Excellent with Aperture and Yosemite

It saving me tons of hours of time. It’s not a hard program, but you have to develop your work flow. Get to know the program. The ability to simultaneously compare photos across folders, libraries (inside and referenced) and drive (volumes)…match them exact or similar or grouping and auto marking according to criteria you set....are all incredibly useful. I’m still using aperture which is incredibly well supported.
