Dear Hans, Otared, Thank you for your concern. The version of luametatex is 20191206. I followed what Otared said, but texmf-cache is not created after mtxrun. "context —make" is running, but no format. I checked folders after the installation. Folders, texmf-cache, texmf-fonts, texmf-local, texmf-modules, texmf-project are empty. texmf folder contains {fonts,metapost, tex,web2c} texmf-context folder contains {colors,context,doc} However, I couldn’t find base files, script files, etc. Is it normal? Is it related with Catalina? Have a nice weekend.
