Using the iCloud Photo Library de-dupe feature they introduced. I had just under 2000 duplicates (Import mistakes and maybe some Aperture trickery back in the day perhaps?… no matter).
Looking over 19 years of Digital Photos, even just exposing ones for a cleanup task like this truly does make me more appreciative of the life I’ve been privileged to have alongside the people I’ve lived it with.
It’s really easy… too easy to forget that sometimes. And it’s something I need to keep more in the forefront of my ruminations on life.
