# Using PGF/TikZ 3.0 on mac

Today I updated my MacTeX/texlive distribution and I have finally PGF/TikZ version 3.0.0!! However, after using the 2.10-CVS version as described in this answer for a long while, I want to make sure that I know how to revert to the global installation so I could use the newer version. I guess I have to delete the relevant directories as described in the answer. And then what? Is it enough?

If you installed the CVS version in your local directory you don't need to do anything other than removing it. Did you overwrite version 2.10 ? – percusse Mar 2 '14 at 10:23
@percusse: I installed the CVS in my home and didn't overwrite the shipped version. Now I have in my home 2.10-CVS and in the global one 3.0.0. Remove the things in home is enough? Shouldn't I refresh the database somehow (texhash)? – Dror Mar 2 '14 at 10:33
@Dror: yes, removing it will be enough. – Franck Pastor Mar 2 '14 at 14:38
+1 for the implicit announcement that version 3.0 is finally on CTAN. – Charles Staats Mar 2 '14 at 14:41
@fpast: I did it, and it seems to work. One issue: I don't have access to the documentation through `texdoc`. In particular, `texdoc tikz` returns: `The file /Users/username/Library/texmf/doc/generic/pgf/pgfmanual.pdf does not exist.` How can I fix it? – Dror Mar 2 '14 at 20:24

Here is how I proceed to use PGF 2.1 cvs or PGF 3.0 and my personal packages with OS X 10.9 and TeX Live 2013.

pgf and my packages are in `/usr/local/texlive` ... I created a `texmf` folder in `~/library` and then I placed the different PGF folders in `~/library/texmf/tex`. If I update my packages I place them in `~/library/texmf/tex/latex`.

Normally, with a standard distribution, TeX searches firstly inside `~/library/texmf` and then in the others paths.

If you want to stop to use PGF 3.0 it's enough to zip the different PGF folders and to place the PGF 3.0 folders in the trash.

Now with the last TeX Live, you have nothing to do (no `texhash`, etc.).

Another possibility is to place PGF 3.0 or a special package inside a folder with the document that you want to compile. In this case the files inside this folder are used.

Remark: If you want to use again PGF 3.0, the only thing to is to expand the zip files.

Currently in `/usr/local/texlive/...` I have 3.0 and in `~/Library/texmf/...` I have 2.10-CVS. Basically you say I shouldn't do anything? It doesn't seem to hold, for instance `texdoc tikz` loads the documentation of 2.10-CVS. – Dror Mar 2 '14 at 20:16
For texdoc I think it's normal. In txmf.cnf you can read : % TeX documentation and source files, for use with texdoc and kpsewhich. TEXDOCS = \$TEXMF/doc// I don't know if it's possible to find the doc pgf 3 before pgf 2.1 without changing the variable \$TEXMF. Personally I used often the pgf manual also I use the dock to open the file. It's also possible to use an alias. – Alain Matthes Mar 2 '14 at 20:31
@Dror it's not pgf 2.1 in `/usr/local/texlive/...`and pgf 3 in `~/Library/texmf/...` ? – Alain Matthes Mar 2 '14 at 20:34
No :) I have just upgraded the `texlive` and now `3.0` is in `/usr/local/texlive`. – Dror Mar 2 '14 at 20:38
Where can I find this `texmf.cnf`? – Dror Mar 2 '14 at 20:38
