iMovie displays a -43 error when exporting or importing files

This article has been archived and is no longer updated by Apple.
When using iMovie 3.0 or later, you may get a -43 error message when you try to do the following:
  • Send an iMovie project to iDVD.
  • Import files into iMovie.
  • Export projects to QuickTime using iMovie's Share feature.
If you come across this error, check to see if you have any third-party plug-ins installed in the following locations:


If so, temporarily disable the plug-in by renaming or removing the iMovie plug-ins folder where the plug-in resides. Then open iMovie again and test to see if the export (or import) succeeds.

For example, older versions of the Slick plug-ins suite may cause this symptom. Gee Three has an update for their Slick plug-ins here. If you have plug-ins from another company, check with the plug-in developer for possible plug-in updates which may resolve this issue.
