Countless people have switched to Macs because they want to stop worrying about viruses, spyware, and other threats so common to PC users. According to conventional wisdom (and even some Apple marketing), Macs are inherently much safer than Windows PCs — and, sure enough, millions of people use Macs every day without incident, having never given a moment's thought to security.

And yet, curiously, some guy seems to have come up with enough to say about Mac security to fill a rather thick and heavy book. How can that be? Are Macs really as insecure as other computers — and are Mac users a bunch of blissfully ignorant folks on the fast track to digital oblivion? Or are the supposed security risks to Mac users nothing more than fear-mongering on the part of an overzealous publisher?
