Some Type 1 (PostScript) fonts don't appear in the InDesign fonts lists on Mac OS 10.6 and later. For example, when you look at the font Helvetica Neue in the Font submenu of the Type menu, you see Medium Italic, but no Medium. The missing faces do appear under the TrueType version of the font.
Faces listed under Type 1 Helvetica Neue
Install the InDesign CS5 7.0.2 update. This can be found by choosing Help > Updates from any CS5 application, or by downloading from http://www.adobe.com/downloads/updates/.
Put the affected Type 1 font files into the Adobe InDesign application font folder, for example:
- CS3: /Applications/Adobe InDesign CS3/Fonts
- CS4: /Applications/Adobe InDesign CS4/Fonts
- CS5: /Applications/Adobe InDesign CS5/Fonts
InDesign has an order of preference for dealing with font conflicts. For fonts with the same PostScript name (as with Helvetica Neue), the /System/Library/Fonts folder is preferred over the /Library/Fonts folder. Additionally, a preference is made in favor of other fonts when conflicts include a .dfont type font. In earlier versions of Mac OS, /System/Library/Fonts was always populated with .dfont type fonts. Now with other types of fonts included, the preference is to suppress the Type 1 face when it conflicts with the System TrueType version.
