can you still print a photo book from photos
Does photos still support photo book printing?
Apple is no longer offering any print products. But if you are running Photos 3.0 on High Sierra or Photos 4.0 on Mojave, you can install project extensions for Photos, that will allow you to order photo books out of Photos from third party print services.

If you cannot upgrade past Photos 2 on Sierra, see: Ordering Books and Calendars on a Mac that cannot be upgraded past El Capitan
