OK, yeah, this is a newbie question, but why is it that leopard doesn't get viruses? I've always heard that it's just because Leopard is not used by as many people as windows and virus designers have a larger incentive to go after windows. Does Leopard ever get viruses? Will there be a tipping point where we all of a sudden get a massive wave of Mac viruses? Should I install an anti virus program on my gorgeous, beautiful new MBP Classic?
