This guide's intro has changed multiple times over the years as the landscape has radically altered for the Mac, and after four years, my perspective has changed. It has been continuously updated for over four years and will continue to be updated as long as there is a community to make new discoveries. This is less a how-to guide/manual than it is a roadmap to primary sources by other brilliant people, written to be accessible to both new and advanced users. The information is out there but knowing what is possible, what questions to ask, and where to find it isn't nearly as easy.
