I am a basic user and sorry if I miss to state some important facts.

I have similar problem raised here and also in many other pages. First, I followed the guides by Herbert Schulz, didn't work for me.

Afterwards, completely uninstalled MacTex with all GUI Applications and distribution files, then re-installed MacTex. Still, didn't work.

I also updated TexShop and BibDesk, which are the softwares I use.

Moreover, run the Setup-2015 package at Applications/TeX folder.

However, still when I click to typeset, TexShop brings the following message:

/Library/TeX/texbin/pdflatex/simpdftex 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 (re)install MacTeX. A less likely possibility is that a tool path is incorrectly configured in TeXShop preferences. This can happen if you are using the macports or fink distributions.

This is how my TexShop Preference looks like:TexShop Preferences

  • @daleif It's part of the TeXLive distribution. It does latex+dvips+ps2pdf in one shot.

  • Never heard of it before. Is the OP actually sure it is included in mactex? Can it be found via the comnand line?

  • The problem is that in your Path settings (the first box in your settings image) you have put /Library/TeX/texbin/pdftex but this is incorrect. It should be simply /Library/TeX/texbin

  • @daleif Yes, it's part of TeXLive and therefore part of MacTeX. The issue doesn't have anything to do with this script.

The problem is with how you specified the path in the preferences. The correct path is /Library/TeX/texbin not Library/TeX/texbin/pdflatex (which is not a directory path, but the actual pdflatex program itself. The error you got showed this since it said /Library/TeX/texbin/pdflatex/simpdftex does not exist. The presence of pdflatex in the path is the source of the problem.
