Rich Mogull with a great article not just on Mac security but computer security in general:

I’m generally unimpressed by any story that involves tricking a user into manually installing malicious software. On occasion we see a particularly creative deception, and I might be concerned if the malicious software was hiding in a mainstream application, but getting someone to install something evil on their system is a fault with the human brain, not their operating system of choice.
