Quote:ever heard from Macs?
That's an argumentation that really doesn't hold. (And the same applies for Linux-Desktops as well).
Just because virus-development for Mac (and for Linux) would be a niche-market (due to the
relative nonexistance of these systems in absolut numbers) doesn't mean the OS on those
systems is in any way safer!
There are many holes in Mac-OS and Linux that were open for a very long time ... and in case
of Mac-OS they often remained open even after Apple has been notified.
(Just google the latest problems with PNG-Files and Apple-SW).
So ... it's just a question of time ... sooner or later we will certainly hear from a encrypted MAC.
