No, my problem is NOT solved: still can't sync some photos to iPad Pro from iMac
I posted this question yesterday, and after one response (which was not helpful, though I do appreciate Rudegar's having tried to help me), mysteriously my question was marked as "Solved" in the list of questions, so it's unlikely that more people will look at that thread. I can't figure out how to remove that "Solved" label, so I'm posting my question again.
I'm trying to sync selected photos from my iMac (running Mavericks 10.9.5) to my new iPad Pro (12.9 inch model, updated to iOS 9.3.1). I connect the iPad to the iMac, fire up iTunes (version 12.3.3.17, it says), select the iPad in iTumes and then the "Photos" tab over on the left. On the right I choose "Selected Folders," and in the "Folders" window below that I check the boxes for the folders that I want and click on "Apply" if it's there or "Sync" if that's the only option showing.
Every time, a few photos refuse to move over to the iPad. It's always the same ones, but I can't find any common characteristic (e. g., wrong extension or huge file size) that would explain why those photos won't go while everything else will. Typically in a folder with 20 photos, between 15 and 20 will move over to the iPad. But why won't the rest? This is really bugging me. I've tried unplugging and replugging the iPad, turning it off and on, quitting and restarting iTunes, and even putting the ones that won't sync into a special folder all of their own. No luck.
Can anybody help me out?
iPad Pro, iOS 9.3.1
