Prepare your drive

  2. In the Finder, go to the external drive where you want to store your library.

  6. If you use iCloud Photo Library, designate this library as the System Photo Library.

Delete original library to save space

After you open your library from its new location and make sure that it works as expected, you can delete the library from its original location.

In a Finder window, go back to your Pictures folder (or whichever folder you copied your library from) and move Photos Library to the trash. Then choose Finder > Empty Trash to delete the library and reclaim disc space.

Open another Photos library

If you have multiple libraries, you can open a different one like this:

  2. Press and hold the Option key while you open Photos.
  3. Select the library that you want to open, then click Choose Library.

Photos uses this library until you open a different one.
