The short of it is: it just won’t work. So for instance if I type “5+2” then invoke Edit/Math/CAS, I only get a lonely = side to the right of the expression, and no result (see screenshot) I am currently running Lyx 2.2.0 on Mac Os Sierra, but I had exactly the same problem under Maverick and El Capitan with previous Lyx versions, namely, nothing happens. I have specified the paths correctly (I think) to where the apps are (Mathematica, Maxima, Maple - nothing seems to work), and I can see the software calling the app (math-extern maxima), or (math-extern mathematica), but no result is churned out. Here is what I have in the "PATH prefix" field under Lyx->Preferences->Paths: /Library/TeX/texbin:/usr/texbin:/sw/bin:/sw/sbin:/opt/local/teTeX/bin:/opt/local/bin:/Library/TeX/local/bin:/Library/TeX/bin:/Library/TeX/X11R6/bin:/Library/TeX/sbin:/sbin:/usr/local/sbin:/Library/TeX/usr/local/bin:/Applications/Mathematica.app/Contents/MacOS/MathKernel:/Applications/Maxima.app:/Applications/Maple 18/Maple 18.app Can anyone please help? Many thanks, Paola [cid:1CA68732-253E-465F-82E6-7DF587AC9DB0@st-andrews.ac.uk] I'd try calling lyx with '-dbg mathed' parameter from a console window. Alternatively use View->Messages Pane->Settings Check 'Selected' Double click on 'mathed - Math editor' back to 'Output' ... calling: maxima input: 'simpsum:true;tex(5 + 2);' output: '7' Buffer.cpp (3449): updateMacro of novýsúbor9.lyx 12:31:27.889: Automatický úklad hotový.
