Photos Agent using up CPU

You can Safely End process but as soon as you wake from sleep of re-boot it will continue until the new Photo app successfully merges with the iPhoto Library. It took about two hours of general usage for the high CPU to calm down for me...I thought my Mac was going to melt...😉

I have the same issue after the 10.10.3 upgrade.

Only in my case, my photo library resides on an external drive. My local iPhoto library is empty - I keep my actual iPhoto Library on an external drive. When I started the new Photos, it used my (empty) local iPhoto library - which apparently in converted into a "Photo Library" - and is still empty.

Nevertheless, the Photos Agent process is running and sucking up all my CPU. Doing what ? I have no idea.

I killed it several times, but it comes back up again and keeps on using CPU. Doing nothing. On an empty photo library. Go figure.

Please open the iCloud preference pane and uncheck the box marked Photos, if it's checked. Any difference?

Here's what I did: I opened Activity Monitor, then I clicked on the Energy tab and clicked on the little arrow next to the Photos Agent process that was obviously at the very top, with an Avg Energy Impact of 76.11 to reveal all the grouped processes that were running and forced them all to quit, one by one. My mac is now running as silent as a purring cat 🙂

They'll eventually start back up again.

They have work to do. When that work is done, the activity and CPU usage will drop.

they should really allow the user to manage that process. it crushed my MBP battery last night in under 2 hrs of intense CPU time while i was trying to get some actual work done away from a power outlet.

it's been a few days of intermittent use. thought it would have finished up by now.

My Macbook Air has been running red hot for days now. Constant fan use. The Photos Agent is buzzing like mad since Photos came along. I try to kill the processes but they come back instantly. What should I do? Apple really messed this up.

Not only does the Photo Agent slow down my Late 2013 Mac but it also brought down our internet.

I consider out internet speed to be reasonable (16.75 Mbps down and 3.29 Mbps up). But once I installed 10.10.3 and set up the iCloud sync my daughter came out of her room and asked what happened to our internet speed. What's more after an initial burst of photos (I saw them show up in Photos on my phone) photo upload speed slowed to a crawl. We endured for a couple days with few photos actually uploading. I called my ISP and they swear they do NOT throttle. Finally i shut off iCloud syncing and everything returned to normal.

I copied my photo library to a external drive and took it to work. Photo Agent didn't effect the speed of my Early 2014 Mac Pro and it took about 2 days to fully upload my 250GB of photos and movies (work isn't exactly T1 speeds but it's fasted than my home network).

I'm surprised the make isn't as transparent about uploading and downloading photos as my 6 Pus iPhone is. My phone received most of the photos without effecting battery life appreciatively.

I still want to bring my home Photo library in parody so I plan to run iCloud sync only at night for the foreseeable future.

Same problem... can't figure out how to get Photo Agent under control. Repeatedly kill the process since it is maxing out my limited internet connection on the road and I need the connection for work, not an uncontrolled app.

In a similar vein, Photos is missing multiple keyboard shortcuts and seems like the work flow of editing photos wasn't thought out. If you haven't updated yet, don't.

Once I got all my photos uploaded into iCloud at my work I started with an empty photos file at home and downloaded all my photos from the cloud. It took a day and a half to download 250 Gb of photos with my network crushed. But once it was done, Photo Agent calmed down and everything went back to normal. Downloading only went a lot fasted than allowing it to put photos in parity.

But why Photo Agent brings the network to it's knees when Dropbox can download a million photos quietly in the background is beyond me.

Very high cpu, fans spinning, etc. Still nowhere near done uploading 12K pictures to iCloud and been about 10 days now. Here are some shots from Activity Monitor:

and...

...

Yes, we're experiencing the same thing. Photos Agent is saturating my upload and killing my internet connection as well. I thought my wireless was getting hacked until I started analyzing the traffic with my router and then found the culprit with Activity Monitor.

This has to be a bug. I have "ICloud Photo Library" completely disabled under the app preferences, but if I disable it under ICloud system preferences the problem goes away. Only seems to start after importing new photos.

Getting irritated with the Photos experience and I'm starting to wonder if I should just go back to IPhoto.

What was the fix of this

my new mac pro showed up today from apple and photos agent is eating 100% cpu time
