The emergence of a serious malware construction kit for the Mac OS X seems to mimic a 2008 prediction by a security researcher. The paper used game theory to predict that Macs would become a focus for attackers as soon as Apple hit 16 percent market share. Three countries — Switzerland, Luxembourg and the United States — have Mac market share around that level. Apple — and many Mac users — argue that Mac X has a special recipe for security that makes it less likely to be infected with malware. Many security researchers counter that the Mac’s seeming immunity stems from its security.”]
