There are plenty of PoC ones just waiting for the OS to get some tiny amount of popularity - so keep the AV up to date...
OSX has had its fair share of security flaws though (as has Windows/Linux/Solaris/HPUX)
AFAIK, none of the PoC types yet shown will work without admin password entry to authorise it.
and significantly fewer flaws than Windows... and many of those that have existed, were actually related to M$ software.... even back in OS7.5/8/9 the few viable security flaws were largely to do with M$ explorer and mail apps/. the other weakness exploited was the hypercard system.
the ONLY pure Mac virus i've ever encountered in the wild was one called Seven Dust... back in pre-OSX days.
I've provided support for several hundred professional Mac based AV systems........ 1 virus in all that time... one one machine only....
Paul M,
I should own up and admit i use, and support, both major Platforms for work..... which is in the Audio-Visual industry
OSX is generally more responsive under our normally heavy work load conditions than Windows.... this we've tested on both the same intel based hardware, and comparable previous systems between PPC and intel hardware
it is however not perfect...... if it was, i'd probably not be sitting here typing this........
and believe me, Apple have almost as much of a "Screw the users, we're like, some kind of nerds god" complex as M$
I trust Steve Jobs as far as I can throw his office building or bank balance...
to be honest, i'd probably trust Bill Gates more......
But damn it, Apple just keep building products that work well enough and reliably enough to keep me, and many clients, coming back for more.
but also because they keep buying the software companies we rely on.., and switching off the PC versions.....
it's not all roses , fine wine and pretty women in the Orchard.....
