Hello. You may take a look at this library 
https://github.com/MyLittleRobo/standardpaths
OSX version uses Carbon though. You may want to use Cocoa API 
(which is newer), but it's Objective-C.
Also you may consider standard path for data storage without 
using any api or spec. It's usually $HOME/Library/Application 
Support/ on OSX.
