Howdy,

Yes it does! The !TEX tells TeXShop to use one of the internal engines to typeset the file (if you use typeset->Typeset (Cmd-T) while the !BIB tells TeXShop to use the designated program, in the designated TeX binaries directory, instead of bibtex when you run Typeset->Bibtex (Shift-Cmd-B).

Good Luck,
