Good Day All!
I've searched & searched for the answer to a puzzlement and managed to get quite confused.

Is Java safe to have on the Mac running OS X 10.6.8? Should it be disabled in the operating system and the browsers, just the browsers or neither one?

Is JavaScript safe to have on the Mac. Should it be disabled?

I do have one program that requires Java to run (CrashPlan). I'd also assume lots of web sites need one or the other.

I apologize for asking a basic questions, but my searching revealed answers ranging from "It's All Good- No Worries" to "The Bad Guys Are Going To Get You If You Have Either".

I this forum, search results for JavaScript came up empty and for Java, too. But, I know they must be here somewhere.

This is the place for real & knowledgeable answers, so here I am!
Thanks Very Much!
Paul

Seems to depend mainly on the version of Java you have installed. Have a read of this link:-


About the security content of Java for Mac OS X v10.6 Update 12

Hang on to those original install discs like grim death! Using OS X.7 or later make a bootable USB thumb drive before running Installer!

Thank You Harryb2448.
That is an interesting article. Java Preferences.app on my computer shows 1 .6.0_65-b14-46A in both 32 and 64 bit versions.

The article addresses 1.6.0_37
So, based on the article, am I correct that it's OK to leave Java enabled?
Thanks Again,
Paul

My advice - if you don't need Java, disable it. It doesn't create a gaping hole on your machine or anything but disabling it does add a tiny bit more security.

As for JavaScript, you don't have it "on your Mac" per se - the runtimes are built into applications (primarily web browsers). You can disable each browser's JavaScript execution if you want but if you do, you're going to have a bad time on the web. For example, this page loads 22 external JavaScript files not to mention the JS built into the page itself.

Thanks VanSmith for your reply.

Your words explained what's what & who's who quite thoroughly, thus clearing up my confusion.

I appreciate your help and your help, HarryB2448. I learned quite a bit today. It is always a good day when something is learned.

Enjoy Today!
