[Tex/LaTex] TeXworks stopped creating pdf’s

Question

I just installed TeXworks on my MacBook pro and I created a simple .tex file. It worked just fine and created the PDF any time I ran 'pdfLaTeX'.

Now that I've created a new file it doesn't create the PDF any more.

My MWE is

\documentclass{article}
\title{ \textbf{Interação e Concorrência} }
\author{Limiano}

\begin{document}

\end{document}

Answer 1

Your document produces no PDF output because the actual document has no content. Although you've defined a title and author, this information is not added to the document until you use \maketitle.
