# 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
../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.
