At long last Lilypond and TeXShop are working together on my
system. The problem solving process was time consuming and
difficult. Many thanks to the folks of the TeXShop forum, including
one of the program authors, who spent much time and effort helping me.
I shall try to summarize how it was done as best I can. I shall
leave any elaborations or corrections to those more knowledgeable.
1. An engine must be installed. This engine can be found at:
http://www.dimi.uniud.it/~vitacolo/download/software/latex/Lilypond-
LaTeX.engine.txt
2. The engine should be saved as a text file, and installed in
the folder Library/TeXShop/engines
3. Change the name of the engine to Lilypond-LaTeX.engine
Be sure to eliminate the txt part. Be sure to use the correct
capitalization.
4. Put a copy of the latest stable version of the Lilypond
application in Applications. To make things easier, do not put it
inside a folder, but only inside Applications. Otherwise, you will
need to get inside the engine and alter the path, a process which
can be messy.
5. Open TeXShop. If it was already open, close it and re-open.
Open your source file.
6. In TeXShop, in the pull-down menu, chose the option LaTeX-
Lilypond. If this option isn't available, then the engine is not
installed where it needs to be, or named properly.
7. Add the following as the first line of your source file:
%%!TEX TS-program = Lilypond-LaTeX
Be careful to use the correct capitalization. Also, the TeXShop
text editor will turn this code red.
8. Be sure that Lilypond is written in lower case in your source
file. For instance: \begin {lilypond} and \end {lilypond}
9. Before compiling your source file, make the engine
executable. To do this, open the Terminal, and type (This is three
different codes, so press "Enter" after each line):
cd
cd Library/TeXShop/Engines
chmod 755 Lilypond-LaTeX.engine
10. Compile your source file. If your biorhythms are high today,
it should work.
Some Problems I Encountered
Turning the engine source code into a correct engine file was a
problem for me. Here is what I did. I copied the code from the web
site into Microsoft Word, and saved as Text Only. I was told that
this is not a good approach since Word adds garbage code, even to a
text-only file. Nevertheless, this was the only option I had
available. I shall leave it to others to offer a better approach.
The solution to this problem was to open the Terminal and input the
following:
perl -pi -e 'tr/\015/\012/' Lilypond-LaTex.engine
(I'm wondering if the capitalization is incorrect in the code above).
This apparently eliminates the garbage code. I'll leave it those
more knowledgeable to explain further what this did.
The Lilypond-LaTex engine should have a blank icon, like the icons
for the other engines in the folder.
I hope this helps. Good luck everyone.

If it helps, here is my current TeXShop source file. The output is
beautiful, and the time and effort to get this working was well
worth it.
%%!TEX TS-program = Lilypond-LaTeX
\documentclass [12pt] {report}
\usepackage {times}
\usepackage [dvips] {graphicx}
\begin {document}
\begin {flushright}

\begin {center}
Brahms: Intermezzo In A Major\\
\emph {Op. 118, No. 2}
\end {center}
\begin {lilypond}
{
\key a \major \time 3/4
<< { cis''8 fis'' e''4 d'' cis'' b'8 d''8 gis'' fis'' b'4 a'8 cis''

e' dis' r4 cis'4 } >>
\bar "||"
}
\end{lilypond}
In this example, Brahms's personal style of canon writing can be
seen. The canon has been extracted from the rest of the texture.
