I have updated my TexLive distribution from 2010 to 2011. But when I run pdflatex it still uses the older 2010 version. How can I change this? Also when I use tex --v it only shows the old version: TeX 3.1415926 (TeX Live 2010).

    @Henry Did you install MacTeX 2011 or 'vanilla' TeX Live. On the Mac, MacTeX is usually the best choice. – Joseph Wright Oct 18 '11 at 5:52

    I am not a Mac user, but probably the 2010's pdflatex is higher on the search path. A symlink or something similar should solve the problem. Uninstalling 2010 wouldn't harm too. – pmav99 Oct 18 '11 at 6:33

On the mac, you need to go the menu Apple > Pref System > Distribution TeX and the you can make a choice between TeXlive 2010 or TeXLive 2011.

You can verify your installation : in the finder go to folder (shift apple G) then /usr/local/texlive/ you can see 2010 and 2011.

You verify your Path with in the terminal $echo $PATH.

For me : /usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/X11/bin:/usr/texbin

You can also verify if /usr/texbin is a link through 2011
