Hi, cinsie,
Crashing can be caused by a number of things. Take a look at this thread for some diagnostic procedures that may help you solve it:
I assume that the
crashing is happening with all of your projects. If you have not tried opening
more than one project, try some others to rule out corruption that might be
confined to just one project.
If the crashing is
global, here are five procedures that you can try to address issue:
- Open iMovie while holding down the Option and Command keys and select to delete preferences in the box that appears. iMovie will open in a new library. Reopen your old library to get back to your projects. Now see if the crashing issue is solved.
2.If still no luck, try booting up in Safe Mode (see Finder help menu for instructions) and as soon as
everything loads immediately shut down and restart in normal mode. Sometimes
that clears out conflicts that cause crashes.
3.If the problem persists, try opening iMovie in a new library by opening iMovie while holding
down the Option key and, in the box that appears, choose a different library or
create a new library. See if that works. If you create a new library populate
it with a project or two to test.
4.Try opening iMovie in a new user account, either one you create or by using the Guest account on your
Mac. See if iMovie works properly there.
5.All else failing, try redownloading iMovie from the online app store. To do that, move your current
iMovie app from the Applications folder to the trash, but do not empty the
trash. Then go to the app store, sign in, and navigate to your Purchases folder
and redownload iMovie. If for some reason you can't get a new download, move
your old iMovie app from the trash to the Applications folder.
