If you want to import photos from your Mac Photos library into Adobe Lightroom, there are a few things you need to do first. First, make sure that your Photos library is synced with Adobe Lightroom. If it isn’t, you can sync it by following these instructions. Once your Photos library is synced, open Adobe Lightroom and click on the “Import” button located in the upper-left corner of the screen. On the “Import Photos” dialog box that appears, select the photos you want to import from your Mac and click on the “Import” button. Adobe Lightroom will now start importing the photos into your library. It may take a while depending on how many photos are in your library and how large they are. Once the import process is complete, you will be able to see all of the imported photos in the “Photos” section of Adobe Lightroom. You can also use these imported photos as starting points for creating new photo albums or slideshows in Adobe Lightroom. ..
