Since I upgraded my Mac Book to El Capitan, I am not able to use TeXworks.
I changed the path in TeXworks Preference Typesetting to /Library/TeX/texbin.
And then I get the following error.
! LaTeX Error: File `mathexam.sty' not found.
I downloaded mathexam and created mathexam.sty. I placed it in the same directory /Library/TeX/texbin. But it still gives the same error.
Where do I need to place mathexam.sty or sty files in Mac?
