Photos app on Mac does not update via iCloud Photo Library

Photos app on Mac does not update photos

For a few days now I've been fighting with my Photos app on the Mac (no, not because of Catalina, but still under macOS Mojave!). Why? Because it stiffly claims it would "update" but it doesn't.

I use the iCloud Photo Library and actually enjoy the fast syncing that brings photos I took with the iPhone to my Mac and iPad in seconds.

Unfortunately, exactly this "transferring" into the photo app on the Mac has not worked properly for several days. While the Photos app says it is being updated at the bottom, nothing happens for hours.

If the Photos app on the Mac no longer wants to receive photos from the iCloud, this tip might help.

Solutions to different problems

Now, this problem can be caused by several causes, ranging from incorrect settings to unreadable files in the photo library. The recommendations range from repairing the photo library (hold down CMD and ALT when starting the Photos app) to restarting the iPhone and Mac.

For me, it was ultimately a different approach that helped. I think my hard drive was causing the sync to stop working. I've moved the photo library to an external hard drive and the Photos app is usually open for me all day long. So far so good.

I suppose it was because my hard drive lost connectivity at night while the Photos app was running.

Uncleanly removed hard drive causes sync problems

Now I got to my Mac this morning and it said in the top right corner that the photos app had to be closed because the photo library was no longer accessible or damaged.

The reason for the message was obviously that the external hard drive logged off for a short time last night. The background process, which is always looking for new photos in the iCloud on the Mac, does not seem to have coped with this and has quit its service without terminating or crashing.

In the meantime, I have restarted the Photos app several times, but this did not help, as the process also survived closing the Photos app. Correspondingly, this procedure did not bring any improvement for me either.

In the activity display, look for "Photos" or "Photos" (in the English system setup), then select the "Photos Agent" process and close it with the cross at the top left.

If you end the process with the X symbol, you will be asked again whether you really want this. This is confirmed with the "Exit" button.

Solution: Shoot photos agent manually

I finally found the successful solution to my problem in the forum of stackexchange.com. In it, a reader described that you have to end the "Photos Agent" background process and restart it in order to get it going again.

But my complete guide is this:

  1. Close the Photos app on the Mac
  2. Open Utilities> Activity Monitor
  3. look for the Photos Agent or Photos Agent process
  4. End the process with the "X" button
  5. Restart the Photos app on the Mac
  6. Open the Photos app on the iPhone
  7. Wait a few seconds - then the first photos should appear as placeholders in the Photos app on the Mac

In my case, even after restarting the "Photos Agent" process, no photos were synchronized. Only after I unlocked the iPhone and started the Photos app did the photos arrive on the Mac after a few seconds.

This is how it should look when the Photos Agent resumes its service and the first photos arrive on the Mac.

It may be a coincidence that this happened because the process was supposed to be running all the time in the background and sending the new photos to the cloud, but maybe it was important. That is why I would like to describe my exact procedure.

If you also have problems with the photo sync and iCloud, please leave a comment. Maybe we can find the solution together.

    Hi,
    My problem is that my photos are displayed in the photo app, but if I want to select a photo as a background image in the settings, the folders are displayed there with the cloud in front of them, but if I click on one of the folders it is empty . The photos do not appear in the CEWE Photo World either, only the empty folders.

    • Sir Apfelot says:

      The cloud actually says that the photos and folders in the cloud are in the iCloud. For me, he downloads it when I click on such a photo. Then it appears in original size photos. The sync may not work anymore. Have you ever restarted your Mac?

      • Steffi says:

        This only works in the photo app. But not in the settings. In the Cewe Fotowrlt I have now found that the pictures appear there when I click on them in the INDIVIDUAL photo app, but that cannot be the solution. I wanted to make a photo book with about 150 bikdetn. I can’t have to open them all one by one ????

        • Sir Apfelot says:

          Hello Steffi! Have a look in the Photos app under Settings. The option "Load originals onto this Mac" should be activated there. Then it loads all photos onto your Mac without clicking them. I assume you have "Optimize Mac Storage" enabled ...

  2. Steffi says:

    The option is already activated, that's why I'm so at a loss. The option is also activated on the iMac and it still doesn't work. My albums from iMac won't appear on MacBook either.

    • Sir Apfelot says:

      I'm a little overwhelmed by that. :( If you can still find out what it is, it would be great if you could mention it here in the comment. Thanks and I'll keep my fingers crossed!

      • Steffi says:

        I will continue to research and will contact you when I have found a solution ????

          Hi, maybe someone else is reading along here ...
          I also have my media library on an external SSD on the MacMini.
          Again and again the SSD disconnects at night and iCloud no longer syncs.
          So far it was enough to deactivate and activate Photos under iCloud in the system settings. It does not work. I can't find the above process in the activity display.
          Do you have any other ideas?

          • Jens Kleinholz says:

            Hello Erik! I had that a few months ago too. I assume that something has gotten a quirk due to the frequent break in synchronization. In any case, I had tried all of my tips and nothing worked. Looking in the activity display does not help either, because the process is running, but the synchronization does not work. My nuclear solution: I dragged the iCloud Photo Library out of the folder so that the Photos app had to recreate it. It took me a night to get everything back in sync, but I haven't had any problems since then.

    Hallo,
    had the same problem. What helped me was the approach on Apple's support site. Open the Photos app while holding down the Option key (old). See there, I have (for whatever reason) three media libraries. And it was set the "wrong" one. I have selected the one in which the system library was written in brackets. And suddenly everything was fine again.

  4. Stephane Burger says:

    I thank you! I had exactly the same problem, exactly what I wanted to read. Merci

    • Jens Kleinholz says:

      Hello Stephane! I've had that again for the past few weeks and nothing has helped. At some point I created a new photo library and re-synchronized all the data from the iCloud. My attitude is that the originals are in the cloud to save space.

      • Erik says:

        Hello Jens, thank you for your tip above (there I could no longer click on answer). You write that you have "pulled out" the media library. So just go to another folder so that it is no longer the system library, right? After the new sync you deleted it, didn't you?

        What irritates me with this solution. In the cloud, 94 GB are used for photos and videos, the library is 107 GB. I'm worried that something will be lost. Can you explain that to yourself or to me?

        • Jens Kleinholz says:

          Hello Erik! Such differences in the storage space display can arise due to the size of the hard disk. A high-capacity hard drive makes larger "blocks", which in turn results in small files that only need a fraction of a block, but ultimately occupy a whole block and thus take up more "space" than on a small hard drive which the blocks are smaller. I wouldn't worry about that because of the difference in memory requirements.

          And yes, I meant it the way you wrote it. Simply drag the media library somewhere else so that the photo app can no longer find it in the old location.

          • Erik says:

            Hi Jens,

            it worked. Everything restored and in sync. Still hope that this solution remains an exception.

            Regards,
            Erik

          • Jens Kleinholz says:

            So I've been quiet since then ... for several months. So you can have hope. : D

    Moin,
    First of all, thank you very much for your contribution, finally something other than "register again" or "make sure that all devices are connected to the same ID" - blah blah ... as if you were totally stupid ...
    Unfortunately, your tip didn't work for me ... I bought a brand new MacBook Pro and I have to say that so far I've only connected it to the Internet via an iPhone hotspot. Could it possibly have something to do with it? In any case, I didn't have such problems with my old MacBook Air ... everything else, i.e. music, documents, etc., it syncs without problems within 1-2 seconds.
    I'm slowly desperate 😅
    I will still forest a little through the network but I would still be very happy about possible help.
    Greetings from the Baltic coast

    • Jens Kleinholz says:

      Hello Marco! Have you tried a normal router? The Mac may not want to use the iPhone hotspot to sync photos because it wants to protect your mobile data. Even when the iPhone is in sleep mode, it will not upload photos to the cloud. You really have to look at what is causing the hangover here. LG, Jens

  6. Marco says:

    All right, you're right 😄
    Today I took my Mac to work because at home it still takes a while until I finally have wifi again ...
    And joar worked 😁
    Actually nice and stupid of me but probably ne nice randinfo for everyone else. ^^
    Thanks again ✌️

    • Jens Kleinholz says:

      Hello Marco! Well, the main thing is that we have found the cause. It's not stupid of you. : D In any case, thanks for the feedback.
