All your photos on all your devices. ICloud Photos gives you access to your entire Mac photo and video library from all your devices. If you shoot a snapshot, slo-mo, or selfie on your iPhone, it’s automatically added to iCloud Photos — so it appears on your Mac, iOS and iPadOS devices, Apple TV, iCloud.com, and your PC. Oct 25, 2019 How to move your Photos library to an external hard drive. If you're low on storage space on your Mac, you can just move your Photos Library to an external hard drive. Keep in mind though, that you will need to have this external drive plugged in to access your Photos Library, even if you have iCloud Photo Library enabled. Jan 12, 2020  You can access the hidden Library folder without using Terminal, which has the side effect of revealing every hidden file on your Mac. This method will only make the Library folder visible, and only for as long as you keep the Finder window for the Library folder open.

Even if you use iCloud Photos, it’s important that you always back up your library locally using one of the following methods:

  • Use Time Machine: After you set up Time Machine, it automatically backs up the files on your Mac. If you ever lose the files in your Photos library, you can restore them from the Time Machine backup. For more information about setting up Time Machine, see Back up your files with Time Machine.

    WARNING: If a Photos library is located on an external drive, don’t use Time Machine to store a backup on that external drive. The permissions for your Photos library may conflict with those for the Time Machine backup.

  • Manually copy your library to an external storage device: Drag the Photos library (by default in the Pictures folder on your Mac) to your storage device to create a copy.

If you have more than one photo library, be sure to back them all up.

Important: If any of your image files are stored outside your photo library, those files (known as referenced files) aren’t backed up when you back up your library. Be sure to back up those files separately. To make it easier to back up all your image files at once, you can consolidate referenced files into your library. See Change where Photos stores your files.

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.

Choose a photo library

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:

  1. Press and hold the Option key as you open the Photos app.
  2. 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

  1. 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.
  2. Choose File > Export > Export [number].
  3. 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.
  4. Click Export. A Finder dialog appears.
  5. 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.
  6. Click Export.

How to export unmodified originals

  1. 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.
  2. Choose File > Export > Export Unmodified Original.
  3. 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.
  4. Click Export. A Finder dialog appears.
  5. 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.
  6. 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:

  1. In the Finder, open a subfolder.
  2. Select all of the photos and videos within the subfolder.
  3. Drag the items onto My Albums in the Photos sidebar.
  4. Name the Album in the highlighted text box that appears in the sidebar.
  5. Repeat for each subfolder.
