If Final Cut Pro isn’t working
Find out what to do if Final Cut Pro for Mac won’t open, won’t play a project or isn’t operating as expected in other ways.
Before proceeding, make sure you back up your Final Cut Pro libraries, media and the Final Cut Pro application.
Try these steps in order
After trying each step in this list, test Final Cut Pro again to see if you’ve fixed your issue.
Restart your Mac
Choose Restart from the Apple menu .
Disconnect external devices
An incompatible or malfunctioning external device can sometimes cause issues with Final Cut Pro. To test external devices:
Quit Final Cut Pro, then choose Shut Down from Apple menu .
Disconnect all external devices other than the keyboard and mouse.
For Intel-based Mac computers only, reset NVRAM. You only need to do this the first time you disconnect external devices.
Turn on your Mac.
If the issue only occurs when a particular device is connected, you may need to update or service the device. Contact the manufacturer for support.
Check system requirements
Make sure your Mac meets Final Cut Pro system requirements.
Make sure the app is working as expected
Update Final Cut Pro
Try to complete all active projects.
If you haven’t already, back up your existing libraries and your current copy of the Final Cut Pro application.
Choose Apple menu > App Store, then click Updates in the toolbar. If a Final Cut Pro update is available, click the Update button to download and install it.
Verify installation of Pro Video Formats
Make sure you’ve installed Pro Video Formats.
Check media and device compatibility
Make sure you set the Privacy & Security settings on your Mac, which gives Final Cut Pro access to your photo library, Microphone, Camera, and Files and Folders.
Don’t try to store Final Cut Pro libraries in these locations:
On a storage device you’re using for Time Machine backups.
On the Desktop or in the Documents folder with Desktop & Documents turned on in iCloud Settings.
With third-party cloud storage services.
Check that you’re using a supported media format.
For any external devices you’re using, such as cameras, storage devices or interfaces, check with the manufacturer for software or firmware updates. Follow the manufacturer’s instructions when updating.
Check third-party 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 and your version of macOS. Contact the manufacturer for support. If an update is available, follow the manufacturer's instructions to update the software.
Test in a new user account
Create another administrator user account on your Mac, then try to recreate the issue in the new account. If the issue doesn’t occur in the new account, settings or files in the original account may be causing the issue.
Test with a new library and project
Create a new library
In the new library, create a new project using test media.
Try to reproduce your issue.
If you can’t reproduce the issue using test media, the issue may be related to the media in the affected project. Obtain new copies of the media from the original source.
Reset Final Cut Pro preferences
Resetting preferences doesn't affect your libraries, projects or media. However, any custom preference settings will be reset to their default settings. To reset Final Cut Pro settings:
Choose Final Cut Pro > Settings and note any specific settings you’ve made.
Quit Final Cut Pro.
Hold down the Command and Option keys, then open Final Cut Pro.
Click Delete Preferences.
Try to reproduce the issue you were experiencing. If the issue no longer occurs, open Final Cut Pro settings and reapply your custom settings.
Remove and reinstall Final Cut Pro
To remove and reinstall Final Cut Pro:
In the Finder, choose Go > Applications.
Locate Final Cut Pro and drag it to the Bin.
Reinstall Final Cut Pro 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.
Test with a new volume
These steps are a final check to make sure Final Cut Pro, macOS and your Mac are working as expected by isolating to only Apple software and hardware, setting aside your libraries and projects, media and all other third-party items, such as plug-ins.
Install macOS on a new volume of your built-in startup disk. Make sure it’s the same version of macOS you’re currently using.
When macOS installation has completed, set up the Mac, then set the default startup disk to the new test volume.
Shut down your Mac and disconnect all devices, except for a keyboard and mouse or trackpad.
Turn on your Mac.
Select the primary volume in the Finder, then press Command-E to unmount the primary volume. This will leave only the test volume mounted.
Download and install Final Cut Pro from the Mac App Store.
Use the test media to try to recreate the issue.
If the issue doesn’t occur, this will confirm that Final Cut Pro, macOS and your Mac are working as expected.
