Dear all, I've been trying to install the TeX minimals on a new Mac. While MK II works, not so MK IV. I get the error message MTXrun | unknown script 'context.lua' or 'mtx-context.lua' Here is what I did: Downloaded TeXLive 2010 Then followed the instructions at http://wiki.contextgarden.net/ConTeXt_Minimals/Mac_Installation I did this a few years back without a hitch, so I am wondering what is different now. In any case, in the above instructions, under Configuring ConTeXt, instep 4, the copies file has already the indicated changes in it. I used the same paths as indicated and ran luatools --generate as well as context --make Everything went ok without error messages. I then configured TeXShop as explained. As I said, MKII works fine but MKIV gives the error message. I searched the wiki for it and there seem to be some related reports, but I couldn't find a resolution. Any suggestions? If all fails I'll try to clone an older installation. Matthias
