photoanalysisd taking large amounts of cpu

This command in Terminal should quite photoanalysisd task and prevent it from appearing in future:

launchctl unload -w /System/Library/LaunchAgents/com.apple.photoanalysisd.plist

To re-enable photoanalysisd:

launchctl load -w /System/Library/LaunchAgents/com.apple.photoanalysisd.plist

I followed this response from another person in this discussion and it seems to have worked. My MacBook Pro

no longer heats and it do not find photoanalysisd listed on my computer. Judy Lundberg

Just did another test with only Photos and Activity monitor open. When I click on Photos to bring it to the front, the process drops to 0.5% within 10 seconds. When I click on the Finder, the process ramps back up to 150% within 20-30 seconds.

So it's not enough to keep Photos open. You have to keep it in the foreground too. In other words, Photos is in control of your computer whether it's on or now.

Your recollection is flawed. Excerpted from Faces overview:

"When you open iPhoto ’11, iPhoto automatically scans your photo library and groups likely matches."

Nevertheless, if you don't like Photos, then don't use it. There are many other photo-organizing apps from which to choose.

I understand. All you or anyone else can do is to make your displeasure known to Apple, here: Feedback - macOS - Apple. I have reason to believe they lend serious consideration to thoughtful suggestions. Your Feedback won't be the only one, so make it stand out.

Same situation on my Mac,i am using Serato Dj and my cpu is going wild,whats’ wrong Apple....? Return to P.C....? :(

I think this is just the new normal with Apple. Planned obsolescence, horrible UI, no UAT or QA, and we just have to suffer through it if we want to use their products.

We are now into a 3rd day. There should have been an option to disable the feature.

How/where do I put this command to make it stop?

Let’s all just bend over and give them more cash. NOT!

I've had the same issue. I tried force quitting and it came right back. It's a new process for organizing photos via Sierra. Because it's taking so long I think it's a bug. Just my humble opinion.

Curious -- Where do you guys see how far it's gone through its processing? Clicking people in the lefthand sidebar just shows me pictures, not sure what I'm missing, but it's probably something simple.

My experience is similar to that of ChristopherCurtis -- it took a few hours to complete the processing, meanwhile the CPU utilization was displayed at >100% on the activity monitor. Fan was running all-out during that time.

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!
