But when I did this just now on a file, I got a box saying that this file cannot be unlocked, but I can duplicate it and edit that.  If I do so, will that automatically become a replacement for the old one?---this file is one of many in a book project, all relating to a different project root.  Or is there a way to unlock even when I get that error message?

Howdy,

I this a distributed document; i.e., one that has a root document that \includes or \inputs the other parts? If so, do each of the \included files have a line at the top,

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

that tells TeXShop how to compile the file and also how to sync between the pdf and the proper source file? Note: path/to/root.tex is the absolute or relative path to the root file.

Good Luck,
