Hi Jenny and Allan,
Btw: Ideally we would have the above be unnecessary, but I assume that due to the new security restrictions in 10.11 (rootless) MacTex moved its binaries to /Library/TeX/texbin and we have not yet updated the LaTeX bundle to also check this location for a possible tex install.
“Typeset & View (PDF)” already assumes that `kpsewhich` is located at `/Library/TeX/texbin/kpsewhich`[1]. There is need to extend `PATH` just to use said command. For example, the `PATH` variable on my machine does not include the location of the TeX binaries.

A few of the other commands in the LaTeX bundle – e.g. “Open Included Item” – might not work correctly, if you do not extend `PATH` the way Allan described. I plan on fixing the remaining commands in the future. For example: “Open Included Item” already works without extending PATH in the version of the LaTeX bundle on my computer.
Kind regards, René
