Filmora Video Editor for Mac is one of the best iMovie alternative for Mac (macOS 10.13 High Sierra included) and Windows with all the basic editing tools, special effects and more advanced features. It has a more user-friendly interface than iMovie for you to edit video, make movie, adjust audio track, etc.
Follow this procedure to get the highest version of iMovie that your operating system will run. This assumes that at one point in time you had an earlier version of iMovie on your computer, though you might have deleted it:
To update/redownload iMovie 10, drag your iMovie 10 app from the Applications folder into the trash, but do not empty the
trash. (You can skip that step if you had iMovie 10 on your computer before, but deleted it.) 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 (if you moved it there) and return it to the Applications folder.
