Howdy,

But can you start a compile from one of your chapter files? With the root set to .../\jobname... TeXshop can't possibly find the proper root file from within the Chapter file. You've always got to compile from one of your root files and those

%!TEX root = ../Chapters-controls/\jobname.tex

are not doing anything.

Good Luck,
