The ultimate toolbox for Photos on your Mac

PowerPhotos works with the built-in Photos app on your Mac, providing an array of tools to help you get your photo collection in order.

Create and manage multiple libraries

Instead of being limited to putting all your photos in a single library, PowerPhotos can work with multiple Photos libraries, giving you many more options for how to organize your ever growing photo collection.

Splitting your photos between multiple libraries helps Photos open more quickly, lets you archive older photos, store some of your collection on an external hard drive, and reduce storage space used by iCloud Photo Library.

Copy photos and their metadata

You can split your library by copying albums and photos with a simple drag and drop. PowerPhotos will take care of copying the photos and retaining their metadata, including keywords, descriptions, titles, dates, and favorite status. Read more about what PowerPhotos can copy.

Merge Photos libraries

Got a whole bunch of libraries you want to consolidate into one? PowerPhotos lets you merge your libraries together while weeding out duplicate photos in the process. You will be shown a preview of what your merged library will look like before any modifications are done, to ensure your merged library looks how you want.

Find duplicate photos

It's easy to have multiple copies of the same photo creep into your photo collection over time. Use PowerPhotos to find duplicate photos in one or more libraries, view them side by side, and separate them into albums where you can easily delete them from your library.

Browse and search

Use PowerPhotos' image browser to quickly view your photos without having to open Photos itself. View detailed photo information using List View, and search for photos across all your libraries at once.

Migrate your iPhoto/Aperture libraries

If you have a lot of existing iPhoto or Aperture libraries that you want to migrate over to Photos, PowerPhotos will help automate your migrations so you don't have to spend time babysitting this lengthy process.

Photos in your System Photo Library are available in apps like iMovie, Pages, and Keynote. You can also sync them to iOS devices and view them on Apple TV. And if you want to use your own images as your desktop picture or screen saver, the images need to be in your System Photo Library before you can select them in System Preferences.

If you have only one photo library, then it's the System Photo Library. Otherwise, the first photo library that you create or open in Photos will become the System Photo Library. If you have more than one library, you might need to designate a System Photo Library, so other apps can access the photos and videos you want them to use.

Merge Photos Library Mac

Follow these steps to designate a System Photo Library:

1. Quit Photos.
2. Hold down the Option key and open Photos. One of the photo libraries is already designated as YourLibraryName (System Photo Library).
3. Choose the library you want to designate as the System Photo Library.
4. After Photos opens the library, choose Photos > Preferences from the menu bar.
5. Click the General tab.
6. Click the Use as System Photo Library button.
   

If you open a second or different library in the Photos app, and you haven't designated it as the System Photo Library, other applications will use photos from the original System Photo Library. Hold down the Option key when you open Photos to see which library is set as the System Photo Library.

If you designate a new library as the System Photo Library and then turn on iCloud Photos, the photos and videos in the new library will merge with those already in your iCloud Photos. If you want to keep the contents of your photo libraries separate, don’t turn on iCloud Photos for more than one library in Photos.
