The offical page of Latex is(google says so):
https://www.latex-project.org/
Now I am trying this in MACOS:
http://www.tug.org/mactex/
download the mactex file and install it.
Just immediately after installing mactex you need to start TexLive
Texlive is basically an update manager for latex. It will update your latex verion(which seems like consists of a lot of things)
Now lest see what this texshop is.
##creating your first pdf using latex:
Lets write these in the texshop window:
\documentclass{article}
\begin{document}
hello world!!!!
tlooking great so far
% all kind of comments
\end{document}
Now press Typeset button it might ask first for saving if this is a new file. After that you will see the pdf view :D
