iPad failure to sync because of Photos
In trying to sync my iPad to my iMac the process gets hung up for hours at step 5 of 6 "Reading Photos Library". I've run the "repair library" process, tried limiting the photos sync to only a few albums, tried "skip photos" during sync, but nothing breaks breaks the process beyond step 5. I am also unable to eject my iPad at that point. Disconnecting the iPad results in the sync process not even getting beyond "reading iPad" next time I connect. I have over 20,000 photos in my Photos library, some of which are referenced, so I don't know if that's causing the problem.
