I migrated my rather large Photos library from El Capitan to High Sierra probably around 2-3 months ago. To this day, the Photos app still reports that it hasn't completed its analysis of all the faces.

I am aware that leaving the Photos.app open will pause its analysis so I have left it closed most of the time. As well, I have tracked the CPU time that the process is consuming so I do know that it is doing something.

Is there a way to kick the process into a more aggressive mode? I mean, why does it have to do everything so tenderly in background mode? It is almost like it is trying not to use my disk or CPU at all and quite frankly I've got a desktop with 8 cores, plenty of RAM and such and I wouldn't mind if it burned my CPU for 2-3 days to just get it all done.

To clarify: this is not a matter of a low priority or lack of CPU/RAM as the machine has plenty to spare and is left alone most of the time not doing anything. It is a question of if there is a config/setting that can tell the process to work hard on the problem rather than VERY passively?

Any ideas?

  • I'm also interested in this. I moved to a mac about a year ago and then an iphone a few months ago, and have yet to see any of the faces in my photos be identified. I've been considering downloading all of my old photos and seeing if that helps the face recognition figure things out but would like to avoid that. – BooleanCheese Aug 14 '18 at 17:37
