Keynote shows missing fonts -- Mojava vs. High Sierra problem
I have created a couple of Keynotes presentations on a machine running High Sierra. When I open this keynote on a machine running Mojave, Keynote complains about missing fonts. However all these fonts are actually installed.
Some of these fonts are standard fonts (like Courier, Helvetica, Monaco), and some fonts were installed manually (e.g. https://fonts.google.com/specimen/Martel). So even if the operating system would install slightly different versions of the fonts, at least the manually installed ones should be really identically.
On the Mojava machine, I "replaced" these fonts with, well, themselves. Then it worked. Saving and opening the presentation again works fine. BUT: Now I see the same weird warning on the machine running High Sierra.
It looks as if Keynote "interprets" fonts differently on High Sierra and Mojava.
Notes:
- both machines use Keynote version 9.0.
- I already tried "validating" the fonts without success
Anyone any ideas?
