Recently Apple has 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 they are an optional download, so you may not be aware you have access to them for free.

To install these 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.
