El Capitan and Sierra iphoto albums
I was using Sierra and had about 3,000 photos in albums but I was having so many problems with Sierra that I went back to El Capitan. When I did that I lost all of my albums on iphoto. This week I upgraded to High Sierra and want to import my albums from my back up but don't know how to do that.
(FYI- after I downloaded High Sierra and opened my iphoto it asked if I wanted to import my pictures so I said yes but of course I didn't download them back into the albums. I don't know if I need to erase all of those before I try to add my albums/pics from my back up....
