As you don't have the echo message we can be pretty sure the problem is
*not* the same as the failure to launch Safari when trying to use the
Denemo manual - in that case Safari was launched, it just didn't expect
a URL on the command line, expecting a file name instead (so you could
fix that by a script that chopped the initial file:/// off).

I've looked at the source code and it seems the problem is that for
some Glib versions the success status of the typesetting is being
I've fixed this now in the sources, but unfortunately I don't think
there is any daily build for MacOS - indeed I'm not sure if anyone is
ready, willing and able to build for MacOS - so you will need a work
around. You may be able to get there by locating the temporary
directory where Denemo is storing the results of typesetting. On Unix
it is /tmp/Denemo_*
a new one of which is created each time you start Denemo. In there you
will find the .png files that are created (they are named
denemoprintA.png and denemoprintB.png alternately).
