Apple has recently licensed fonts from type foundries such as
Commercial Type, Klim Type Foundry and Mark Simonson Studio to be
used as system fonts on Mac OS Catalina. But since these fonts are
an optional download, many users of Mac OS X are not even aware
they have access to them for free.
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.
I can’t believe I didn’t know about this until I saw this post. These fonts are truly excellent, and Apple has licensed them.
