Until 2017 I took pictures with mi iPhone using local storage, and then I saved them to my Macbook using Photo.app. But since 2018, I started to use on the iPhone the option to store pictures on iCloud. Since then I did not use Photo.app backup and now I want to do it.
I wonder if I will have some sort of problem since on my iPhone and using local storage I do not have all copies of my pictures, but they are all supposed to be on iCloud. How should I do this so that I am sure that all new pictures are transferred to Photos.app?
