[Jerry Hofmann] “They are located in User/Library/preferences/Final Cut Pro User Data/
There are three red and white icon’d files in that last folder. Just trash them, and give it another go.
“
I’m having the same problem. All of a sudden, FCP won’t fully launch. However, I cannot find the file structure you listed above. In the USER folder, there is only my name (home) and the Shared folder.
If I go the main root disk and then to Library/preferences, there is no folder called Final Cut pro user data.
Any suggestions?
