Sync highlights and notes between iPhone, iPad, and Mac

| Device or system | Settings path | What to enable |
|---|---|---|
| iPhone or iPad with iOS/iPadOS 18 or later | Settings > [name] > iCloud; then Settings > Apps > Books | Under iCloud, enable iCloud Drive and Books. In Books settings, enable Home and iCloud Drive. |
| Older iPhone or iPad systems | Settings > [name] > iCloud; then Settings > Books | Under iCloud, enable iCloud Drive and Books. In Books settings, enable Reading Now and iCloud Drive. |
| Mac | System Settings, iCloud Drive settings, and Books > Settings | Enable Books under iCloud Drive. In Books settings, enable Reading Now and “Collections, bookmarks and highlights.” |
