I need to know what packages are used in a LaTeX file. Is there a way to list them? For example, I have a file which uses tikz-dependency, how can I find out which packages this package uses?
If there's a fancy OS X way to do it, that's welcome. I have MacTex installed, but I didn't manage to find a tool which does this. (Tex Live Utility lists packages, but not dependencies.)
On any system you can add the command \listfiles to your document and near the end of the log you will then find a list of files used in that computation. For example,
\listfiles
\documentclass{article}
\usepackage{tikz}
\begin{document}
\begin{tikzpicture}
\draw (0,0) -- (1,0) node[rectangle,draw,right] {X};
\end{tikzpicture}
\end{document}
writes the following in the log file:

***********
Note this command only detects files loaded via standard latex file macros, including \documentclass, \usepcakage, \include. It also works for \input if used in the LaTeX way \input{file}, but not if used in the plain tex way \input file. It does not list .aux files, nor the .toc as input by \tableofcontents. There is an internal LaTeX command \@input that can load files without placing them on this list.
I am investigating a problem on Linux where I am interested in tracing the full pathnames of resources loaded by my LaTeX processors. My answer is to run under strace -e trace=open. The equivalent on macOS is dtruss, I believe.
