Yes, Apple does indeed have security issues. However, it appears even my low-key assessment of them was overstating the case(s).
The link above will take you to an article at MIT's "Technology Review" web site. It's fairly easy read and I think it's the best depiction of the reality of Apple's security status I have seen. Even if you're not a Mac user, it wouldn't hurt to read this and see something of the differences between the Mac OS X and whatever you are using.
