I have an older version of photos on Imac . I am running El Capitan version 10.11.6, and Photos version 1.5
I just completed a photobook, and when I clicked buy book, I got a message that I cant order because my version of Photos is too old.
How do I upgrade photos? I tried to google it, but I didnt help.
Do I need to upgrade the entire OS?
Any advise would be great. The book is supposed to be a gift, which now I don’t know if I can get it in time.
