Creating a photo book with apple on MAC

You can no longer order books from Apple at all. The last orders for books had to be placed by September 30, 2018. If you upgrade to macOS 10.13 or macOS 10.14 you can use third-party project extensions to order books from third-party services.

Since your Mac is stuck on El Capitan you may want to save your existing book as a PDF file and send them to a service, that can print Apple Books from PDF files, see: Ordering Books and Calendars on a Mac that cannot be upgraded past El Capitan

• Mimeo used to print for Apple and can handle PDFs created in Photos, see: https://import.mimeophotos.com
• Also Presto Photo can print from Apple https://www.prestophoto.com
• If you are not located in the US, there may be local printing services, which would be more economic with respect to international shipping fees and shipping time. In Germany we can use photographerbook to print existing Apple PDF files: https://www.w2p-photographerbook.de/fotobuch-aus-aperture-iphoto-fotos
