I may not be entering this discussion at the correct point, but I received an email from Mimeo yesterday that outlined how to convert or reprint existing Apple photo projects. I was very happy to hear this was possible, but must admit I am totally lost in the process!
1. I have downloaded the Mimeo app and it is now visible on my Photos menu and when I choose 'create', the Mimeo option comes up to create books, cards, etc. Gave it a test run - all seems good.
2. I have a photobook I created some time ago and I simply want to get a PDF copy of it, but when clicked on I still get the Apple message to download an extension from the App Store, even though I now have Mimeo in the system. If I 'continue' I get my book up, there is no 'Convert' button in the right-hand corner in order to select Mimeo Photos.
Also, for some unknown reason I can't get a PDF copy from within the book as I used to do (only prints a couple of pages - why is this?) and I even tried the menu to 'Export' a PDF, to no avail.
3. I have checked the 'Extensions' in my System Preferences and the Mimeo is one of the apps showing.
I have ver 3.0 Mimeo and MacOS High Sierra 10.13.6. Is it possible this wonderfully easy way to Convert a Photos book project into Mimeo is only available in the new OS software upgrade?
I have not even had the App Store new OS download offered on my computer, so I am assuming it is still in trial mode.
