Furthermore, the legal and ethical landscape of downloading iMovie DMGs from third-party sources is gray. iMovie is a "free" application provided by Apple to hardware owners, but it is not open-source. Distributing the DMG outside of Apple’s infrastructure technically violates the software license agreement. However, Apple does provide a legitimate "backdoor" for older versions: if a user has previously "purchased" iMovie (added it to their Apple ID), they can often download the last compatible version directly from their "Purchased" tab in the App Store, even if the current version is unsupported.
