Everyone should be security aware.
I would like to take time to point out something Erik left out of the Mac security equation. There is a very important difference in the Mac OS (any version old or new), which is that 90% or more in built into the HARDWARE and is not loaded from the hard drive, but from ROM (read-only-memory). Thus the major percentage of the operating system cannot be changed by hacking or a virus.
My experience with Macs goes back to the first 128K in 1984. Can a Mac become infected? YES After all this is how Peter Norton made his debut with Norton Utilities and Norton Anti-Virus. Can an Infection take down a Mac? Not seriously because the only portion of the Mac OS that is loaded from the hard-drive is the tokenized or localized software. I.E., the keyboard language set for whatever country you live in. Very minimal stuff. With a clean copy of your Mac system you can easily restore even that portion and be up and running again quickly.
Some comments already posted are grossly unaware of just how many Macintosh computers are actually in use compared to PCs. This is just more of the age old Ford vs Chevy war.
Apple Computer has done a tremendous job of building better computing devices than any other single company on the planet.
They maintain strong market shares in every arena they dabble in and ALSO hold on to loads of reserve CASH for development of future devices.
But for those who do not want the BMW of computers, or simply cannot afford one, go ahead and buy the Chevy.
Obviously, I also own a Ford!
