When you start Adobe InDesign or Adobe InCopy on Mac OS, the application crashes, freezes, or quits with one of the following error messages:
Do one or more of the following solutions:
Solution 1: Delete all Adobefnt10.lst files.
Search for and delete all copies of the AdobeFnt10.lst file that you find on the hard disk:
Solution 2: Troubleshoot fonts by disabling a few at a time.
Solution 3: Remove third-party plug-ins from the Plug-ins folder.
Identify third-party plug-ins and then remove the plug-in files for each of those plug-ins.
To identify third-party plug-ins in CS4 and earlier, choose choose Help > Configure Plug-ins (Windows) or InDesign > Configure Plug-ins (Mac OS).
To identify third-party plug-ins/extensions in CS5 and later, choose Help > Manage Extensions (Windows) or InDesign > Manage Extensions (Mac OS).
To remove third-party plug-ins: Move the plug-in file for each plug-in from the Adobe InDesign [version]/Plug-ins folder to a backup folder and restart InDesign/InCopy.
If you identify problems with third-party plug-ins, then please complete a bug report, available on the Adobe website at www.adobe.com/misc/bugreport.html. Be sure to include the plug-in name, version and manufacturer.
Solution 4: Disable the Font Agent plug-in.
If you've installed Extensis Suitcase on the system, disable the FontAgent plug-in that comes with the application. You may also want to check the Extensis website (www.extensis.com) for updates to Suitcase.
Solution 5: Start the application in Safe mode and disable Font Preview.
If an Adobefnt10.lst file becomes damaged, it can cause InDesign or InCopy to crash, freeze, or quit when you try to start it. Adobefnt.lst files (for example, Adobefnt10.list) are font cache files that Adobe applications use to quickly gather and store information about available fonts. If you delete or rename an Adobefnt.lst file, the application will re-create it the next time you start the application.
