Is there a way to decouple photos from iCloud in the Photos application when they arrive? Basically, on macOS, I would like iCloud to deliver new photos and otherwise leave my local photo library alone. If this is not possible, is there a work around, such as a method for creating independent copies of photos that arrive via iCloud?
I have found similar questions that explain that iCloud tightly couples photos across devices but nothing about how to work around the problem. Clearly different devices have different storage capacity, so it makes sense that one would like to enforce different policies on each device.
