My iCloud account is already set up and contains several years worth of photos.
If I log in to my iCloud account from a new iPad, I understand that only the last 60 days worth of photos will be downloaded to the iPad.
But I had also understood that if I log in to my iCloud account on new Macbook, all the iCloud photo library, not just the last 60 days, will appear in iPhoto/Photo (after setting the appropriate iCloud System Preferences, and the iCloud preferences within iPhoto/Photos).
Yet even on a Mac I am only getting the last 60 days of photos. How do I get iPhoto/Photos to download the full iCloud photo library?
