If you want to use iMovie on a Mac on campus, perhaps because you don’t have a Mac of your own, then you’ll need to take a moment to learn how to work with the associated projects and events files so that you don’t lose your work when you move from one lab computer to another.
Check out these instructions from Apple:
- Copy or move a project to an external hard disk
- iMovie ’11: Copy or move video from your Event Library to an external hard disk
If these handouts don’t give you all the info you need, try searching Google for more info.
