After installing Mac OS 9, you may need to be identified as a QuickTime Pro user again. To establish your QuickTime Pro registration again, you can:
- Re-enter the name and registration number into the QuickTime Settings control panel.
- Recover the old QuickTime Pro settings, if a clean installation was performed, by copying the QuickTime Preferences file from the Previous System Folder to the new System Folder using the following steps:
1. Open the Preferences folder of your current System Folder and move the QuickTime Preferences file to the Trash.
2. Open the Preferences folder of your previous System Folder and drop the QuickTime Preferences file onto the new System Folder. It will be automatically moved to the Preferences folder.
3. Restart the computer and empty the Trash.
