It’s being reported that the newest version of Mac Flashback Trojan can now exploit Java engine in Mac OS X, all versions of Mac OS X I guess. It bypasses the administrator privilege protection, and so it can install itself onto any Mac machine with Java enabled without the need to use an administrator password. As now, Apple has yet to release a security fix to counteract Mac Flashback Trojan’s Java exploit, therefore I think it’s best for you to disable Java plugin for your browsers!
Should you disable Java on Mac altogether? Yes, but unfortunately Java is so interconnected with Mac OS X (all versions), therefore I do not yet know how to disable Java on Mac. If you know, please write a comment or two and share your knowledge with my blog’s readers. Anyhow, the easy quick fix for now is not to use Java in any browser that you use on Mac.
Without further ado, now I’m going into how to disable Java on the most popular browsers that you can use on Mac. These browsers will have to be Safari, Firefox, Chrome, and Opera! So check the instructions below…
- Safari – disable Java, you need to go to Safari > Preferences > Security > and uncheck the box that says Enable Java.
- Firefox – disable Java, you need to go to Tools > Add-ons > Plugins > and disable the Java Applet Plug-in plugin.
- Chrome – disable Java, you need to type in about:plugins in the browser address bar and disable the Java plugin.
- Opera – disable Java, you need to go to Tools > Advanced > Plug-Ins > and disable the Java Applet Plug-in.
