photoanalysisd taking large amounts of cpu

After upgrade to OS X Sierra - I'm assuming it's doing something to my photos....



Any thoughts?

MacBook Pro, Mac OS X (10.7)

I've got an older (late 2009) iMac, and after 6 hours, only 1500 of 18,000 photos have been scanned. Apple ought to give the user an option (1) to reduce the priority of the photoanalysisd task, (2) forget People analysis (I don't use it -- perhaps this new analysis will improve its accuracy and recall, but Faces in iPhoto was laughable, making way too many errors of omission or commission) or at least allow the user to turn it off so a rational backup can be completed, (3) schedule it for off-hours, or all of the above.

Hello i_cola ...

The link you gave for Lightroom import of pictures is only for iPhoto and Aperture, not the Photos app on the Mac. To import the Photos library on the Mac, you have to first use Finder to create an "alias" file for the actual Photos Library, then import that "alias" instead. It will then import both the original pics and videos, and the .jpg for any that you may have edited. Good luck!

Very similar experience for me as well. Mid-2011 MacBook Air. 25,000 photos and 2 weeks of screaming fan and slow motion desktop, and only 15,000 photos have been processed so far, and 10,000 to go. All of them have already been processed on my late 2013 MBA as well. No way to turn it off. Yes this particular machine is old, but no it's not okay to force this on us.

You can get a rough idea of timing by clicking on People, looking at the number of photos already processed, the number of photos remaining, and the amount of time the computer was on since Sierra was installed.


You can pause it by opening Photos (somewhat counterintuitive) or disconnecting from the power supply (which made me laugh since I'm on a desktop Mac). You may be able to stop the process in Activity Monitor. I haven't tried it.

Thank you for the link....I just sent my feedback as well. I have 35,000 photos, and my MacPro (mid 2012) has been nearly unusable for two weeks. Sometimes the entire system just grinds to a halt and a restart is needed. All of this has happened since Sierra installation. It's maddening and my workflow has been hampered seriously to the point of tossing the computer and considering another brand.

I have this same problem. I updated to Sierra today and all of a sudden my MacBook Pro is running very slowly. I go to activity monitor to see that "photoanalysisd" is taking upwards of 140% of my cpu. Come on apple, I at least expect a pop-up telling me that it will run the photoanalysis in the background. Or maybe this can run when my MacBook is not in use?

Fix this please.

Thanks
