Only one mention of Aperture, suppose I can be the second one to also lament the loss. Lightroom never grew on me and I still miss the UI and workflow of Aperture.
Might give this a try. I just keep on holding back because I do not want to lose all my thousands upon thousands of edits.
Just this morning I was missing Aperture and mentioned it to my kids. I was organizing some pictures with Photos.app and adding a tag or removing from an album takes about 5 seconds for the UI to visually represent my change. I have a decently big library but certainly not anomalous. Aperture made it so fast to organize and deal with photos.
