I guess this page explains what's going on technically:


"Apple has started abstracting the idea of a system font: it doesn’t 
have a publicly exposed name. They’ve also stated that any private 
names are subject to change. These private names all begin with a 
period: the Ultralight face for San Francisco is named 
“.SFNSDisplay-Ultralight”. To determine this name, you need to dig 
around in the font instances returned by NSFont or UIFont; it’s not 
easy by design....As a part of this abstraction, there’s now a new 
generic family name: -apple-system. The markup looks like this:

body {
   font-family: -apple-system, "Helvetica Neue", "Lucida Grande";

Unfortunately, it’s very poorly documented. Most of the information 
I’ve found about this name comes from the WebKit source code."

I wonder if there's a way to add a "System Font" item to the font 
selection menu, so we can set the system font as the preferred font 
without using Terminal to delete settings?
