Hey there John,
I believe that the LilyPond engine is now included automatically in the
TexShop distribution, so the Italian university link is moot (it’s where you
used to have to download the engine from.) Here’s what I did, quoted from a
discussion on this list this past summer:
"Inside the TeXShop Package (Contents>Resources>TeXShop>Engines) there
is an “Inactive” directory. If you look inside there, you’ll see a
LilyPondEngines-2.1.0b directory, with LilyPond.engine and LilyPond-Book.engine
inside. Move those from the Inactive directory up to the Engines directory,
restart TeXShop, and you’ll have LilyPond and LilyPond-Book alongside all of
your other engines in TeXShop (LaTeX, XeTeX, BibTeX, etc.)
Also inside that LilyPond engines directory is a README.txt file, which
actually has instructions on how to enable point-and-click!”
