Hi
I had the same problem today just after I used the application called “Clean My Mac”. So I guessed it was related to some frameworks’ folder. I solve it this way:
1. Control click the Motion App and choose Show Package Contents from the contextual menu.
2. Go to the Frameworks/Ozone.framework/ folder.
3. Delete the file called “Ozone”.
4. Go to the Frameworks/Ozone.framework/Versions/A/ folder. Pressing Alt and Command keys together than click and drag the file “Ozone” to the “Frameworks/Ozone.framework/” folder, creating an alias from the original Ozone file.
5. Open the Final Cut and I hope it works to you.
All the best!
