I did a test with my windows computer on pandoc,I think the results should be similar for Mac OS. I have two word files created with MS Word 2010. One of them is:
converting it to latex with the following command in windows command window:
pandoc test.docx -s -o test.tex
gives the result:

\begin{itemize}
\item
pwd (or echo \%cd\% on Windows) to see what the current working
directory is.
\item
cd foo to change to the foo subdirectory of your working directory.
\item
cd .. to move up to the parent of the working directory.
\item
mkdir foo to create a subdirectory called foo in the working
directory.
\item
up-arrow to go back through your command history.
\item
tab to complete directories and file names.

run the code in latex and you will get the following pdf
The other word file is a more complex one, It's not exactly converted but it's satisfying. It's not just a copy and paste
I get the following result after converting to latex and then running the latex code. (Because the word file is for an article, I couldn't provide the whole latex code)
actually there are some shortcomings. I'm not asserting that It's perfect. I'm telling it's not just a copy and paste and can be helpful. In my second example I have bibliography in the text that is fully converted. Also tables are converted appropriately but my photos are not converted. For figures I think you should use the other answer. Because the text is one of my unpublished articles, I couldn't provide you the whole code. Indeed you will have some troubles with math formulas. Based on my experiments pandoc is not very good in converting complex lengthy math equations.
my bibliography is created with endnote and fully and perfectly converted
