Dear Mojca,
"texmfstart texexec --make (--xtx) --all" run smoothly, but luatools still has a cnf error.
Did you update the scripts in binaries as well? (Unless you updated ConTeXt from TL repository, it will keep the old mtxrun in binaries, and that one doesn't work at all.) Mojca I upgraded MacTeX using "tlmgr updarw --all" first. And then, texhash texmfstart texexec --make --all texmfstart texexec --make --xtx --all It's working good. But, I try "luatools --generate", then error messages are appreared. luatools --generate LuaTools | error unable to identify cnf file LuaTools | error unable to identify cnf file LuaTools | no cnf files found (TEXMFCNF may not be set/known) LuaTools | LuaTools | runtime: 0.002 seconds Should I run .luatex(containing "export $texmf= ... ", etc) as before to set environment? Thank you for your help. Best regards, Dalyoung
