FCPX crashing on every Master export

That is great news. For anybody reading this, be advised you can reset FCPX preferences without a 3rd-party tool. Just launch FCPX while holding CMD+OPT keys: support.apple.com/en-us/HT203477

However a number of people experiencing crash on export when running old versions of FCPX tried reseting preferences and this did not solve their problem. But it's an easy thing to try.

You don't need that app to do that. Simply hold both the Option and Command keys at the same time while launching FCPX.

My FCP started doing this again. Tis time the ‘Preferences’ fix didn’t work!

The most common cause of crashes during export is old plugins or being on an old version of MacOS combined with a certain iTunes update. See this thread for the iTunes issue: www.fcp.co/forum/4-final-cut-pro-x-fcpx/...s-on-export?start=20

Inspect all your plugins and make sure they are updated, especially those from CoreMelt. The CoreMelt installers are here: coremelt.com/pages/downloads
