Re: "I am the administrator of my computer, but iMovie wants "read and write permission"
This permission may have to do with allowing iMovie to import video and audio clips or files etc. for use in movie composing, editing, or creation, etc.
Eg: Read and write permission is generally for files, folders, or maybe external hard drives. Eg: Some files on your Mac may be protected (via copyright etc.) by the file's creators, or by digital rights management (ie "DRM": management of legal access) :
If necessary: See how to: Change permissions for files, folders or disks on Mac
and / or
What to do: If you don’t have permission to use files on a Mac disk - Apple Support
