I run into this problem after I upgraded my mac system:
Error : could not start the command : "/usr/texbin/pdflatex" -synctex=1 -interaction=nonstopmode
My mac is Mojave (Version 10.14.4), Texmaker version is 5.0.3
Does anyone have the same problem? How to solve it? Thanks!
whichorlocateto check the exact location of pdfLaTeX then add that folder to the places where apps are to be found although a diferent set-up the principle is universal so this may give hints https://tex.stackexchange.com/questions/393593/mactex-problem-pdflatex-does-not-exist-error/457416#457416 – May 14 '19 at 03:27
