iMovie troubleshooting

Is this happening with just one project or with all projects? Do you get a timeline after creating a new project?

If you close out of a project and then go to Media view, there won't be a timeline displayed.

Here are some diagnostic things that you can try:

Try booting up in Safe Mode (see Finder menu for instructions) and, after

everything loads, immediately boot up in normal mode. See if that cures it.

Also, you can try opening 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 empty library. Reopen your old library to get back to your

projects. Now see if the timeline displays.

If neither of the above procedures solve it, try redownloading iMovie. To do

that, drag your iMovie app from the Applications folder into the trash, but do

not empty the trash. Then 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. Redownload/update iMovie

from there. If not successful, drag your present iMovie app out of the trash

and return it to the Applications folder.
