Photos

The most recent version of Photos is Photos 4.0, the version that is installed by upgrading the system to macOS 10.14.2.

But upgrading to a newer system will not allow you to order the calendar from Apple, because Apple does no longer provide any print services at all since the first of october. If you upgrade to Photos 4.0 you will be able to create calendars in Photos using third-party project extensions. You can also try to convert the calendar using project extensions, but it may not be able to convert the calendar to exactly the same layout.

To get your calendar printed on your current version of macOS X, as it is now, save it as a PDF file and then upload it to Mimeo or Presto Photos. See this user tip: Ordering Books and Calendars on a Mac tha… - Apple Community

• Save your finished PDF book as a PDF file (https://web.archive.org/web/20170614002828/https://support.apple.com/en-us/HT201504 or Check and review a project before you order using Photos on Mac - Apple Support) and then send it to a service that can print books from PDF files.
  • 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
