[HAL9000]

My point is that there isn't anything inherent in the Mac OSX that prevents or eliminates viruses.

That statement is simply untrue.

Unlike Windows, the inherent design of Mac OS X is intended prevent malware from getting installed. So far, the hackers have failed in every attempt to spread a Mac virus, even though most Mac users don't use anti-virus software.

What, specifically, is in OSX to make it virus proof?
