As you can see, I can do it using the Mac keyboard with Mac documents such as this email. I tried inserting it in my LaTeX document but it did not typeset correctly.

Howdy,

How are you typesetting the document? Are you using pdflatex, xelatex, etc?

What font are you using? If you're using pdflatex and Computer Modern try using

\usepackage{lmodern}
\usepackage[T1]{fontenc}
\usepackage{textcomp}

and then you will probably be able to generate the command with the \textonehalf command.

If you are using xelatex (or lualatex) you should be saving in UTF-8 and then, if you are using a font via the fontspec package that contains the character you should be able to just type it in from the keyboard.

In a math equation you should be using the amsmath, or better the mathtools package and then include it by placing the proper thing inside a \text{} command.

Good Luck,
