Cannot find pdfLatex after upgrade to Mac OS X 10.11 (El Capitan)

Mine was moved to /Library/TeX/Root/bin/x86_64-darwin/pdflatex, hope that helps!

If you are using homebrew, you'll get this message on the client:

Installing TeX from source is weird and gross, requires a lot of patches, and only builds 32-bit (and thus can't use Homebrew deps on Snow Leopard.)

We recommend using a MacTeX distribution: https://www.tug.org/mactex/

You can install it using Cask:

brew cask install mactex

So that's exactly what I'm doing. Using 'sudo' in front of the command, though, to facilitate installation.

After this, on pre-El Capitan systems, pdflatex would be found in /usr/texbin, however, with El Capitan, installations to /usr are no longer allowed. Hence, you will now find pdflatex and other related binaries in /Library/TeX/texbin. (Many thanks to the R-Bloggers website for this suggestion.) Just add this path to your $PATH env variable.

Yes. Mine moved to /Library/TeX/Root/bin/x86_64-darwin as well. I added this path in my TeXworks Preferences->Typesetting tab under the "Paths for TeX and related programs". Everything seems to be working as usual, though I have not yet checked raw tex and ConTeXt. But I guess things should be fine.
