Thank you, much appreciated! I always wondered if the decision to only have one fire button in Q3A was based off its compatibility with Mac OS, and thus a lack of a second mouse button. Other FPS at the time (e.g. Unreal Tournament, Half-Life) usually had a secondary fire button to allow for alternate weapon functions (e.g. grenade launcher on SMG, zoom on sniper rifle/crossbow, etc), which was mapped to the right mouse button.

Seems unlikely, since Q3A used all the mouse buttons on PC by default, just like in previous versions of Quake. Those games also don't have secondary firing modes, Q3A is supposed to be a sort of ultimate refinement of Quake deathmatch.

No, secondary weapon functions were never a q3 thing. They wouldn't have nerfed the game for OS X regardless, especially not when you could just plug in a PC mouse or rebind the controls to use some other key.
