Thank you for your continuing help with this problem, Cory. Per your latest advice I plugged the iPhone into my Macbook Pro and was about to open Image Capture. iPhoto opened automatically, as it does whenever the iPhone is plugged in. I attended to some other small task before opening Image Capture, but when I looked back at my computer screen—before opening Image Capture—I saw that iPhoto was displaying all the photos on my iPhone! Go figure! The only thing I did differently was that my external hard drive was not plugged in. I have a small iPhoto library on my Mac and a much larger one on the external HD.
So I unmounted the iPhone, quit iPhoto, mounted the external HD, and plugged in the iPhone again. iPhoto, the one on the Mac, opened again, but this time it showed no photos on the iPhone, which is the original problem. I then opened Image Capture. It too showed “0 items” on the iPhone.
I then unmounted the iPhone, quite Image Capture and iPhoto, and unmounted the external HD. Then I plugged in the iPhone again. I expected iPhoto to open and show me the iPhone photos, but even after unmounting the external HD iPhoto did not display the iPhone photos. So I again unmounted the iPhone. Then I restarted the Mac and plugged in the iPhone. IPhoto opened but still did not see any photos on the iPhone.
Finally, I powered off the iPhone, powered it up again, and plugged it in. iPhoto still did not see the photos. I have over 250 photos on the iPhone, some of which were taken as recently as yesterday.
So I got lucky one time for no apparent reason.
I am reluctant to upgrade the Mac OS because I have other applications that I frequently use which are probably not compatible with systems beyond Mavericks. One such ap is iWorks ‘09, especially Pages 4.3 and Numbers 2.3. (Pages 5 is not an option. It looks like a dumb-down ap to me. And although I use Word when necessary to send documents to my clients, it—like other Microsoft products—is unnecessarily obtuse. I despise it!) I realize I will eventually have to upgrade, but something keeps telling me don’t do it yet. Not yet.
