Thank you, Nik. Files called Locations.rpbookmarklist, Favorites.rpbookmarklist, and singleFileEditor.rpbookmarklist did not exist in my case. However, the two plist files did exist and removing them seems to have fixed the issue. I was able to browse files in various albums in my Apple Photos system library. However… once I happened to view an album that contained some videos, and I happened to click on a thumbnail representing a video, the same beach ball appeared again, and RAW Power is once again unresponsive. Are videos not supported at all? Or just referenced videos?
Couple additional clarifications, if you don’t mind:
– all of my photos are referenced, but I do not see any overlay icons on top of thumbnails indicating that files are referenced? (Apple Photos does mark references images). Is there a way to visually tell within RAW Power that a photo is a referenced one?
– if I am running RAW Power as a standalone app and view my existing Apple Photos library. Where would it store all the edits? Into that Apple Photos library, right?
– if I am running RAW Power as a standalone app and view photos in a set of directories (not in the Apple Photos library), then all the edits would be stored in the RAW Power application sandbox and photo files themselves will be completely untouched, right?
