Download and install BasicTeX from tug.org
This is the core part of MacTeX which is too big with 2GB.
Maybe now the space occupied is about 500MB.
On Terminal, install extra packages as follows:
(try latex of pdflatex to find which packages are necessary)
sudo tlmgr update --self
sudo tlmgr install collection-langkorean
sudo tlmgr install bigfoot
sudo tlmgr install manyfoot
tlmgr search --file manyfoot.sty
tlmgr search --global --all manyfoot.sty
sudo tlmgr install ncctools
sudo tlmgr install endnotes
pdflatex filename.tex
(pdflatex and latex are linked to pdftex. But latex does not make pdf, just makes dvi. I don't know why.)
open filename.pdf
