Since I came to Thailand 6 weeks ago, iPhoto on my Macbook pro has been scanning for faces. On my Mac Pro desktop, this process took about 2 days as I recall. My iPhone 7 Plus, which I bought a week ago is almost finished. This time it’s incredibly slow. I am so sick of seeing this screen:


I’ve started tracking my progress:
2016-12-22 21:59: 9521 photos left to scan when I quit
2016-12-24 19:04: 16232 photos scanned, 8771 photos left when I quit
2016-12-24 22:14: 16,350 photos scanned, 8653 photos left when I quit
2016-12-26 00:49: 16,352 photos scanned, 8663 photos left when I quit
2016-12-26 19:46: 16,372 photos scanned, 8642 photos left when I quit
2016-12-27 18:29: 16,475 photos scanned, 8574 photos left when I quit
2016-12-28 23:43: 16,707 photos scanned, 8356 photos left when I quit
2016-12-28 23:43: 16,910 photos scanned, 8156 photos left when I quit
2016-12-29 23:51: 17,736 photos scanned, 7332 photos left when I quit
2016-12-29 23:51: 17,736 photos scanned, 7332 photos left when I quit
2016-12-30 ??:??: 17,933 photos scanned, 7141 photos left when I quit
2016-12-31 17:34: 18,025 photos scanned, 7064 photos left when I quit
2017-01-01 15:02: 18,307 photos scanned, 6782 photos left when I quit
2017-01-01 15:02: 18,307 photos scanned, 6782 photos left when I quit
So there was a burst of speed where it was doing 3,000 photos per day (still not fast, but eventually will finish at that rate), then it slowed to a crawl.
I’ve tried rebooting. I’ve tried leaving Photos running, and I’ve tried quitting. Nothing seems to make much difference. Anybody have this problem and solve it?
