Any hints?
Make sure the xetex binary is indeed in /usr/local/texlive/2007/bin/i386-darwin
or in /usr/texbin, and the XeConTeXt.engine is an executable file
(type "chmod 755 ~/Library/TeXShop/Engines/XeConTeXt.engine" in Terminal.app)
You can also remove the stand-alone slash after "set path=" in
XeConTeXt.engine (it tells tcsh to add the root directory to the list of
directories where executable files are looked for, and that's really
both useless and dangerous).
