Apple is shutting down its long-running Photo Print Products service, 9to5Mac has discovered, directing users instead to third-party apps on the Mac App Store that provide Photos extensions — a capability first introduced in macOS High Sierra. The service, which has been available since Apple first launched iPhoto in 2002, began by offering simple prints, later expanding to albums, photo books, and even calendars. Later this year, however, Apple plans to discontinue the service altogether, with a note in the macOS 10.13.6 Photos app that indicates final orders must be placed by Sept. 30, 2018, and pointing users to third-party apps on the Mac App Store that include Photos Projects extensions. The Projects section has also disappeared entirely in the macOS Mojave betas by default, with the File, Create menu now only providing links to a page on the Mac App Store that provides an overview of available extensions.
