FCPX and Compressor doesn't start. They show crash on loading. On the other user on the same system, I can run FCPX without problems. I tried to reset preferences (alt+cmd then click on app). Tried to uninstall it different ways. But when I install it again I get the same crash. I tried apple method: And nothing helps. How to completely uninstall it and make fresh install (to see these moving icons at first start etc.)?
