You can import your Apple iPhoto and Aperture libraries into your Lightroom Classic CC catalog. Here's how.
It is recommended that you back up your Lightroom Classic CC catalog before proceeding.
Your iPhoto or Aperture library will be automatically detected. You have the option to select a different library, if applicable.
Your images will be copied to a new location. A default location is listed but you have the option to choose a different folder.
Additional options are available for how Lightroom Classic CC will work with available previews, keywords, color labels, and stacks.
To import photos from iPhoto into Lightroom Classic CC, first you have to help Lightroom Classic CC find the original photos, which are hidden in a package file. Then, you can copy or add the photos to a Lightroom Classic CC catalog just like you would import any other photos from a folder on your computer.
Note: These instructions are for iPhoto '11 version 9.2.
Open Lightroom Classic CC and drag the Masters copy folder into the Grid view of the Library module.
The import window opens, with your iPhoto files selected in the preview area. By default, Lightroom Classic CC wants to add these photos to your catalog. Choose Copy or Move, if preferred, and specify the destination folder and other options in the panels on the right-hand side of the import window.
