I think this is how:
- Switch to Finder.
- Right-click on your Photos library and select Show Package Contents
- Drag the Masters folder from inside the Photos package and drop it in Pictures - ie make Masters into a regular folder
- In Lightroom, import the Masters folder, choosing Add in the Import dialog
With this method you can import some or everything. I suggest everything, and then forgetting about Photos.
It would be great if you could confirm this method worked.
I just used this method. Thank you, it worked well. One question though: I have 20,000 photos. Are there now two copies on my hard drive and in using my iCloud data? Would you then delete them all from apple photos?
John - This was very helpful. Thank you for taking the time to post.
