Keynote will not display some fonts
Fonts installed and validated on Font Book are not available on the iWork applications such as Keynote or Pages.
Other system software such as TextEdit and third party ones including Creative Cloud have no issues using these fonts. It seems to be an iWork isolated problem limiting creative usage of the bundle.
All software up to date as of writing. One of the example fonts I have issues with is called Freehand. Available open source on Google Fonts.
I'll be looking forward to a resolution.
