I am trying to set up my half's iPhone and Mac in a way that the photos are synced to the Mac automatically over the WiFi, at the same time free up space once it becomes full as it's only the 16GB model.
I thought iCloud Photo Library would do the trick but when I enable it on the Mac it wants to upload the entire existing photo library from the Mac first.
I just want it to go one way, iPhone -> iCloud -> Mac, is it possible to set it up this way?
If not possible can I create a second photo library that is blank on the Mac and contains just the iPhone photos? I would rather not but if this is the only way.
Could/should this be handled by iTunes instead? Can it be used, last time I owned an iPhone it handled this but it looks like it's shifted responsibility to iCloud/Photos, is that correct?
Backup is handled by Time Machine on the Mac and the Photo app is used for viewing/managing photos.
