what about iPhoto?
I have an older macbook Pro with OX X Capitan version 10.11.6 and a Mac mini (late 2012) with macOS high sierra version 10.13.4 that I have been using for my numerous photos, making annual family memory books, albums etc since 2009. I tired to follow the steps to upgrade my current work (family album 2018) however, iPhoto does not offer the option to upgrade present work as explained in the mail apple sent out stating the steps necessary to follow. How should one proceed? I usually send the yearly album offer on Jan 1st with the previous years pictures. HELP!
