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.
How to Combine Multiple Photos Libraries Into a Single Library Saturday, July 1st, 2017 Author: Tom Nelson. If you’ve been working with the Mac’s Photos app (or even the older iPhoto or Aperture apps) for any length of time, there’s a good chance you have multiple image libraries to. Sep 03, 2015 Switching libraries. With multiple libraries on your Mac, you can switch between them very easily using two methods. The first is using the same library manager, so simply quit and relaunch Photos with the Option key held, and you can then select your library.
Choose a photo library
Here's how to open one of the multiple photo libraries that you might have on your Mac or on a connected external drive:
- Press and hold the Option key as you open the Photos app.
- Select the library that you want to open, then click Choose Library.
Photos uses this library until you open a different one using the same steps.
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
- 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.
- Choose File > Export > Export [number].
- 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.
- Click Export. A Finder dialog appears.
- 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.
- Click Export.
How to export unmodified originals
- 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.
- Choose File > Export > Export Unmodified Original.
- 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.
- Click Export. A Finder dialog appears.
- 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.
- 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:
- In the Finder, open a subfolder.
- Select all of the photos and videos within the subfolder.
- Drag the items onto My Albums in the Photos sidebar.
- Name the Album in the highlighted text box that appears in the sidebar.
- 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.

I've had a multi-Mac household pretty much since college, rocking a laptop and desktop in addition to miscellaneous iOS devices throughout the years. Dropbox and iCloud sync made most of the pains of using several Macs disappear, but iPhoto was always a problem. My laptop is tiny! My iPhoto library, not so much.
Thankfully, Photos for Mac — paired with iCloud Photo Library's Optimize Storage feature — makes working with and syncing multiple Macs a breeze. Here's how you can do it.
How to use Photos and iCloud Photo Library with multiple Macs
Here's a quick, simple breakdown on setting up your Macs to support Photos and iCloud Photo Library.
I recommend starting with your biggest iPhoto library; it'll usually be on your desktop Mac. When you open Photos for the first time, your library should import automatically; if it prompts you to create a new library, your Photos library may be stored in another location on your Mac, and you may need to manually open it.
Once you've imported your biggest library on your Mac, make sure iCloud Photo Library is turned on and syncing. You can do this by following these steps:
- Launch Photos on your Mac.
- Click Photos in the menu bar.
- Select Preferences (or do this quicker by pressing ⌘,).Source: iMore
- Click on the iCloud tab.Source: iMore
- Check off the box for iCloud Photos.
- You can also check off the box for Download Originals to this Mac if you have the space.
- You can check off Optimize Mac Storage to save space on your Mac by only saving a percentage of images and video locally — the rest will be thumbnails that you can click on to download when you want to.

Now, open your other Mac, and launch Photos. If you have an iPhoto library on that secondary Mac, follow the same steps as above — import your library, then turn on iCloud Photo Library. If you have duplicates of the same photo on each computer, iCloud should automatically resolve those conflicts when it syncs, providing you with just one version of your photos when the sync process finishes.
If you don't have an iPhoto library on your secondary Mac, create a new library in Photos and turn on iCloud Photo Library. If you want to save storage space on this secondary Mac, make sure Optimize Mac Storage is selected: This will save a certain percentage of images and video locally to your device, while providing thumbnails of all the others for you to download at your leisure.
After you've set up all your Macs with Photos and the sync process has finished, you're now good to go. From here on out, any time you add photos, they'll sync to every computer you've set up with Photos.
What syncs, what doesn't sync
Photos for Mac syncs a lot more than just your original photos and videos. According to a support document on Apple.com, here's what else you should expect to see sync:
- All folders and albums
- Smart Albums
- Keywords
- Memories
- Searchable keywords
- Key photo selections
There are a few things iCloud Photo Library won't sync, however. Here's Apple's list:
Where are the photos I imported into Photos on my Mac? By default, the photos and videos you import into Photos are stored in the Photos library in the Pictures folder on your Mac. When you first use Photos, you create a new library or select the library that you want to use. This library automatically becomes your System Photo Library.
