Hi, On a new Snow Leopard machine, I ran ./first-setup.sh in ~/context. As instructed at the end of the ./first-setup.sh run, I then added /Users/pm/context/tex/texmf-osx-64/bin to my .zshenv, and % echo $PATH shows correct path when I source, logout, restart, etc. I ran: p% texexec example.tex MTXrun | kpse fallback with progname 'context' initialized in 0.001019 seconds I then tried p% luatex sample.tex This is LuaTeX, Version beta-0.50.0-2009122423 \write18 enabled. kpathsea: Running mktexfmt luatex.fmt mktexfmt: No such file or directory I can't find the format file `luatex.fmt'! Any suggestions on what I should do? Also, first-setup.sh creates the dir ...tex/texmf-osx-64/bin, but, p% uname -m i386 Thank you very much for any help you can offer.
