title: Writing to "~/Library/Application Support" folder in Mac OS X 10.7
body: <p>I can use NSFileManager to create a XYZ folder in "/Library/Application Support" in Mac OS X 10.5 and 10.6.  However, in 10.7, it says "You don't have permission to save XYZ in the folder 'Application Support'".</p>
  
  <p>Does anyone know what I can do (e.g. which API to call) to get that permission to create the folder?  Thanks.</p>
