Back up your library
Oct 25, 2019 How to switch between Libraries in Photos for Mac. When you create a new library, you may still want to go back to a previous library for something. Fortunately, it's easy to switch between multiple libraries. Make sure that Photos is not open (quit if it is). Hold down the Option key on your keyboard. Double-click on Photos.
Before following any of these steps, it's a good idea to create a backup of your photo library, even if you use iCloud Photos. You can use Time Machine, use a third-party backup solution, or copy the library to an external drive. By default, your photo library is stored in the Pictures folder within your home folder.
Make sure that your software is up to date
Photos is part of the Mac operating system. You can avoid or fix many issues by running the most up-to-date version of macOS. Learn more about updating the software on your Mac.

If you have trouble migrating an existing iPhoto or Aperture library to Photos
You might see an alert message when you first open Photos or migrate an existing iPhoto or Aperture library. Learn what to do if Photos can’t copy or create a library.
If the Media Browser isn't showing your photos and videos
Use the Media Browser to make images from your photo library available in other apps, like Pages and iMovie. The Media Browser shows only the contents of the Photos library designated as the System Photo Library. If you have more than one Photos library—and the one you're using isn't set as the System Photo Library—the Media Browser won't show its contents.
Follow these steps to designate the current library as the System Photo Library:
- Choose Photos > Preferences.
- Click the General button at the top of the Preferences window.
- Click Use as System Photo Library.
