Mac photo backup
Helllo
So I have recently upgraded from iphone 6s to iphone X, however I noticed that when I take a photo on my iphone X ..it DOES backup to the icloud but is not showing in the photos app on the Mac.
It was working fine before so I am not sure what has changed. My old iphone 6s is still sigined in with my Apple ID.
I noticed on the photos app on my Mac that the iCloud option was not enabled under prefereces. However when I try to enable it, it wants to upload all my photos from my Mac to the cloud even though they are already in the cloud, it started to do this and has started to create duplicates...
How can I like my Mac to Icloud without it trying to sync all my existing photos thus creating thousands of duplicates?
