I just did the disk repair you recommended. I found directions for a complete uninstall of MacKeeper, then did the following (directions from MacKeeper support):
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.
Final Cut is up and running again. I have not checked my other programs, but I feel hopeful. Thanks you. Holly
