"We have removed the KnowledgeBase article because it was old and inaccurate," Apple spokesman Bill Evans, told Macworld. "The Mac is designed with built-in technologies that provide protection against malicious software and security threats right out of the box." Apple, Inc. December 2, 2008
Other articles show that the knowledgeBase article date was merely a normal review of an old article that has been on Apple's website since the old Mac OS days. The Washington Post's Krebs erroneously thought it was a newly posted article. It has been on the current Apple website, substantially identical to the current article, since at least 2002 and the original article number indicates it had originally been created in 1992.
