, it’s both possible and simple to completely disable Java from running in any browser on your Mac by following the below directions (via ZDNet):

Step 1

  • Go to the Apple symbol () in the menu bar.
  • Select System Preferences.
  • On System Preferences, type in Java and select the highlighted panel.

Step 2

A new window will appear warning you that the Java settings need to be opened in a new console. This will open. To finish disabling Java, simply:

  • Hit the Security tab.
  • On the Security settings, uncheck the box saying Enable Java content in the browser.
  • Hit Apply then OK.

That’s all there is to it! Java is now dead as a doornail, never to grace your Mac again unless you decide you want it to. Head on over to the original post at ZDNet for additional instructions, including how to disable Java on a Windows-based computer.

    Great. Except that the real Java Control Panel looks nothing like the one in your screen shots and does not have a check box as described, making the article completely inaccurate and totally useless. But other than that, GREAT ARTICLE!! Thanks!!

      You might have an older version of Java. I captured these screenshots after applying the most recent update.
