How to get imovie 10.1.7 update file

Hi,

Try this procedure to download the highest iMovie version that your HIgh Sierra operating system can run. I believe that would be iMovie 10.1.7 or 10.1.8.

To update/redownload iMovie 10, drag your iMovie 10 app from the Applications folder into the trash, but do not empty the trash. Sign in to the app store and open your purchases folder by clicking on your name at the bottom of the app store side bar. You will see your purchases displayed, including iMovie 10. Redownload/update iMovie from there. If not successful, drag your present iMovie app out of the trash and return it to the Applications folder.
