How To Rebuild Mac Photo Library

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.

Jun 23, 2015  Photos is Apple's photo-management app that recently replaced iPhoto with the release of OS X Yosemite 10.10.3.

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.

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.
