Resolve an issue in Final Cut Pro X

Learn how to isolate, troubleshoot, and fix issues in Final Cut Pro X. 

Follow the recommendations below in the order in which they’re listed until you've isolated or fixed your issue. Before proceeding, make sure to back up your Final Cut Pro X libraries, media, and the Final Cut Pro X application.

1. Restart your Mac

Restarting your computer resets Final Cut Pro X-related system resources. To restart your Mac, choose Apple menu () > Restart, then reopen Final Cut Pro X and try to reproduce your issue.

2. Disconnect external devices

An incompatible or malfunctioning external device can sometimes cause issues with Final Cut Pro X. To test external devices:

  1. Shut down your Mac.
  2. Disconnect all external devices other than your keyboard and mouse.
  3. Reset NVRAM. You only need to do this the first time you disconnect external devices.
  4. Open Final Cut Pro and attempt to reproduce your issue. If your issue no longer occurs, reconnect devices one at a time until you can reproduce your issue. Make sure to restart your Mac after reconnecting a device, if the device requires it. 

If the issue only occurs with a certain device connected, you might need to update or service the device. Contact the manufacturer for support.

3. Check Final Cut Pro X documentation

Check Final Cut Pro X Help to make sure Final Cut Pro is working as expected. You can search Final Cut Pro X Help for key terms shown in alerts, alert icons, or error messages.

4. Check system requirements

Make sure your Mac meets Final Cut Pro X system requirements.

5. Make sure Final Cut Pro X is up to date.

Before updating Final Cut Pro, back up your existing libraries and your current copy of the Final Cut Pro application. This allows you return to the previous state your files and the application were in if updating does not address the issue.

To make sure you're using the latest version of Final Cut Pro X, choose Apple menu () > App Store, then click Updates in the toolbar. If a Final Cut Pro update is available, you can click the Update button to download and install it.

6. Verify installation of Pro Video Formats

Make sure you've installed Pro Video Formats.

7. Check media and device compatibility

Make sure you’re using a compatible media format, device, and external storage device format. Contact the manufacturer of the device(s) for support. If a software update for the device is available, follow the manufacturer's instructions to update firmware for devices like cameras and external storage devices, or to update drivers for devices like interfaces.

8. Check software compatibility

If you're using a plug-in or other software not made by Apple with Final Cut Pro, make sure it's compatible with your version of Final Cut Pro. Contact the manufacturer for support. If an update is available, follow the manufacturer's instructions to update the software. 

9. Try using another user account

Open Final Cut Pro X in another user account on your Mac. Logging in as another user can help you figure out if unexpected behavior is related to a specific user's settings or files.

10. Test with a new library and project

Create a new library and project, and try to reproduce the issue using known-good media—media you've used successfully in other projects. If you can't reproduce the issue using known-good media, the issue might be related to the media in the affected project. Obtain new copies of the media from the original source.

If you don’t have known-good media available, you can create some using a placeholder and a sound effect from Final Cut Pro X Additional Content, which you can then share to an Apple ProRes 422 Master File. Import the Apple ProRes 422 Master File into a new library and project and try to reproduce the issue.

You can also try to reproduce the issue using media from the affected project in the new project. If you can't reproduce the issue, you can try resetting Final Cut Pro preferences.

11. Reset Final Cut Pro X preferences

Resetting preferences doesn't affect your libraries, projects, or media. However, any custom preference settings will be reset to their default settings.

Before resetting preferences, choose Final Cut Pro > Preferences and note any specific settings you've made. That way, after resetting preferences, you can go back and reapply your custom settings. For information on different preferences, see the Final Cut Pro preferences overview in Final Cut Pro Help.

To reset preferences in Final Cut Pro X 10.3 or later:

  1. Quit Final Cut Pro.
  2. Hold down the Command and Option keys, then open Final Cut Pro.
  3. Click Delete Preferences.
  4. Try to reproduce the issue you were experiencing. If the issue no longer occurs, open Final Cut Pro preferences and reapply your custom settings.

12. Remove and reinstall Final Cut Pro X

To remove and reinstall Final Cut Pro:

  1. In the Finder, choose Go > Applications.
  2. Locate Final Cut Pro and drag it to the Trash.
  3. Reinstall Final Cut Pro X from the App Store, or restore it from a backup. When restoring a copy of the Final Cut Pro application from a backup, you can either drag it from its storage location to your Applications folder or restore Final Cut Pro from Time Machine backups.
