Photos doesn't show all the photos in any library
Hello,
I am trying to help my wife see all of the photos on her Mac so she can remove duplicates and save the ones she wants, but I've got very little knowledge of Macs (very strong knowledge of PC's).
When I open Iphoto there are three folders all with between 15-26MB of photos, but they all have 3-4 photos in each, which is clearly not all of them. Also, one of the folders won't open at all but says that the photos were migrated already, who knows where.
We are doing this so that she can safely move all the photos to an external hard drive so we can do the BigSur update as the mac is currently running Catalina right now.
