I hope for your sake that you don't really believe that. There are a lot less viruses and other malware written for Mac OSes, mostly becausre the potential target base is so muxh smaller. As the number of Macs grows, so does the amount of malware written for it. There are some nasties out there just for Macs, and if you do trust in Mac's "immunity" you will be disappointed.
