    I was arguing with someone that OS X has no viruses, and they brought this up ... I am not much of a computer guy so I'm not really sure how to respond to this. Help?

    Tell him that there is no argument. It is a fact that Mac OS X doesn't have any viruses.

    Actually to let you guys know viruses do exist for OS X my uncle runs a couple of networks and one of them is all Macs running OS X server and he said they got shut down once already due to a virus. So there ARE viruses for OS X just not alot and not easy to get.

    I'll believe it when I see it. Microsoft would absolutely love to see a Virus written for OS X.

    Here is how Mac OS X can't have viruses:
    In a version of Mac OS X, I think it was Jaguar, there were some things in some places that aren't there anymore, they are in different places. Also, Mac OS X is very very very difficult to take over. Everything isn't tied into one item like in Windows. Windows is all tied into the KERNEL.DLL file, on Mac OS X, each component is tied to something else. It makes the connections wherease in Windoze all the connections come out of one place. E.G.
    A connects B and C and D and E - Windows
    A connects to C. C connects to B. B Connects to D. D Connects to E. E connects to A. - Mac OS X

    Somewhat kind of like that.

    I heard that OSX can only get a virus if
    1) The user physically clicks the malicious file
    2) Answers yes to the multiple "are you sure" boxes
    3) Enters his/her password
    then and only THEN can OSX contract a virus capible of doing more than making iTunes randomly skip a song (or something meaningless like that) until the user restarts. Then the "virus" goes away.
    On the other hand, when one logs on to the internet (a feat in itself) on a windows PC the computer begins downloading and installing all kinds of spyware and viruses without asking and ends up screwing itself up. Yay!
    Go hackers! Destroy PC civilization as we know it, paving the way for a glorious mac revolution!

    Unless you're running in root mode, you'd kinda have to enter your password for it to access anything important...

    Why are you wearing that stupid man suit?
    Wow, so many "i heard" and "my uncle" and misconceptions about.

    Let's run through this real quick:
    OS X DOES NOT, and probably WILL NOT, have any viruses on it, ever.


    Well, let's take a look:
    1. OS is not built around web applications like Windows is, where it's built ONTOP of (not only DOS, but) Internet Explorer. Everything is an extension of explorer.

    2. To make any system level changes, even when in an Admin account, you HAVE TO enter your name and password. Windows does not ask for this, which is why so much crap gets there.

    3. If you download an application, even in the background, OS X will ask if you want to launch this app for the first time. Right there, is another security check.

    4. The malware out for OS X comes in disk images and packages that pose as REAL applications, or cracks/hacks for those applications. Generally made of applescripts that, again, when trying to run, need your ADMIN password to change things. If you have a funny feeling about something, then do go through with it.

    5. These items cannot self-propogate either. So, in short, your uncle, or what you've heard is flat out WRONG. It is fact that they are wrong, and until the day soeme uber hacker can figure out a way past having to get the admion's password to install it, change system level functions, slap a trojan in the Startup items folder, and get past LITTLE SNITCH (if you don't have this app, shame on you!), then we're in the clear.

    edit: I hear the WOW virus ruins lives, not just hard drives. :D

    I thought I've read there are a few viruses out there for the Mac, but it is by a very rare chance that you'll ever even hear about one. I'm most likely wrong since I heard this a while ago and my facts may be a little out of place... :p

    There will always be a Virus for any OS more than likely, but how the virus propagates into your system is different. OS X is just built right to now allow viruses. It's an un needed program to have anti-virus. With Windows the Registry is the key. Its a major part of Windows, and if they get rid of it with Vista (which they are having trouble with in the first place) then support for previous apps is anywhere from 5% to 0%. Everything uses the Registry in Windows.

    Mac OS X now, it uses XML files - very smart - very good way to go about it.

    Does anyone know if Microsoft is dropping the use of Internet Explorer (technically Explorer...) for browsing your computer, folders, files, etc? If not, then they are just making a big mistake. It's too bad that so many people use IE and have no idea of the circumstances. :(

    I thought they were two different programs that were just tightly integrated :confused: One is called explore.exe and the other iexplore.exe :confused:

    #20 God!

    >>>First... to original poster...if you say OSX can not be infected with a would be lying. Period. And will eventually look very foolish. The rest is up to you.

    Now...this..."some things in some places that aren't there anymore, they are in different places." etc, etc, etc, etc, etc...and the rest of this meaningless babble. FUD. FUD. FUD.. Geez! Slookster...please stop drinking the Apple koolaid. Wery, wery bad.

    Adamance does not make up for substance. Actually..why am i bothering? At least you're right about "Little Snitch"..but that begs the question..why do you need it? Why do you use it?...

    I said that because when I did the cloning, the image had to check the software version to put files in one place over another. It was something that was in Library - I'll have to look when I make another image tomorrow.

    What About Mactels?

    Hey all,

    Don't know much about programming and what not but was wondering if apple's intel switch would render its os vulnerable to viruses? Do the safeguards of OSX (mentioned above) apply even though future versions of the operating system will be able to run/emulate(?) windows software?

    Viruses usually attack an OS, not hardware. So it won't make a difference. Linux for instance is That being said, there are things such as BIOS viruses that can attack the software on your motherboard. Right now Macs don't have BIOS, but they most likely will after the switch.

    Isn't Open Firmware supposed to be the alternative for BIOS, and wouldn't apple want to continue using it (sorry for getting a little off topic here)?
