I did everything you mentioned, but i reopen lyx and go to document settings and
in document class  beamer is not an option.

If I go to Tools and Tex Information there it appears and it shows me the path where it is
and everything. What should I do?

Hi, thanks for your response.

I do have lyx, but beamer is not a class. I already downloaded beamer
but I don't know where I need to put it and how to install it so that
it works with lyx.

Does anyone know?
This will depend how LaTeX is installed. Search for the file
"article.cls". Let's say you find it in
/usr/share/texmf/tex/latex/base/. Then you can put beamer.cls and all
the *.sty files in there if you wish, but it's better to put them in,
say, /usr/share/texmf/tex/latex/beamer/, which you'll have to create.

Better yet, you can create a "local TeX tree" under your home directory.
This local tree won't get overwritten by upgrades, etc, so it's a good
place to put anything you download yourself. Where it goes is determined by the texmf.cnf configuration file. There are some remarks about how to
read it, etc., in the Customization documentation (Help>Customization,
section 5.1). Find this file and then look for the definition of
TEXMFHOME. It's usually $HOME/texmf or something similar. Suppose it's
that. Then you can put beamer.cls and the *.sty files in
$HOME/texmf/tex/latex/beamer/, which again you'll have to create. Note
how the structure of the local tree mirrors that of the main tree. This
is important. The documentation you could put in
$HOME/texmf/doc/latex/beamer, say. Check out your main tree
(/usr/share/texmf, again, or something close to that) and see where your
distribution has put similar things.

That said, I think that the Mac LaTeX distribution includes some sort of
"package installer" that will download and install packages for you.
