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!
