I am running OS 10.10.5 (Yosemite, Mac). After update to TexShop 3.6.1, TexShop no longer works. I understand that this issue would be cured by El Capitain but that is not an option for me.
The last line in my file had local Installer: Displaying 'Install Succeeded' UI. and the word "failed" never appeared in the last 500 lines of the log.
On .tex files that it once worked on, I now get /Library/TeX/texbin/pdflatex does not exist. TeXShop is a front end for TeX, but you also need a TeX distribution. Perhaps such a distribution was not installed or was removed during a system upgrade. If so, go to http://tug.org/mactex and follow the instructions to install MacTeX or BasicTeX.
I tried re-downloading and re-installing TexShop twice, without any change.
In a Terminal window I get no response to “which pdftex”
My current path settings under Engine in TexShop preferences are /Library/TeX/texbin /usr/local/bin
I’d be most grateful for any help you can offer.
