I have about 110,000 photos and videos in my Photos library, synced to my Mac with iCloud with "download originals" turned on. Sync was working fine until a few days ago, about a week after installing Catalina.

I accidentally opened my Photos library from a networked Mac and closed it. It didn't appear to cause any problems, but the next time I opened Photos on the local Mac, it gave me a "repairing library" progress bar. That eventually completed and all my photos showed up. So far so good. But since then (five days ago), it has not downloaded any new photos from iCloud.

In "All Photos" view, at the bottom where it would normally say "Downloading x new items", instead it says "Restoring from iCloud...":

Restoring from iCloud...

The numbers are wrong. When I first open Photos for just a second it shows slightly lower numbers, which are the numbers of photos and videos actually in the library. Then the "restoring" message comes up and it switches to a higher number, which is still lower than the number shown on my phone and other iCloud synced libraries. The photos missing from this library show up fine on those devices.

The iMac has been on and attached to a fast and reliable internet connection the whole time. I assumed it would resolve on its own, but it has now been 9 days and it's getting inconvenient to not have access to new photos.

When I posted this I was running macOS 10.15.1. I have since upgraded to 10.15.2, and the problem persists.

I've tried restarting and I've tried turning "Download originals to my Mac" off and back on, to no avail.

Last night (day 8) I opened Photos while holding command-option to rebuild the library. It took about 9 hours, after which it went right back to the same "Restoring from iCloud..." message.

Has anybody else run into this problem? Anything I can do to get it back to normal syncing?

  • iCloud Photos can take quite a long time to sync your library. This is all dependent on the file size of the photos & videos, the time your Mac is awake and able to sync, and your internet connection. If you search here, you can dozens of similar questions. The only consistent answer is to wait, leave your computer awake, and try not to use it for anything else until the sync is complete.

  • @fsb I'm familiar with normal iCloud syncing. What I'm asking about here is the "Restoring from iCloud..." message specifically. If you can point me to other questions/answers that deal with that I would be grateful.

    Which OS are you running? After I upgraded to Catalina I had a host of iCloud and iCloud Photos related issues. My advice to you is, if you've upgraded to Catalina, don't change anything. We may still be a few minor version releases away from the OS being stable and practically usable for most people. I decided to disable iCloud Photos entirely which led to a series of subsequent and new issues.

  • @Harv I am indeed running Catalina, so that's probably it.

    Yup. I had the same issue, or at least identical symptoms. Apple's QA seems terrible these days.

Since I ran into the same issue, I had to research this as well. From what I found, this seems to be normal. After a library repair, each photo is being verified against the iCloud library copy.

This Apple support document 1 states:

If you repair a library that's automatically updated with iCloud Photos, the entire contents of the library re-updates with iCloud after the repair ...

Just like a normal iCloud library upload, this can take a very long time. For my 20.000 photos, it's currently at 72 hours without an indication of being finished any time soon it took about 80 hours. Then, the Photos app showed Updating (only the word Updating without any additional information) for a few hours before now switching to Uploading 19,800 items.

It's re-uploading every single photo in my library. Due to my low upload bandwidth, this is a very slow process and it uploaded about 1,000 photos in the previous 4 days.

So for me the messages that showed up in the status bar were, in order:

  1. Restoring from iCloud (for about 4 days)
  2. Updating (for a few hours)
  3. Uploading x items (very slow, will possibly take many weeks to finish)

UPDATE Jan/10: I took the laptop to work because we have a very fast upstream connection there. Over the weekend, it uploaded all photos, downloaded the new ones and is now back to its old Updated Just Now status.

    To make sure I understand: it started with the "Restoring from iCloud..." message, then after 80 hours switched to "Uploading x items", and counted down to zero? And it's now fully updated and syncing new images from iCloud?

  • Unfortunately no. I’ll clarify my answer shortly. From “Restoring from iCloud” it went to “Updating” (without any number or additional info) and stayed there for a few hours. Then it went to “Uploading x items” and it’s uploading the full library again - every single photo and video. Due to my pretty sad upload bandwidth, it has so far uploaded about 1000 images over the last 4 days. Commented Jan 6, 2020 at 11:13
  • @Robert I would be interested in the fate of your library! Commented Jan 21, 2020 at 18:09

    I gave up before the "Restoring" message went away. Turned iCloud off and back on, and it re-uploaded every photo very slowly. Now all good. Added an answer with slightly more detail. Thank you for your help!

    The crazy thing is I'm now having this problem and I did NOT do a repair. Really annoying as I want to add some descriptions and keywords and now I don't even see the photos and videos that I took earlier since earlier today but they should already be visible on the laptop. And yes Catalina.

Here is a way to figure out what's going on under the hood : use the Console app or the command line Log tool :

log stream --predicate 'process == "cloudd" or process == "cloudphotod"'
  • Maybe also or process == "photolibraryd"? (at least tested in Ventura, maybe the name has changed). Commented Nov 2, 2022 at 8:37
  • This fixed my problem. It was stuck on some networking errors (DNS). Changed network settings and now it is progressing again. Wish that the Photos App could show the logs... Commented May 13 at 7:05

My library is back to normal, but the question is still somewhat unanswered. After 12 days of "Restoring from iCloud..." I gave up hope and turned off iCloud Photos (both in the Preferences pane of Photos and in the system preferences under "Apps on this Mac using iCloud". One or the other told me that one unspecified item would be deleted, which in desperation I agreed to. Restarted and turned them both back on.

Photos thought for a while and then said "Uploading 11X,XXX photos". I left it open while it counted down agonizingly slowly for about a week. The first 50k took much longer than the rest, so maybe it does the bigger files (or more recent photos) first. When it finally got to zero, it downloaded the new photos that were missing, and everything has been working fine since.

If I get the "Restoring from iCloud..." message again, I'll probably skip right to turning iCloud off and back on, since it sounds like there's no way to avoid re-uploading every photo anyway. Of course if anyone has a better solution I would appreciate a real answer.

Update and warning:

When writing this answer I went back and turned off iCloud Photos in both places again, hoping to figure out which one triggered the re-upload. I was expecting it to give me a warning. THERE IS NO WARNING. Now my Photos app is back to "Uploading 11X,XXX" photos.


I've had the same issue. After some troubleshooting, I realised my Mac was running low on disk space. After cleaning up and making more free space, Photos app immediately started syncing iCloud photos and showing them in the app.


"I'll probably skip right to turning iCloud off and back on, since it sounds like there's no way to avoid re-uploading every photo anyway."

This is an old thread, but I'm wrestling with a similar problem on a brand new Sonoma iMac at the moment. I just wanted to point out that if you turn iCloud photos off and on and it appears to be re-uploading all the pictures, I think what it's actually doing is comparing the local copies to the cloud copies, not completely re-uploading them. We've been through this a couple of times and what I called the "inventory" step definitely goes faster than the actual original uploading did.
