Dear Dalyoung, Thank you for the good news! Now I will add to the wiki the procedure I described, which you followed, but we have to find a way for people to get a zip file containing a complete tree of LuaMetaTeX which can be installed « by hand » under MacOS 10.15 Catalina. Maybe Hans or Mojca have a suggestion in this regard. Best regards: OK

Dear Otared,

I followed your instruction. During the process, “mtxrun —generate” and “context —make —all” work well.

After rebooting the system, “context test.tex” produces a pdf output finally. Wow! It is a long way around, but I learned many things.

Thank you for your help.

Best regards,

Dalyoung
