I'm having major issues with FCPX. Yesterday it started crashing every time I opened it up. Today is the same. I finally got it working yesterday after Chris Fenwick talked me through a UNIX startup, as soon as I close FCPX and try top open it again the problem is back. Have completely reset my MacBook, I now have zero plugins in the app... If anyone has any idea what I can try to resolve this id be really grateful. Thanks.
