# Checking MacTeX version installed on a Mac

I can use `latex -v` to check the version of LaTeX. Is there a way to check what version of MacTeX (MacTeX 2008, 2009 or 2010) is installed?

MacTeX installs a System Preferences pane which shows TeX installations for selection. There you can see the version.

Here's a screenshot:

Oh. I thought he wanted something that he could check programmatically. –  Harald Hanche-Olsen Dec 17 '10 at 17:34
This is the right (i.e., Mac-like) answer. I totally forgot about the preference pane. –  Matthew Leingang Dec 17 '10 at 17:55
``````; readlink /usr/texbin
../usr/local/texlive/2010/bin/x86_64-darwin
``````

Weird. On my mac that gives `../Library/TeX/Distributions/.DefaultTeX/Contents/Programs/i386` But `readlink /usr/textbin/` (note the trailing slash) gives `../../../../../../../usr/local/texlive/2010/bin/x86_64-darwin` –  Matthew Leingang Dec 17 '10 at 16:43
Yeah, `/Library/TeX/Distributions/` contains a whole mess of links. I have no idea why my `/usr/texbin` is a direct link rather than indirecting though said mess. –  Harald Hanche-Olsen Dec 17 '10 at 17:41
Your programmatical approach is fine. I like the command line. –  Stefan Kottwitz Dec 17 '10 at 17:45
``````cd /usr/texbin
pwd -P
``````

This gives me `/usr/local/texlive/2009/bin/universal-darwin`.

Create a "hello world" latex file and compile it. Look at the console or `.log` file and see what files are being loaded. On my machine I see

`(/usr/local/texlive/2010/texmf-dist/tex/latex/base/article.cls...`

So you can guess it's TL 2010.
