I am on High Sierra 10.13.6 and using Photos for Mac. When I open Photos for Mac all of my albums show up on the left side of the Photos app, however they have no photos in them, each album says it 0 photos. I have repaired the library 2x however that did not fix the problem. The Photos library is on an external HD. Any idea how I can recover the photos?
By the way, I have logged into my iCloud.com account and see all the photos up there however they are not showing in the Photos for Mac app.
