The hardware and software are built together from the ground up. That's why there fewer problems with Apple than Windows machines. Of course the paucity of worms written for OSX is due in no small part to Apple's small market share. As the Mac Mini becomes more popular, that will change. But its hard to write a virus or a worm for a UNIX based OS since there's no registry to write to and save information.

Of course the paucity of worms written for OSX is due in no small part to Apple's small market share.

There is no "of course" about it. The installed base of OS X is now over 18,000,000 (25,000,000 if you accept Newsweek's survey) and worms and viruses have been specifically written for much smaller installed bases than that. OS X has been in the wild now for over 5 years and we still have not seen its first virus or worm.

The real reason is the extreme difficulty of writing a self-propagating

malware for a machine that requires permissions to install and then again to execute for the first time... it's all about a lack of vectors that would allow the malware to spread.
