I agree with you regarding the overwhelming availability of MS vs Mac for targeting. Sure it’s more difficult to attack Macs, but not impossible. One day a very good hacker is going to write some scripts and tools for use against the Mac, and when it happens there will be much wailing and gnashing of teeth by all those Mac users who didn’t practice ANY kind of computer security because they felt safe.
No matter the platform, OS, or other security provided by your network, ALWAYS distrust unknown/unverified information be it an email or a website or anything else.
That is all I’ve been saying....
