# How do I install this TikZ/PGF package?

I'm having difficult in figuring out how to install TikZ package in my mac (i just need to draw some diagrams under the enviroment {tikzpicture}), the file that I downloaded (http://sourceforge.net/projects/pgf/) is not just a .sty file. In fact, there is a lot of files inside the folder. Furthermore, I have only installed MacTeX.

Sorry if the question is trivial and thanks in advance.

• TikZ is installed as part of MacTeX as standard: have you tried to use it before messing about with extra downloads? – Joseph Wright Dec 31 '13 at 10:38
• @JosephWright Yes, but apparently it's not installed. – user1286390 Dec 31 '13 at 10:39
• Did you do a full MacTeX install? If so and if TikZ is missing then something has gone wrong with the installation. What exactly did you try to see if it's installed? – Joseph Wright Dec 31 '13 at 10:40
• @JosephWright Yes and I tried to include the package tikz but it does not identify it when compiling. – user1286390 Dec 31 '13 at 10:44
• If \listfiles\documentclass{article}\usepackage{tikz}\begin{document}\end{document} doesn't work then you've got a defective installation. I'd be tempted to remove it and try again: there are probably other issues lurking. – Joseph Wright Dec 31 '13 at 10:48
