"Ignorance can be cured" Redux! (SM, I should have pinged you on the last post to the Clinton guy. my apology for improper form.)
I guess you haven't bothered to read this thread, huh? Macs are SECURE against the numerous ATTEMPTS to infect them. As of now, there are NO (read that as ZERO) successful attacks on OSX/any version.

Do you really think you fool anyone with "WE may need it on the mac some day"?
Do you understand the meaning of FUD?
