Please compile a file containing

```
#(ly:font-config-add-directory
  "/System/Library/PrivateFrameworks/FontServices.framework/Versions/A/Resources/Fonts/")
#(ly:font-config-add-font
  "/System/Library/PrivateFrameworks/FontServices.framework/Versions/A/Resources/Fonts/Subsets/Kaiti.ttc")
#(ly:font-config-display-fonts (current-output-port))
```

Does the returned listing contain your font?  It is possible that the
update on your machine changed the font flavour so that it can no
longer be processed with LilyPond.  If this is the case I recommend to
get the old fonts and install them locally in a directory that can be
found by FontConfig.
