iCloud Storage is full.
I need to manage my icloud storage to avoid having to upgrade my plan. Any suggestions on how to move photos and videos from cloud to a different storage device?
Export photos from system photo library to a desired location say download folder in finder and connect an external hard drive to the Mac , then transfer the photos from download folders into the external hard drive , hence all your photo data is saved .
You can select few photos see this article Select and deselect photos in Photos on Mac - Apple Support and delete to recently deleted folder see this article Delete photos or recover deleted ones in Photos on Mac - Apple Support ( its your choice to delete them permanently immediately or after 30 days the photos will be removed from the iCloud server ) .
In this way the complete photo data is still on external hard drive , but the space is reduced in photo library .
