To combine Photos libraries, open the source library and export the photos and videos that you want to keep. Then open the destination library (the one that you want to use as your main library) and import the photos and videos.

Jul 25, 2011  18 ways to view the /Library folder in Lion and Mountain Lion. The reason for this move is presumably that people unfamiliar with the inner workings of Mac OS X. Dec 12, 2016  The User Library folder is hidden by default in MacOS Catalina, MacOS Mojave, macOS High Sierra, and macOS Sierra, but some advanced users may wish to show and access the /Library/ folder, which contains preference files, caches, and application support data.

Photos uses this library until you open a different one using the same steps.

All you need to do is hit Command+Shift+G from the Mac desktop (or Finder Go Go to Folder) and type in /Library to temporarily access the Library directory in the Finder.

These files are used by the applications on your Mac, and modifying them could change how the applications work. However, it doesn't hurt to explore the Library folder and see where some of the most essential files on your Mac are.

Export photos and videos from the source library

Open the source library, then decide whether you want to export your files as unmodified originals or edited versions:

Edited versions retain their edits when you import them. The advantage is that you don't have to recreate any edits; however, these files become the destination library's originals. This means that you can't revert to their earliest pre-import version.

Unmodified originals don't show any edits that you made when they were in the source library. This gives you flexibility for later editing, but recreating your edits might take substantial work.

How to export edited versions

1. In the Photos app, select the photos and videos that you want to export. To select multiple items, press and hold the Command key while you click. To select a group of items in order, click the first one, then press and hold the Shift key while you click the last one. This selects all of the items between the two that you clicked.
2. Choose File > Export > Export [number].
   
3. An export dialog appears.
   
   • In the Photos section, set Photo Kind to JPEG, TIFF, or PNG. JPEG recompresses your photos, which may result in smaller file sizes. TIFF and PNG files are higher fidelity and may result in larger file sizes.
   • In the Videos section, choose a Movie Quality setting. This section appears only if your selected items include videos.
   • In the Info section, select the checkboxes if you want to preserve metadata and location data in the exported files.
   • In the File Naming section, set File Name to Use File Name and set Subfolder Format to either Moment Name or None. Moment Name creates a subfolder for each Moment that's represented in your selected items. This is useful if you'd like to create an Album in the destination library for each Moment. The None option exports all of the files directly into the destination folder.
     
4. Click Export. A Finder dialog appears.
   
5. Navigate to the location where you want to save the files, such as the Desktop or an external drive. Click New Folder if you create a new folder for your exported items.
6. Click Export.

How to export unmodified originals

1. In the Photos app, then select the photos and videos that you want to export. To select multiple items, press and hold the Command key while you click. To select a group of items in order, click the first one, then press and hold the Shift key while you click the last one. This selects all of the items between the two that you clicked.
2. Choose File > Export > Export Unmodified Original.
   
3. An export dialog appears.
   
   • If your photos include IPTC metadata (such as titles or keywords) that you want to keep, select the Export IPTC as XMP checkbox.
   • Leave the File Name setting on Use File Name.
   • Next to Subfolder Format, choose Moment Name or None. Moment Name creates a subfolder for each Moment that's represented in your selected items. This is useful if you'd like to create an Album in the destination library for each Moment. The None option exports all of the files directly into the destination folder.
     
4. Click Export. A Finder dialog appears.
   
5. Navigate to the location where you want to save the files, such as the Desktop or an external drive. Click New Folder if you create a new folder for your exported items.
6. Click Export Originals.

How to import photos and videos into the destination library

Open the destination library, then drag the folder that contains your exported items into the main area that shows your other photos and videos. When a green plus sign appears on your pointer, you can release the folder.

The photos in the folder are sorted into Moments based on their creation dates and locations. The videos are sorted based on the date you exported them from the source library.

If you created subfolders when you exported the items and you want to create an Album for each subfolder, follow these steps:

1. In the Finder, open a subfolder.
2. Select all of the photos and videos within the subfolder.
3. Drag the items onto My Albums in the Photos sidebar.
4. Name the Album in the highlighted text box that appears in the sidebar.
   
5. Repeat for each subfolder.

Save space by deleting the source library

If you're sure that you've exported all of the photos and videos that you want to keep from the source library, you can delete it to save disk space on your Mac.

First, open the Finder and find the source library that you want to delete. By default, photo libraries are stored in your Pictures folder. If you can't find the library, follow the steps to choose a library; the path to the selected library's location appears in the Choose Library window.

Next, move the source library to the Trash. Then choose Finder > Empty Trash to permanently delete the files.
