As I wrote in the title, I'm trying without success to compile the bibliography of my thesis. I'm using the package Biblatex. I know that there are other questions about the same topic, but I couldn't fix my problem.
Here are the packages I'm using.
\documentclass[11pt,a4paper]{book}
\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage[english]{babel}
\usepackage{amsmath, amssymb, amsthm, empheq,braket,mathtools,stmaryrd,graphicx,subfigure,latexsym}
\graphicspath{ {Images/} }
\usepackage{enumitem}
\usepackage{physics}
\usepackage{csquotes}
\usepackage{bookmark} % segnalibri
\usepackage{hyperref}
\usepackage{cleveref}
\usepackage{amscd}
\usepackage[all,cmtip]{xy}
\usepackage{mathrsfs}
\usepackage{booktabs}
\usepackage{caption}
\usepackage{bm} % per formule matematiche in grassetto
\usepackage{esint} %per integrale barrato
\usepackage[style=numeric,defernumbers]{biblatex}
%\usepackage[style=numeric-comp,useprefix,hyperref,backend=bibtex]{biblatex}
\addbibresource{Bibliography.bib}
And the structure of my main.tex file.
\begin{document}
\tableofcontents
\chapter{Chapter One}
\input{Chapters/Introduction}
\chapter{Chapter Two}
\input{Chapters/Ex_and_uniq}
\backmatter
\nocite{*}
\printbibliography
\end{document}
I'm trying to compile before using pdflatex, then using bibtex. What I get while compiling with bibtex is the following error message.
Any help? I'm using TeXworks on a Mac. (Don't know if it's meaningful.)
