The problem is, I think, with the grep line:

My maxima script does not contain "list-avail", and yet it accepts the --list-avail option

This is really disturbing. Your maxima script looks quite different from what I have on Linux. It contains, near the end, after a long list of possible lisps with the corresponding "exec ..." lines, the following:

else
echo "$0: lisp=\"$MAXIMA_LISP\" not known. Use --list-avail to see possible
options." >&2
exit 1

Your version contains just one possibility, "exec sbcl ...", and no "else".

Is this maxima script the standard one on macs? If so, maxima_detect should be re-written again, to take into account such possibility.

The history is following: in maxima-5.9.0 the option --list-avail appeared; it was implemented directly in the shell script, and, naturally, the string "list-avail" was present in it. Later, the functionality was moved to the lisp layer, but the string was still present in the script "maxima", so, the test in maxima_detect continued to work. If there is some widely used maxima package for mac which installs the script without this string, we should find a way to detect this variant.

By the way, the latest TeXmacs is 1.0.7.3, but 1.0.7.2 is certainly new enough.
