Want to remove duplicate photos. Somehow there are 3 of most of my photos. Best and safest way to do that would be very helpful to know. I don’t trust many people for support, accept YOU.
Annually I offload some of my photos to an external drive. I do this to keep iMaC storage reasonable yet photos accessible by year on an external drive. those that I keep are part of my art portfolio. Something happened recently when I offloaded the 2020 photos. I found duplicated or tripled photos going back to 2004 on my iMAC only. the portfolio on my 2 iPads & iPhone are all intact. No Duplicates there. That’s the good news. I have plenty of room on my iMAC but would like to remove all these extra dupes. I make every effort to keep my iMAC from slowing down. Do you think these are ghost files on the Mac? Will these duplicates slow the Mac? should I delete these one by one? Last Question: I uploaded a 3rd party app “Photos Duplicate Cleaner” but was worried I’d mess up the Photos app. So I haven’t used it yet.
