Re: OS X security?
"That "clean slate" was actually an operating system first released in the 1980s, and containing large quantities of code from the late 1970s. Unix -> BSD -> Mach -> NeXTSTEP."
Of course it's well known than OS X is derived from Unix. The point is Apple had the opportunity to start afresh but their eventual solution contained vulnerabilities that could've and should've been anticipated in the year 2000. Instead we got a deluge of hollow boasting in their marketing material about how Macs "just work" and never get viruses etc.
