If you are not able to save a PDF on Final Draft on a Mac, the Final Draft system preferences may need to be reset. This will not affect your files, but it may affect any toolbar customizations you have performed.
To reset the Final Draft system preferences:
- Quit Final Draft;
- Go to Applications > Utilities > Terminal;
- Type defaults delete com.finaldraft.finaldraft.v13 / v12 / v11 (ONLY enter the version you have)
- Press Return on the keyboard;
- Quit Terminal.
- Reopen Final Draft.
You should now be able to create a PDF without issue.
