Texmaker not updating the PDF viewer

Question

I created bash file which constantly compiles the my latex file, the problem is though that the PDFviewer in texmaker doesn't update, eventhoug the raw PDF file is updated. How come is does the PDFviewer keep showing the old PDF until i use Texmaker to compile the texmaker?... I want the embedded PDFviewer in texmaker to update, the PDF it shows even though i don't use texmaker to compile the .tex file.

The bash file.

#!/bin/bash
while true
do
    pdflatex -synctex=1 -interaction=nonstopmode /Users/Johnathan/Documents/Bachelor/Rp/bachelor.tex
    sleep 4
done

Answer 1

I know this question is old, but I just had the same problem and found a solution for some Mac Users at least:

The short explanation: since El Capitan, there is no /usr/ directory anymore, but this is where Texmaker looks for latex. In Texmaker -> Preferences -> Commands, substitute every /usr/ expression with /Library/TeX/, which is where Latex is installed.

This document holds all the details. https://tug.org/mactex/UpdatingForElCapitan.pdf
