# pdflatex with TEXshop on macOS does not the same as Terminal “pdflatex filename” [duplicate]

My TEXshop gives me a error because of the known problem "can not determine size of graphic in filename.jpg" (no bounding box)

So i tried several atempts to solve it.

One was this Cannot determine size of graphic by setting the natwidth and so on.

Because nothing helped and out of curiosity i opened macOS terminal an executed this line: pdflatex "filename" and that runns through without a error.

So i tried to understand the settings in TEXshop by defining the path (pdf)Tex to what i get when searching for the path in terminal with `which pdflatex` as i read here: https://tex.stackexchange.com/a/237764/118709 in my case it spits out:

`/Library/TeX/texbin/pdflatex` in terminal.

But copy pasteing this line does not work as described in the post. When i click "setzen" in TEXshop with the dropdown set to LaTeX.

Althrough the path is the same until the part of /pdflatex so i assumed that pdflatex is the file itself and not the path. Especially because beneth of that path i have a line to set the Tex and Latex Variables and there i have this in the Latex line:

`pdflatex --file-line-error --synctex=1`

So i have no idea how to get the same result as if i use pdflatex in Terminal with TEXshop..

Does anybody have a clue?

And how is the line TEX+divips+distiller related to the result?

I found the solution to this problem my self. the document title:

``````%!TEX TS-program = LaTeX
%!TEX encoding = UTF-8 Unicode
``````

gets read by the program! it seams like the % symbol here is not recognized as a comment. Instead it sets the environment to compile the document as you like.

``````%!TEX TS-program = pdfLaTeX
%!TEX encoding = UTF-8 Unicode
``````

Helps to define the compilation as pdflatex but also prevents the settings in the tool you use. well for shure in TEXshop on mac...

Hope that helps somebody in future...

• it is a comment to tex but it is a texshop-specific comment which your editor "TS-program" uses to have document-specific settings. – David Carlisle Dec 19 '16 at 8:26
