How to Fix iMovie Keeps Crashing When Importing or Exporting

iMovie is a go-to video editor for Mac and iOS users, but frequent crashes during importing or exporting can ruin your creative flow. Imagine spending hours editing a project only to see iMovie freeze during export, or worse, shut down abruptly while importing vacation clips. These issues are frustrating but fixable! Below, we explore why iMovie crashes and provide actionable solutions, plus a reliable alternative to avoid headaches entirely.
