From your screen capture, it's clear that Adobe Acrobat definitely doesn't recognize your existing fonts. That's what the odd-looking bullets mean.
Font issues are rampant with the latest version of Apple OS High Sierra. Some programs recognize the old location of the fonts, others don't.
Also, High Sierra doesn't handle PostScript fonts, so check that your version of LinotypeProjekt-Regular is an OpenType font (or TrueType).
RE: LinotypeProjekt — is it a traditional desktop font or is it licensed through Linotype's font program or Adobe's TypeKit? The "rent a font" programs like TypeKit can wreak havoc when programs don't recognize the font. With traditional desktop fonts (download the OTF/TTF file and install it), you have more control over where they are installed.
One solution that has worked for some users:
- Uninstall the font.
- Reboot your computer (clears out any fonts that are cached).
- Reinstall the fonts. Use Apple's FontBook app or another font manager like Linotype's Font Explorer Pro.
- Launch Acrobat and the form file and see if they fonts return.
Here are some other forum posts and independent blogs about similar problem with fonts, albeit with other programs, but the theory is the same throughout your computer. Fonts are controlled by the operating system.
Some folks have found that it makes a difference where the fonts are stored, as you'll read in the above posts.
Let us know if any of these solutions work for you.
