iMovie error 2191

Hi, Sunnydays,

I do not recognize error code -2191. It doesn't show up in Terminal and I don't see it listed, though it might be on some list that I don't have. In the Windows PC system it refers to a system file error in the registry. I have not seen any info about error 2191 regarding a Mac.

If you are using iMovie 11 that old version has become increasingly less functional with operating systems from El Capitan forward. That might be the cause of the problem. If that's the case, the solution would be to upgrade to iMovie 10.1.9 (current version). From within iMovie 10 you can update your projects and events from iMovie '11 (version 8).

iMovie 10 has a very different structure and user interface that iMovie 8. So there will be a bit of a learning curve.

Here are some diagnostics you can try or consider:

1. For iMovie 10, open iMovie while holding down the Option and Command keys and selecting to delete preferences in the box that appears. iMovie will open in a new library. Reopen your old library to get back to your projects. Now see if you can export.

2. In your project, do an Edit/Select All, Edit/Copy, and paste your project media into a newly created project and try to share out.

3. Open iMovie in a new user account. The Guest account on your Mac will suffice for this purpose.

4. You might try booting up in Safe Mode (see Help menu) and, after everything has loaded, immediately shut down and reboot in normal mode. See if iMovie works properly.

5. Often export problems occur because of corruption in the project media. Try scrolling slowly through your project, looking for white flashes, black frames, artifacts and other signs of corruption. If you find anything, cut it out of the project and try to export again.

6. Make sure that you have enough space on your boot drive for iMovie to function and enough space on your destination drive to receive the movie. 20GB to 25GB is often recommended.

7. Do a first aid repair, using the Disk Utility app on your Mac. It is found in the Disk Utilities folder located in the Applications folder.

8. Update iMovie and your operating system to current versions. That would be iMovie 10.1.9 and Mojave.

Good luck with this.
