I don't know, if the FontExplorer can support them.
But you should know that PostScript fonts are not supported any more with modern operating systems. They can be used if you put them in the Font folder aside the program.
Yeah, right. Tell that to all the designers that still work with massive postscript font libraries that they've squirreled away with decades in the business. How cavalier is that for Adobe to say buy ALL new fonts. Some of these font families cost hundreds of dollars apiece, especially the classic fonts.
It is not Adobe. Microsoft and Apple are ending Postscript Font (T1) support.
With Adobe applications you can still use them, when you follow how I have described above.
You cannot expect that 20 Years old programs are working without a problem in OS which are developed 20 Years later. No program from that time can do it today. What are you expecting?
I was having the same issue. I just double clicked the fonts to try to open via FontBook and they still opened in FontExplorer. I chose "Remove Font and reimport" and they finally appeared in InDesign. I'm guessing indesign doesn't like fonts that are already added....
or, i got lucky.
I don't know about Font Explorer or Font book (because I never use either of them) but I do use Font Agent Pro (have done so ever since the demise of ATM Deluxe).
FAP has no problem in activating OTF, TT or PS fonts for use in the latest versions of InDesign and includes plug-ins to work with the major Adobe programs.
I am doing a production right now which uses fonts of all three formats and FAP has no problems with activating any of them and making them instantly available in InDesign.
I understand that there was a problem using PS fonts in earlier versions of Mavericks but that seems to have been corrected in Yosemite. And Windows PS fonts could be an issue but I run Macs so don't know if that is true.
