imovie 10.0.9 crashes after El Capitan update

Hi There,

I had the exact same problem as you. Here's what I did. Go to the app store and make sure iMovie is in the "purchased" tab. If it is delete the app and then re-download the app from the app store.

My model:

Macbook

Mid 2015

OS X El Capitan Dev. 10.11.1

Please let me know how this works out.

Worked for me. Thanks!

I did a complete uninstall of iMovie using CleanMyMac 3, rebooted then downloaded iMovie again.

Hi Michael

I took your advice, and deleted the app (it was in my 'purchased') but when I went back to the app store it only gave me the option to 'update' and it wont update... it just spins and spins... do I need to do more to delete all tracks of imovie, and if so how?

I Have the same problem and tried this but it didn't work. I deleted iMovie from launchpad. Is there another way to uninstall it.

What do you do if it's not in purchased folder? El Capitan has been a huge headache for me. Photoshop Elements has been crashing too.

Go to the App Store and download again. It's free,

This worked for me - thanks a zillion - but what a pain to have to do it at all. Black mark for Cupertino!

I had this problem too and because of that, did not update my 2 video processing workhorses.

I just updated to the latest 10.11.2 on my MBP and now iMovie 11 (9.09) works as before, no crashing and no upside down thumbnails!

Have you tried importing a still shot (photo)? If this works okay for you, you will be the first I have found in a month of searching that can run El Capitan and iMovie v9.

Just tried importing a photo. Did 2, both worked fine. also imported some video and that worked too. So far, so good since I deleted the original (using CleanMyMac) and reimporting from the App store as suggested by Michael _88_88 (above)

Keeping fingers crossed.

Did you delete any of the Libraries you had created in iMovie v10? And did you empty the trash before downloading and re-installing iMovie v10?
