macOS: Photos Won’t Sync Photo Stream [Solved]

photo stream wont sync photos app troubleshooting fix

Not getting your latest Photo Stream pictures in Photos from your iPhone? Here’s your solution!

One of the handiest features of the Photos app (which replaced iPhoto in 2015) is its ability to automatically sync with your Photo Stream. As long as you have Photo Stream sharing enabled on your iPhone, you never have to plug in your phone to your computer in order to import your pictures to Photos.

I just bought my wife a new/old Macbook Air last Christmas. And in spite of enabling My Photo Stream in Photos > Preferences > iCloud, her Photo Stream pictures just weren’t showing up in Photos.

It had everything up until January, which made me think it was working, but Photos was out of date. It turns out; it wasn’t working at all. The fix was quick, but sort of frustrating (what happened to “it just works,” Apple?).

To “unstick” Photo Stream in Photos, here’s what I did:

  1. Close the Photos app by right-clicking it and hitting Quit.

  2. Launch Activity Monitor. You can find this under Applications > Utilities. Or you can hit <COMMAND> + <SPACE> and type in Activity Monitor.

  3. In the top-right, search for “photos.”
  4. Look for Photos Agent. Select it and click the X in the top-left to force quit it.

  5. Re-launch Photos and see if it worked.
  6. If not, close Photos, go back to Activity Monitor and force quit the two processes that start with “com.apple.photos…” and the one that starts with “com.apple.CloudPhotos…” Launch photos and try again.

    I have a closely related problem

    If I do one photo at a time, no issues with any of my 3 devices syncing the pictures on photo stream.

    but….

    I have a new DSLR and recently began importing larger jpeg photos and more of them at once. Can be 200 photos each averaging 25mb. For a while, it seems the syncing worked, then I noticed that I was not getting these photos, when I download to upload to photostream.

    Recently, I noticed that I have to ensure photos stays open and the mac stays on until the upload is complete. If I close photos, or the computer sleeps, the upload stops.

    This would not be an issue for me if it simply restarted when I opened it back up (hey – I’m a busy guy. Sometimes I just want to clear the SD cards and get back out), but it does not. Once the upload quits, I cannot find a way to get it to restart.

    Kind of a pain-in-the A## to have to keep the app open and computer on, as these larger files can take a long time to upload.

    Any suggestions on a setting change that will make it restart and push out anything not already pushed out previously?

    thanks

    That worked for me as well, thank you.
    I have been restarting to solve previously.
    It’s really annoying Apple can’t solve this.
