photoanalysisd taking large amounts of cpu

Well, it doesn’t happen on my version of Photos v2.0, all I see are the faces/people i have names and a “+” sign to see all the 1000+ faces/People I have not identified. So I have no Idea how far along photoanalysisd is in the process.

Exactly.

Furthermore, even if we could tell it's progress, we should be able to disable it. It's nonsense, and it's a crappy user experience if you don't actually need it.

The fact that they didn't even think to throttle the process, shows how far Apple has fallen in the UX game.

Yes, I have let photoanalysisd run, I have not gone into terminal to stop the process ( really doesn’t make any difference, it restarts itself even when photos is not running or started), I currently have 1076 faces that have not been identified and it is growing, it was 950 two days ago, so seeing faces doesn’t mean photoanalysisd is done....

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

The new system protection will not allow that command to work. Here is what I did to kill that CPU hog.

1. Run from another system disk

2. Find /System/Library/LaunchAgents/com.apple.photoanalysisd.plist on the system disk with the problem

3. Drag that file to another folder, such as the desktop

4. Restart from normal system disk

5. To restore, reverse the procedure by putting file back where it was

"If you click on "people" in the left hand sidebar of the Photos app, it tells you how many photos it has processed, and how many are remaining."

No, it does not. All it shows are a few faces. No stats about how many are remaining to be processed.

I don't recall seeing anything in the Settings or Photos Preferences to disable this feature -- is there a way to turn it off?

It's normal for that process to take a long time. The amount of time is a function of the number of photographs in your Photos library.

Happened with me. Stopped after several hours. I assume it was reorganising/analysing the library somehow.

My informal testing suggest an estimate of approximately 1 hour per 1000 photographs, if you are not actively using the Mac during that time.

None that I have found. None reported so far that I can find. I've sent Apple some feedback.

26000 in 48 hours so far. So I'm in for a few more days of processing.

Thanks for the link, EricDu.

I'll send my feedback today.

Does anyone know if deleting the Photo app will stop this photoanalysisd nonsense?

Exactly - I don't use it, don't need it - but it's going to take another 10 hours. It was the same in iPhoto, why on earth can't you turn this off?

Totally Agree with you!
