This is the MacOS's Texshop disappearing apostrophe problem.
% !TEX encoding = UTF-8 Unicode
is added to the document preamble.
Within the program:
Preferences=>Source is set to UTF8.
Preferences=>Misc has pTex support unchecked (this solved the problem for many, but not for me.
Under
Edit=>Substitutions none are checked.
I have tried ' and ’ (prime and option-shift-right bracket) but the latter should always yield apostrophes but it doesn't.
MWE:
% !TEX encoding = UTF-8 Unicode
\documentclass[10pt]{scrbook}
\usepackage[english]{babel}
\KOMAoptions{headings=small}
\usepackage{kpfonts}
\usepackage[paperwidth=6in,paperheight=9in]{geometry}
\setcounter{secnumdepth}{0}
\setcounter{tocdepth}{3}
\usepackage[normalem]{ulem} %for strikeout text
\usepackage{mdwlist}
\usepackage{multicol}
\usepackage{makeidx}
\usepackage{idxlayout} %%to fix issues with index

I had this exact problem recently! I tried two things:
\usepackage[utf8]{inputenc}
, with no success. I tried another, related package approach, but had no luck with that, either.I also used XeLaTeX instead of LaTeX, for a related issue. It might be that if I had just used XeLaTeX from the beginning, I wouldn't have needed to manually fix all those apostrophes.
Lastly, the plural of apostrophe is apostrophes, without the apostrophe-s. ;)
