Apple has added some additional fonts in the latest 10.15.5 version of macOS Catalina. I have a bunch of fonts, but it does not hurt to add a few more, they might come in handy. The fonts are not added automatically when you upgrade to 10.15.5, you have to activate the ones you want manually using the Font Book App. Here is how you do that.
Locate the Font Book App in your “Applications Folder” and boot it up:
Click on “All Fonts”, then you can scroll through the fonts in the adjacent column. When you select a font, you can preview it in the window.
Look at the “Domaine Display” font in the list. It is grayed out. You can click on it and it will display in the far right column”
If you like how this font looks, you can click on the “Download” button. When you do that, you will receive this message:
Just click on “Download” again and the font is installed. As you continue down the list you will see more grayed out fonts. You can preview and install the ones you like.
Even if you have plenty of fonts on your system, it cannot hurt to preview and add a few more. It is cool that Apple has included these extra fonts in macOS Catalina.
