You have probably heard of the constant issues surrounding the use of Java on your computer. Although Apple quit installing Java on Mac desktops some time ago, you may have added it yourself to support some app or web site you wanted to use. If it’s on your system, you want it off NOW! There are serious exploits circulating that put your computer at risk if you are still running Java.
Here’s an easy way to check your computer and remove Java if it’s there.
- Open the Terminal app. You’ll find it in the Utilities folder under Applications.
- At the prompt, type this command:
then press the Return key.
If your response looks like this example – stating there’s no Java runtime present – you’re in good shape and don’t have anything to worry about. NOTE: When I executed this command, a window popped up asking if I wanted to install Java. NO! Don’t do it!
If your response identifies a version number – probably either 1.6 or 1.7 – then you need to open Finder, go to the /System/Library/Java/JavaVirtualMachines/ directory and delete it. Then, empty the Trash.
