## Problem Statement

Opening a valid .tex file using TeXShop to generate a pdf file resulted in the following error and suggested that the mactex installation was either missing or corrupt

/usr/texbin/pdflatex does not exist

Resolution

Instead of re-installing, the problem was fixed by changing the default configured pdftex engine path setting in TeXShop. (TeXShop > Preferences > Engine > Path)

Obtain correct bath by running the following command on the terminal

$ which pdftex
/Library/TeX/texbin/pdftex
