Hi! I have little problem with TeX, when I use It under MacOs. I have installed TeX Live 7 under MacOs 10.2 and MacOs 10.1.5. When I try run TeX I receive: This is TeX, Version 3.14159 (Web2C 7.3.7x) kpathsea: Running mktexfmt tex.fmt fmtutil: config file `fmtutil.cnf' not found. I can't find the format file `tex.fmt'! How I can repair this ? ERt
