The chief reason for absence of Mac viruses is neither better security, nor a better quality of users. It's simply that Apple has less than 5% of the market share, and that less than 5% percent is not in any crucial area. This has two consequences. First, the pool of potential authors of malware is much, much smaller than for Windows. (Possibly, this is even further restricted by the higher-income demographics of that tiny fraction of the market.) Second, there is virtually no incentive to attack Macs. What most malware authors crave is notoriety, if not for themselves at least for their products. There is no notoriety to be had in attacking Macs. Write a worm that cripples Mac e-mail systems, and you might make page 40 of the New York Times -- if your masterpiece is particularly nasty. Forget about CNN or BBC anytime, let alone primetime. Write one that buggers Windows -- and the whole world will be talking about you. f
