How to Disable Java Across Your Entire Mac

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.

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.
