Trouble transferring photos from iPhone13 pro to iPhotos on a MacBook pro
I am using a late 2016 MacBook pro running Mohave 10.14.6 and an iPhone 13 pro max with iOS 15.2
When I take photos only a few of what are visible on my new phone will display in iPhotos on my computer. When I transfer them they are removed from my phone (with that option selected). iPhotos then shows my phone to have no photos despite my phone showing more exist.
If I unplug the phone from the computer and plug it in again more photos will show up and I can download them to the computer. But still not all of them.
Today it took repeating this six times to get the newest batch of photos from my phone into iPhotos. This occurred in increments displaying on the computer and with corresponding transfers containing 6, 10, 8, 17, 31, and 9 photos each. (All were taken immediately before transferring to my computer)
iPhotos has also shuffled them wildly and does not display or download them in the order they were taken.
Any idea what is going on or how to fix this. I can certainly work around all of that but it would be nicer if it worked right. My iPhone 7 does not have this problem.
