If you've ever used an earlier version of iMovie, when you first open iMovie (version 10.0 or later), you’re asked to update your existing iMovie projects and events.
After you update your projects and events, copies of the original iMovie Projects and iMovie Events folders are left in place. The files in these folders can still be opened by previous versions of iMovie. If you don't want to use these files in the future, delete the folders.
To update projects and events on external drives
- Verify that the iMovie Projects and iMovie Events folders are stored on the top-level of the drive.
- Open iMovie.
- Choose File > Update Projects and Events.
After the update
After you update, your projects and events are placed in a new library, which you can see in the iMovie sidebar.
- Your updated projects are in the Updated Projects event.
- If you previously shared or finalized any of these projects, those video files will appear in the Finalized Movies event.
In the Finder, an iMovie Library file is created alongside your original iMovie Theater, iMovie Projects, and iMovie Events folders.
The files in these folders can still be opened by previous versions of iMovie. If you don't want to use these files in the future, delete the folders. Learn more about removing old libraries after you update.
To update later
If you choose Update Later, you can update projects and events by following these steps:
- Open iMovie.
- From the menu bar, choose File > Update Projects and Events.
- Click Update in the dialog that appears.
