According to this article in MIT Technology Review, the Apple operating system got it’s very first virus this year. I suppose the “virus-free” label wasn’t going to last forever, but we should still be extremely impressed that it took about five years for a serious vulnerability to be found.
Even with the latest vulnerability announced, I’ve still found the Mac mini I bought last year to be incredibly stable and easy to use when compared to any of the Windows machines I currently use. The only fallout from this announcement I see is that anti-virus software makers will be able to sell more to Mac users.
