System upgrade to macOS Sierra successful.

macOS Sierra is macOS 10.12. It does not yet support the project extensions. You need to go to all the way to macOS 10.13 High Sierra or macOS 10.14 Mojave.

Here is a link to the Mojave upgrade: macOS Mojave - Apple

The system requirements for Mojave are here.

The Mac needs to have a Metal-capable graphics processors (GPUs).

Mac Hardware Requirements

For details about your Mac model, click the Apple icon at the top left of your screen and choose About This Mac. These Mac models are compatible with macOS Mojave:

• MacBook (Early 2015 or newer)
• MacBook Air (Mid 2012 or newer)
• MacBook Pro (Mid 2012 or newer)
• Mac mini (Late 2012 or newer)
• iMac (Late 2012 or newer)
• iMac Pro (2017)
• Mac Pro (Late 2013; Mid 2010 and Mid 2012 models with recommended Metal-capable graphics cards)

Better make two backups, before you upgrade and burn your bridges. Tere may be other device drivers and applications that are no longer compatible, if you are far behind.

The error message is misleading.

Apple does no longer accept orders for printing books or calendars or cards. The last orders should have been submitted by September 30.

You can now only order books in Photos using third-party project extensions. See: Old Toad: Post 9/30/2018 Printing Options for Photos

• Use Project Extensions to order print products in Photos after September 30, 2018
• Create and order print products in Photos with Project Extensions https://support.apple.com/en-us/HT208920

But using the project extensions requires to upgrade to Photos 3.0 or 4.0, and that can only been done by upgrading the Mac to High Sierra or Mojave.

To get to a new, major system version macOS 10.13 or macOS 14, you need to download and install a system upgrade. That is not an incremental system update.

The upgrade to macOS 10.13 High Sierra with Photos 3.0 can be downloaded here: Upgrade to macOS High Sierra - Official Apple Support

The upgrade to macOS 10.14 Mojave with Photos 4.0 is available from this site, if your Mac supports it: macOS Mojave - Apple

if you do not want to upgrade your Mac, you can save a PDF preview of your finished book and have it printed by a local store or an online service like Presto Photos (Photo Book Printing, Color Book Printing, and Calendar Printing - PrestoPhoto).

This is described here: https://help.apple.com/photos/mac/1.2/?lang=en#/pht6e15caf3https://help.apple.com/photos/mac/1.2/?lang=en#/pht6e15caf3

The High Sierra page is here - I am not sure about the requirements: https://support.apple.com/macos/high-sierra

I would ask in the High Sierra forum (https://discussions.apple.com/community/mac_os/high_sierra) for support with upgrading. Our system experts are there. Or if you want to add memory or a different graphics card to your iMac, the users in the iMac forum https://discussions.apple.com/community/desktop_computers/imac_intel

may be able to help.

I got help from turingtest2 on this. He found this page on the wayback machine with the requirements for High Sierra: https://web.archive.org/web/20180923200326/https://support.apple.com/en-us/HT201 475
