Consolidating 2 iphoto libraries parents dating kids with disabilities
Open the "Picture" folder and copy the "i Photo Library" folder to an external drive, such as a thumb drive or external hard drive. IPhoto Library Manager merges two libraries and even offers an option to remove duplicate photos (link in Resources).
Consider using i Cloud to sync specific photos from your i Photo libraries.
If you're playing with Photos today but not ready to commit to it full time, maintaining a separate Aperture or i Photo library (or libraries), you may be wondering how you will ultimately merge your old Aperture and new Photos libraries together, should you want to do that in the future.
There's no “merge” function (just like there wasn't in i Photo), but there is a way to make this work.
All other i Photo libraries are present and still can be accessed through your Mac.
This way you can open Aperture and i Photo libraries while using any of the two applications.
Besides, the “unified’ format of libraries allows merging together all of your i Photo and Aperture libraries, to let you create one universal library containing all of your images.
As of OS X Yosemite, Apple is encouraging everyone to use its new Photos program for managing pictures in OS X.
While Photos has a number of pros and cons, it does share a limitation of its “i Photo” predecessor, in that while it uses a library system for managing photos and offers an option to create multiple libraries, it can only have one open at a time.
