I can't upgrade my photos App! Help in time for x-mas.
My daughter created two photo books in the Photos App on my MacBook Pro which is running OS X El Capitan Version 10.11.6.
When we try to "buy book", a window appears that says I need to "upgrade Photos to the latest version" to complete the purchase. The Photos I am currently running is version 1.5, last modified Wednesday, November 9, 2016.
I have been unable to find any way to upgrade Photos. I have been to the App Store, checked "Updates," and checked "Purchased." In neither place is there an option to upgrade my current Photos App. In "purchased," there is a 2014 version of iPhoto that is available to open, but obviously this is no longer what I am using.
Please tell me how to order and purchase the photo books my daughter has created in time for X-mas.
