"Sure, so why did you say in your first message: "now that Macs are really Intel PCs, ... we'll see more and more [Mac malware].""
Because the article and my post are clearly and specifically about *new* malware. It's obvious that Safari is immune to MSWord macro viri, but it doesn't make it secure.
"No, the article specifically says it's harder to write OS X malware than Windows malware because of the UNIX underpinnings,, and the same applies to Linux."
The article you linked to ALSO says that. Which is a load of bullcrap anyway. Being initially, a long time ago, based on a BSD kernel doesn't make it more or less secure. All Linux distros are based on the same kernel, but some are tougher than others. Same for BSD distros. And re-read it, you will find a lot of the "Macs are more secure because there are no malware targetting them in the wild" flawed circular logic.
"Explain how OS X is gone "downhill" security wise? Leopard is more secure than Tiger !"
I do not know about specific felines, but I can assure you that all the OSX machines I've seen are in the single-user-with-full-admin-rights configuration. With auto-mount and auto execute for external media on. Good default settings, ain't it?
