You would be wrong. Macs have supported multibutton mice for over a decade now. ALL new Mac desktops ship with a two button mouse (yeah, it doesn’t look like it has two buttons, but it does). The laptops have only one physical button (for a reason that takes entirely too long to explain but it makes sense), but since most people tap the trackpad on laptops to click instead of using the button, it’s no loss. With the laptop trackpad, tap it with one finger to left click, tap it with TWO fingers at the same time to right click.
The Mac (pay attention to the capitalization, please, a MAC is a Media Access Controller aka a network chip) isn’t one-button-limited. I’m posting using Mac OS X right now, and next to my Apple keyboard is the same Logitech 2 button optical scroll mouse I’ve used on Mac OS for years.
Since you mentioned my fracturing the Mac acronym, what do UAC and NTFS stand for?
