Reinstalling QuickTime

Printer-friendly version

Another possible culprit of your Final Cut Pro problems could be an issue with QuickTime, which is a major component to the workings of Final Cut Pro. One problem could stem from a bad installation (update) of QuickTime. Another reason to re-install QuickTime is if the current version is not compatible with the version of Final Cut Pro you are running and if you need to install an earlier version of QuickTime. The instructions next cover both scenarios.

1. Before installing the same (or older) version of QuickTime on your computer, you will want to delete certain receipt files first. This Apple article covers which files to delete: http://docs.info.apple.com/article.html?artnum=301852

2. Then navigate to your user Home directory > Library > Preferences.

3. Delete these QuickTime preference files:

com.apple.quicktime.plugin.preferences.plist
com.apple.quicktimeplayer.plist
QuickTime Preferences

4. Repair permissions on your main hard drive.

5. Install QuickTime from Software Update or by downloading it from http://www.apple.com/quicktime/mac.html . For an older version of QuickTime, go to http://www.apple.com/support/ and do a search for the particular version you are looking for.

6. After the install and subsequent computer restart, repair permissions again.
