Multiple addons using the same name (OS X) I got an error message in User Preferences > Addons tab

Multiple addons using the same name found! 
likely a problem with the script search path. 
(see console details)


But under OS X I don't see "Console" item on the list as Window users.
How can I found duplicated add ons on mac?
To see what Blender thinks, you need to run Blender from command line.


Open Terminal application
Write cd then hit spacebar and drag&amp;drop your folder with Blender into Terminal window
Enter
In Terminal window write ./blender.app/Contents/MacOS/blender
Enter


Then if you open Blender's "User Preferences" tab "Add-ons", Terminal displays all conflict add-ons.

(There is also patch to show these add ons directly in User Preferences window https://developer.blender.org/D791 for better future)
