"Sync" Photos in one direction: Mac->iCloud, iCloud -> iPhone
Is this possible?
Update my iCloud Photos from my Mac (one direction: upload)
Download to my iPhone any iCloud changes (one direction: download)
Photos taken with iPhone camera should remain on the device.
Complete syncing would not prevent uploads of iPhone local photos to iCloud -- and their eventual addition to Mac Photos.
