I am looking to transfer an iMovie to an external hard drive. Any external drive that I attach shows up in iMovie but with a yellow triangle with the exclamation point in it. Any info on how to do this would be appreciatted.
Having trouble on my iMac exporting the movie so I would like to transfer it to a newer mac and export there.
