  2. Select All Fonts.

Isolate the problematic font on macOS

Keep only one version of each font in one of these folders:

  • /Users/[user name]/Library/Fonts
  • /Library/Fonts
  1. Create two folders on your desktop named "fonttest" and "goodfonts".
  2. Move half your fonts from a Library/Fonts folder to the fonttest folder.
  3. Test Photoshop for the original problem.
  4. If the problem persists, move fonttest folder contents to goodfonts, then move half the remaining fonts from Library/Fonts to fonttest and test again.
  5. If the problem disappears, move Library/Fonts contents to goodfonts, then move half the fonttest fonts back to Library/Fonts.
  6. Continue dividing and testing until you identify the problematic font.
  7. Remove the damaged font and restore all good fonts to the original location.
