This issue may be resolved by removing the font database. To do this:
Important: If you use Font Book to manage your fonts, you will need to open Font Book after step 3. Font Book library information will be restored. However, the state of whether fonts are active or disabled will be lost. You will need to correct this manually.
- Shut down your computer.
- Start up your computer while holding down the Shift key. This starts your computer in Safe Mode and removes the font database.
- Restart your computer.
- Open the application that quit unexpectedly (iWeb, Keynote, Pages, or Numbers).
