TeXShop ⇒ nomencl and engine in TexShop

[viga01]

Hello,
I am trying to make the nomemcl package working using TexShop. From another forum http://tex.stackexchange.com/questions/ ... or-nomencl, I read that I need to create an engine in the folder
~/Library/TeXShop/Engines/

However the folders /TeXShop/Engines/ do not exist. The engines must be located somewhere else, but even with a search of hidden files and folders, I can't locate those engines files.

Thanks for your help!
