Im running a mac, installed what i assume is the right vinnie folder into my plugins folder, how do i know its working?

Is there a mode i can play without having to be the mayor and manage the budget?

Total noob here, I've created a couple towns, got the basic handle on keeping a small town somewhat sustainable but i feel like im missing out on lots of things, more buildings, different train track/Road curve options etc. Can anyone please point me in the right direction of some good mods, plugins and where to download and then install them on a mac?
