Printing from Photos using macOS10.12.6
On my older (mid-2011) iMac running osMac 10.12.6, I've created a calendar in Apple Photos and wish to have it printed and shipped to me. However, Apple tells me I can't without upgrading my OS to High Sierra (10.13). For compatibility reasons with other programs / Apps I use regularly, I do NOT want to upgrade to 10.13. How can I continue to print a calendar or photobook from Photos (version 2.0) without upgrading to 10.13? Are there existing 3rd party extensions available for Photos, or other applications that will accept Photos projects such as calendars that will allow me to do that?
