Tired of El Capitan Font Issues

I've boiled it down to mostly Postscript 1 fonts incompatibility with Quark under El Capitan.

I noted this earlier in this topic. This is a known issue with El Capitan.

1) If you put legacy Mac TrueType or Type 1 PostScript fonts in the root Library's Fonts folder, they may or may not show up in any, or all apps. You also may only see part of set.

2) If you open legacy Mac TrueType or Type 1 PostScript fonts in any font manager "in place", the same thing will happen.

3) If you put legacy Mac TrueType or Type 1 PostScript fonts into the Fonts folder of your user account, they will work as expected in all apps.

This bug does not affect OpenType fonts. I haven't yet tested to see if this has been fixed in 10.11.3.

I don't know if you've read this Suitcase Fusion support page but if not, here it is…

I have had to grapple with the same issue for a while, but only because I started removing fonts from the System > Library > Fonts and the Library > Fonts folders. I even had Axure Pro crash on opening files because of missing fonts. I decided to spend some time testing which fonts are causing the issues if missing (removed). I did a "restore" of OSX by restarting a test drive and using "Command+R" to go into restore/ utilities, terminal mode at startup. 30 min of restoring later all the fonts came back. OSX El Capitan installs over 1 GB of fonts between the System > Library > Fonts and the Library > Fonts folders ⚠.

I started removing some fonts from both folders just for the sake of it and test the system. I could usually test quickly between iMessage and emojis in messages if a required font was missing. I also looked at other apps and font displays. I managed to cut fonts down in these two folders to about half of what OSX installs by default.

Hopefully this will help. Here's a list of fonts I have between the System > Library > Fonts and the Library > Fonts folders and everything on my Mac is hunky dory (I'm not saying these are all required, I'm sure I could cut the list down more but I haven't had time to play with it more):

I had the same issue. I rebooted in Safe Mode, it fixed the corrupted font cache, and I restarted it again and the font issue was fixed.
