To see and install these optional fonts, open the FontBook application and switch to “All Fonts”. Browse the font list and you will see lots of font families that are greyed out—either because they were deactivated or they weren’t downloaded yet. If you right-click on a font or font family that wasn’t downloaded yet, you see an option to download the individual font or entire family.
