So I installed the new OSX update, Mavericks. Hadn't noticed anything weird in its running, except that when I went to run Photoshop my most commonly used font, Lucida Handwriting Italics was missing. It's still in my font book on my Mac, so that's not the issue, but it's like Photoshop just doesn't recognize it. I tried dowloading another copy, but my font book said that I had duplicates and I had to disable the newly downloaded one. I need this particular font for my job. Any ideas?
I have upgraded to Mavericks and the Lucida Handwriting Italic font is there and working in both CC and CS6.
Here's a font troubleshooting guide that should help you find and fix your font problems.
All I can tell you is that Lucida should be there, what I can't tell you is what exactly to clear or reset.
