Imovie

Hi, swatisan14,

Try this procedure:

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. (NOTE: For El

Capitan and older, click on the Purchases tab at the top of the app store

screen and then sign in. Click on Purchases again to reveal your

purchases.)  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.
