# epstopdf package converts a file, and pdftex package doesn't find it

I'm using texmaker on OSX. After upgrading my OSX to El Capitan, I couldn't do anything in texmaker at first because the .tex file would not be found. I fixed the problem strictly following this guide. Now everything works, except for when I want to include a .eps file in the \includegraphics environment. Then I get the error message:

Here's the relevant part of my code:

\begin{figure}
\centering
\makebox[\textwidth][c]{\includegraphics[width=1.25\textwidth]{figure_overview}}
\caption{Single-parameter sweep overview}
\label{1parsweep}
\end{figure}

The log file says this:

Package epstopdf Info: Source file: <figure_overview.eps>
(epstopdf) date: 2016-02-25 14:04:24
(epstopdf) size: 220121 bytes
(epstopdf) Output file: <figure_overview-eps-converted-to.pdf>
(epstopdf) Command: <repstopdf --outfile=figure_overview-eps-converted-to.pdf figure_overview.eps>
(epstopdf) \includegraphics on input line 85.
runsystem(repstopdf --outfile=figure_overview-eps-converted-to.pdf figure_overview.eps)...executed safely (allowed).
Package epstopdf Info: Result file: <figure_overview-eps-converted-to.pdf>.

(line 85 is the one with the \makebox and \includegraphics command)

So apparently, in contrast to the problem described in
Trouble with epstopdf: File 'foo-eps-converted-to.pdf' not found my epstopdf package seems to work fine but it stores the file somewhere (I don't know where and I have no idea how to find that out), but pdftex is looking for the file somewhere else (I don't know where, either... how can I find that out?). How can I fix this?

If I convert the eps-file to a pdf-file manually and save the respective pdf in the Figures folder, it works. But I want to use .eps files and convert them on the fly, as this gives better results and is easier.

My preamble is:

\usepackage{subfigure}
\usepackage{siunitx}
\usepackage{graphicx}
\usepackage{amsmath}
\usepackage{amssymb}
\usepackage[utf8]{inputenc}
\graphicspath{{./Figures/}}
