Part 1. How to Merge iPhoto Libraries on Mac Manually

When you want to combine two or multiple iPhoto libraries on your Mac, you can choose to export them from iPhoto and then copy them to one same library. Before the libraries merge, you’d better create a full backup of your iPhoto libraries using an external hard drive.

Create a new folder to store all the merged iPhoto libraries. Open iPhoto and go to the first library you want to merge. If you want to import all photos from this library, you can press Command + A to select all files. Alternatively, you can open the specific folders or albums and choose the desired pictures. Click the File menu and use the Export option to copy them to the destination folder. Now, you can take similar steps to export pictures from the other library.

Once all iPhoto libraries are merged, you should take some time to review the imported photos. You can adjust the organization by creating albums, adding tags, or applying edits. For these duplicates, you can rely on the built-in duplicate detection tool in the Photos app to quickly identify and remove them.
