i type in texmacs the path of "maxima.sh" by draging this file from the
finder to the terminal window. that is to say :
/Applications/Maxima.app/Contents/Resources/maxima.sh
i seems that this operation launches maxima
it is written this :

now two questions :
- if i type 1+1 then press return (or shift return or page break or others combinations) nothing occurs
Great! Now you have it working. Just type
1+1;
and then <return> (don't forget ; at the end of each maxima command).

So, it seems, the script which is called "maxima" in Linux has the name "maxima.sh" in MacOS.

- where do i tell texmacs that the path for maxima is /Applications/Maxima.app/Contents/Resources/maxima.sh

It would be easier to make a symlink to it called just "maxima" in some directory in your $PATH. After that, typing just
maxima
in a terminal window will start /Applications/Maxima.app/Contents/Resources/maxima.sh.
Of course, alternatively, you can edit a few files in your TeXmacs installation. In Linus, they are
/usr/share/TeXmacs/plugins/maxima/progs/init-maxima.scm
/usr/libexec/TeXmacs/bin/tm_maxima
/usr/libexec/TeXmacs/bin/maxima_detect
(don't know where MacOS folks have put them to).

- more generally, what is the method to install a texmacs extension, like the ones in the list you gave ?
They are not TeXmacs extensions! They are separate programs, some of them surely larger than TeXmacs, and all of them can be installed and used without TeXmacs. But TeXmacs can interact with them, if they are installed. And this is very useful, because you can easily cut-and-paste results from one computer algebra system to another one, etc., within TeXmacs.

Your choice of just 3 programs to which TeXmacs can interface seems a bit random. For example, reduce and axiom (and its forks fricas and openaxiom) are as powerful computer algebra systems as maxima; octave and scilab are powerful matlab-like programs for numerical linear algebra; GNU R is the leading program for statistical analyses; etc. All of them, and more, can be used from within TeXmacs.
