"The Macintosh has a multi-button mouse, but the buttons are on the keyboard".

You had t press a modifier key to right click, but 2 button mouses have been sold with macs since 10.2 at least, and 10.2 was available in 2001/2.

Control, which still works incidentally.

You still need to enable right click from a menu for Apple-brand mice and trackpads. Otherwise ctrl+click is still the only way

IIRC for trackpads at least it's been enabled by default for some time (though I believe the default gesture is a double-tap rather than a tap in the bottom-right corner).
