I'm trying to create a newsletter in inDesign and most of my fonts aren't showing correctly. When I select them they just appear as the default sans serif typeface. I looked in Font Book and all the fonts are installed so I'm not sure what the issue is. (Example below: supposed to be Big Caslon)
UPDATE: All the fonts are appearing under the wrong name
What version and OS do you use? As CS6 and older are not compatible with El Capitan and can cause such problems.
Did you delete program preferences?
Wouldn't hurt to clear your font caches.
