Fontspec can't find italic font (installed later) but will use condensed (installed first) on OSX

Question

I installed a bunch of Myriad Pro variants in Font Book and was using LuaLateX to set the section headers to this font:

\newfontfamily{\headingfont}{Myriad Pro}
\renewcommand{\maketitlehooka}{\LARGE\headingfont}
\titleformat{\chapter}[display]
{\headingfont\huge\bfseries}{\chaptertitlename\ \thechapter}{0pt}{\Huge}
\titlespacing*{\chapter}
{0pt}{0pt}{30pt}
\titleformat*{\section}{\normalfont\LARGE\headingfont}
\titleformat*{\subsection}{\itshape\Large\headingfont}
\titleformat*{\subsubsection}{\normalsize\headingfont}

However I noticed it was using the condensed italic for the italic font.

I then noticed I didn't have the regular italic font installed. So I installed it, but no change.

Removing the condensed italic I then got an error that the italic font could not be found. What is going on?

This is the output of fc-list (when the condensed fonts were installed)

./fc-list | grep "Myriad"

Updating lualatex font information as @cfr said fixed it.

1. Open terminal and change to you texlive bin directory:

   cd /usr/local/texlive/2014/bin/x86_64-darwin

2. Run the font update

   luaotfload-tool -u
