Well you didn't present the secret handshake that would open immediate 
access to such information.

Actually, it was probably not brought up earlier as it's kind of an 
unsaid list etiquette rule exercised by some not to critique someone's 
choice of APIs unless specifically asked for.  Most will try to 
directly address your questions or problems no matter what APIs you 
chose.  It can be somewhat rude to flat out say your choice of APIs is 
folly, and sometimes presumptuous that the specific APIs were not 
chosen for reasons undisclosed in the original problem.  If you're 
open for API alternatives you can state so with something like "...is 
there an easier or more reliable way to do this?".  Otherwise some 
will assume you have your reasons and will do their best to help make 
the chosen APIs work for you.

NSWorkspace is an oft-overlooked class that contains many useful 
external utilities.  The class name doesn't exactly scream URL 
launching or icon fetching, ect.  Though I'm not sure what name would 
completely describe NSWorkspace's broad ranged functionality.
