Apple promised that when we identified people in Photos in iOS 10 or macOS 10.12 Sierra, it would sync and merge this special album’s contents across all our linked devices. Oops! Well, it finally made it into iOS 11 and High Sierra, at least.
Macworld reader Gerry was looking forward to this working, but finds that his various devices never sync up, no matter how long he takes or how much he observes the Photos’ apps instructions to wait.
However, Gerry doesn’t use iCloud Photo Library. He says, “If iCloud Photo Library is required, then nuts!” Have some pistachios, because that feature is required. On every device on which iCloud Photo Library is enabled and you’re connected with the same iCloud account, Apple passes various information related to photos and videos.
