Hi, I tried to update luametatex which was running well(it was installed following the process in the wiki>installation> MacOsX catalina), but I got the following error after all the files are downloaded. resolvers > lua > loading file '/Users/graph/ConTeXtL/tex/texmf-context/tex/context/base/mkiv/math-spa.lua' succeeded tex error > tex error on line 2960 in file math-ini.mkxl: ! Undefined control sequence l.2960 \normalsupmarkmode \plusone % 2 also disable ^[^+] in text mode <empty file> The control sequence at the end of the top line of your error message was never \def'ed. You can just continue as I'll forget about whatever was undefined. resolvers | formats | resolvers | formats | binary path : /Users/graph/ConTeXtL/tex/texmf-osx-64/bin resolvers | formats | format path : /Users/graph/ConTeXtL/tex/texmf-cache/luatex-cache/context/5fe67e0bfe781ce0dde776fb1556f32e/formats/luametatex resolvers | formats | luatex engine : luametatex However, the installation continues to end. But the same error appears when I compile a tex file. *********** resolvers > lua > loading file '/Users/graph/ConTeXtLM/tex/texmf-context/tex/context/base/mkiv/math-spa.lua' succeeded tex error > tex error on line 2960 in file math-ini.mkxl: !
