I'm finally on the way of having an acceptable/workable latx setup on macOS.
TLDR: vim + zarathura-pdf-mupdf --with-synctex downloaded with brew.
There's not much to say anymore except: look at this link. I suppose that vimtex will even boost the working environment more and autocompile in the background with every save? That would at least be the dream. But more on this topic will come next time. I should be writing 500 words for my thesis now. But somehow I broke the blog by writing this blog post with spaces in the title or by the last commits I did? :-$
the spaced title definitively breaks the navigation section :-P
