# [Tex/LaTex] How to install TikZ for LaTeX

tikz-pgf

I need urgent help to install hf-tikz on my Mac. It used to work before I upgrade to OS X 10.9 but it doesn't work now. The error message is

 LaTeX Error: File hf-tikz.sty' not found.


I have download and put hf-tikz.sty in the directory that I think it is the right path but it still gives me the same error. I have a presentation tomorrow! :(`
