Howdy,

TeXShop's latexmk engines read rc files for each particular version of the engines. Those files are located in the ~/Library/TeXShop/bin/tslatexmk folder and should NOT be changed since an update to TeXShop could overwrite them. In addition, after the very first run of any of the latexmk engines there is an editable file, latexmkrcedit, created in the ~/Library/TeXShop/bin folder, which can be edited and will NOT be overwritten. That file is read by all of the latexmk engines. Finally, every project can have a platexmkrc file in the same folder as the project's files. It will be used for the typesetting of any .tex file in that folder using one of the latexmk engines. The order of reading the files is latexmkrcedit, the specific latexmkrc for that engine and finally the platexmkrc file if it exists in the folder containing the typeset document. The order is important because the rc files can overwrite changes made by a previously read rc file.

If you wish you can duplicate one of the engine files and give it a new name, e.g., mylatexmk.engine. Then edit that engine file to read a personal rc file with a special name, e.g., mylatexmkrc, instead of the one named after the ${TSBIN} in the engine. Finally place your rc file, named, e.g. mylatexmkrc, in ~/Library/TeXShop/bin/tslatexmk where it will be called.

Hope this helps.

Good Luck,
