Howdy,

I assume you have a root file (e.g., mybook.tex) that then contains \include or \input commands for the chapters. if so, then place the line

% !TEX root = path/to/mybook.tex

at the top of each chapter file (that way TeXShop ``knows'' where the root file is located). For example, if you have the root file in a folder and each of the chapter files is in a sub-folder of that folder you can write

% !TEX root = ../mybook.tex

at the top of each of the chapter files (.. means go up one folder). If they all reside in the same folder you'd write

% !TEX root = mybook.tex

and it will all work.

Good Luck,
