iMovie 10.1 : Can't Delete Older Project

I've solved this in iMovie 10.1.5

I had this issue where the projects were showing as grey boxes which I could not delete. I opened a Finder window, went to my users/<username>/movies folder, right clicked on iMovie library and selected "show package contents".

In here I could see folders for the offending projects, so I deleted them.

When I restarted iMovie, it warned my me library was damaged, and I clicked on "repair" (not continue!).

Hey presto - undeleteable projects gone.

My existing projects were unharmed.

Hope this helps!

Hello Brandon,

Thanks for visiting Apple Support Communities.

Can you delete the troublesome iMovie project from the main Projects view? For reference, here are the steps from View and manage projects - iMovie Help:

1. In Projects view, move the pointer over the project you want to manage.
   

2. Click the button to the right of the name of the project you want to manage, then do one of the following:
   

   
   

   Delete the project: Choose Delete Project.
   

   

If not, what happens when you try? For example, do you see an error message?

Best Regards.

We aren't able to delete projects out of iMovie 10.1 either. We have gone through these steps and they won't delete. My husband is about to punch his imac. PLEASE HELP!

This is my problem too.

I have iMovie 10.1.1 and I have old projects that I want to delete but I cannot delete them. I can edit them, but I can not remove them from the projects screen.

Move to Trash, Delete Project....nada....

What do we do?

This doesnt work....already tried...my Mac does nothing when you click the delete option from that menu. Other options work, like rename, edit, etc.

When iMovie misbehaves sometimes deleting the iMovie preferences will straighten it out. Launch iMovie while holding down the command and option keys. This will bring up a window where you can delete the preferences. Just keep stepping through the windows that come up selecting continue until you get to the projects window. Then try deleting the project as described above. If that doesn't work it's probably time to reinstall iMovie.

To reinstall drag the iMovie app to the trash but don't empty the trash. Go to the App store and sign in with the Apple ID you used to purchase iMovie. Then go to the purchased tab and you should be able to redownload iMovie. If iMovie came with your computer when you purchased it from Apple then sign in to App store with the ID you used when you set up the computer.

A pic may help clarify

Please ignore this it got posted to the wrong discussion,

Is your library in the movies folder on your startup drive or on an EHD? If it's on an EHD try creating a new user, open iMovie and see if you can delete. If it's in your movies folder create a new user open iMovie and create a new trailer and see if it will delete. This should tell you if the problem is related to your Home Directory.

I was on the phone with Apple for 2 hours. We uninstalled and reinstalled iMovie. I still cannot delete the projects. Even when I delete them off the hard drive they still will not go away in iMovie.

As mentioned earlier (Jim Wanamaker), creating a Test User account on your Mac to then use that account to see if iMovie has the same issue is a good way to know if your iMovie issue is system wide or user account specific.

Has anyone booted into Safe Mode and tested iMovie to delete the project?

Start up in safe mode


1 Choose Apple menu ( icon at the top left of your screen) > Shut Down.

2 After your Mac shuts down, wait 10 seconds, then press the power button.

3 Immediately after you hear the startup tone, hold down the Shift key.

You should press the Shift key as soon as possible after you hear the startup tone, but not before.

4 Release the Shift key when you see the gray  Apple logo and progress indicator.

Safe mode won't work because iMovie requires OpenGL hardware and Safe Mode disables this.
