Beamer
Although Prosper is really popular for those who prefer to make slides with LaTeX, it is not so appealing to Mac OS X users. It is just because Prosper uses ps files.
Contrary to Prosper, Beamer dicretly works with pdf files. This seems to be more attractive to Mac OS X (and TeXShop) users.
Download Beamer (and also pfg and xcolor) from https://sourceforge.net/projects/latex-beamer/.
Place those components in
~/Library/texmf/tex/latex/beamer ~/Library/texmf/tex/latex/pgf ~/Library/texmf/tex/latex/xcolor
respectively.
On Terminal.app, run
mktexlsr.
