Open Apple Photos and select Preferences in the menu bar.

Click the General tab and select Use as System Photo Library under Library Location.

Select Use as System Photo Library. If it is grayed out, then it is already set as the System Photos Library.

Note:

• If Use as System Photo Library is grayed out, then the library is already set as System Photos Library.
• If you want to migrate the assets synced to your iCloud Library, click the iCloud tab and select iCloud Photo Library.
• Ensure that Download Originals to this Mac is selected, as the Photos migrator can only migrate photos for which originals are stored locally. Wait for all your originals to be downloaded before you begin migration.

Select 'iCloud Photo Library' to migrate assets that are synced to iCloud Library. Select 'Download Originals to this Mac' to allow migration of originals.

A Photos Library can be migrated to Lightroom only once. You can, however, migrate additional libraries. Also consider the following before you begin migration to Lightroom:

The migration of Apple Photos Library to Lightroom is supported in the following operating systems:

• macOS 10.12 (Sierra)
• macOS 10.13 (High Sierra)
• macOS 10.14 (Mojave)

Note:

In macOS 10.12 (Sierra), HEIC file formats are not supported.

• Folders and Albums
  • The hierarchy of folders and albums in Apple Photos Library is migrated to Lightroom. Shared albums and corresponding assets can also be migrated to Lightroom. Ensure that you select iCloud Photo Sharing to receive Shared albums data in your Photos Library.
• Bursts
  • Currently only the keyframe is migrated.
  • If you want all the Burst photos to be migrated, unstack them in Apple Photos first and then migrate them. To unstack and select Burst photos for migration, see View photo bursts and select shots to work with in this Apple document. After you've done this, the desired Burst photos will appear in your Photos Library which you can then migrate.

• Live Photos
  • The rendition of the still keyframe is migrated
  • The video is migrated

• Raw
  • Only the untouched original is migrated
• Portrait/Depth Effect
  • The untouched original is migrated
• People
  • Tagged people are migrated to Lightroom

Note:

• For Live Photos, since both the video and image components are migrated, the photo count in Lightroom is higher than what is shown in Apple Photos.

• The following assets are not migrated to Lightroom:
  • Shared Albums
  • Assets in Hidden Album
  • Assets in the Recently Deleted Folder
  • Assets in iCloud but not stored locally
• Raw

If you are using macOS 10.12 (Sierra) and have HEIC assets in your library, the HEIC assets are not migrated to Lightroom. This is because macOS 10.12 does not support HEIC files.

If you are using macOS 10.13 and higher and your library has HEIC assets, Apple Photos runs a background task to process these photos for migration. After the processing is complete, all the HEIC assets are ready for migration.

• In case the migration is executed before the processing of all assets is complete, few assets are not migrated to Lightroom.
• If all assets are not ready for migration, you can view a dialog box that states that all the assets are not migration-ready.

See Start migration to learn how to migrate your HEIC assets.
