logged out/logged in/rebooted. Again.
Re-checked the box for Desktop/Documents in iCloud.
Re-checked the box for iCloud in iPhotos.
Documents are not downloading from iCloud.
Photos is āupdatingā. Again.
EDIT: Photos is now āuploadingā 4,562 items. No process name in Activity Monitor has sent more than 1.7MB of data. Bird has sent/received zero bytes.
follow-up: switched to Disk activity panel - bird has written over 7GB of data and the number is slowly climbing. Unsure why this isnāt registering in the Network panel, but at least something seems to be happening. Photos app shows a progress bar. iCloud Drive in Finder shows no progress indicator.
Think Iāll leave this overnight again and see if anything looks different in the A.M.
EDIT: photos are syncing, Documents are downloading. All is well!
Narrator voice: āAll was not, in fact, well!ā
Photos āuploadingā did not actually upload a single file overnight. Tried pausing and resuming this morning. Still nothing. So I tried repairing the library again. It then did the whole ārestoring from icloudā thing, and I watched theh library size grow back to ā¦ well, almost its original size. Photos still says it is restoring but nothing is changing anywhere.
As much as I hate splitting things up between two services, Iām fairly close to just chucking iCloud for anything but data that apps store there, put all my files in Google Drive and Google Photos and keep nothing in Apple Photos but the last 30 days of Photostream. Will have to have a big training session with the wife on making sure everything gets synced up and on how to find things. Simplification be damned!
What kind of Wi-Fi do you have? Iāve been relying on tethering to my iPhone when I need my Mac online and while iCloud synching works for most things it does not work for Photos uploading or downloading. So, if youāre using any kind of hotspot connection that shows up as the two interconnected circles instead of standard Wi-Fi bars in the menu bar that might be your issue.
I primarily use iCloud Drive for my business and personal purposes. I do have subscriptions to Google Workspace and Microsoft 365 and use their cloud services as well.
I just purchased a new M1 Pro MBP and noticed there is a difference in the initial iCloud Drive sync vs the other services. On Google Drive and OneDrive, I was able to see the folder / file structure very quickly, but it took several hours for sync to complete. On iCloud Drive I didnāt see ANYTHING for several hours, then everything populated at once, including the full file downloads and photos.
Please note that I am on a 1GB download speed, so my times would be less than yours.
TL;DRā¦have patience, it should work out OK
Iāve been trying the park WiFi and AT&T (my own hotspot) - now trying my iPhone tethering, since you mentioned it (Verizon plan is truly unlimited, no throttling). Photos is still stuck, or at least appears to be, but how would I know because APPLE DOES NOT WANT TO GIVE ME ANY INDICATION OF STATUS
If youāre tethering it definitely wonāt work. There is an actual limitation on tethering a Mac to the iPhone, a software limitation, that prohibits iCloud Photos updates, uploading/downloading on the Mac. I tried for several days before I finally went searching of a solution and discovered that it is a limitation of iOS.
I agree, Photos, IMO, is the most reliable service on iCloud. It does not, however, work with any predictability. In the meantime a few of these might come in handy.

Iāve had several variations of this experience and itās extremely frustrating, usually related to downloading originals or general āupdatingā notices that seem to go nowhere. I recently was stuck on downloading originals for two full days with zero movement.
Two things that help to get things moving, which might not have any impact on uploading but worth a shot:
Finally got tired of seeing ārestoring from iCloudā and turned it off, exported everything, downloaded Google Drive, added all documents and photos and videos, upgraded Google One to 2TB, initiated a transfer of all photos and videos from iCloud to Google Photos. Took about 30 minutes.
If it is any consolation, I think you will find search in Google Photos is much better.
It appears that you have entered the iCloud sync morass, compounded by signing out from, then back in to iCloud **. This is in addition to whatever issues you might have with your iCloud storage level and your internet bandwidth.
** Signing out then signing in to iCloud from a device in which photos are stored in full resolution results in the following: the iCloud service will check every single image to see if it has been synced to iCloud. This can be very slow with large photo libraries, and is much slower than simply downloading your iCloud Photos anew to an empty system library on your device. Even worse, during this image-by-image check process no new photos come down to the Mac.
I suspect that you may have encountered this situation. For more information and a blog post describing a clever work-around, see this previous MPU Forum post: https://talk.macpowerusers.com/t/tab-groups-in-safari-on-mac-not-showing-up-in-safari-iphone-ipad/25913/3
That would explain why thereās no network usage by photos yet if it is in the analysis phase
As opposed to Google Photos, which evidently checks one file, starts uploading it if needed, then proceeds to the next file, resulting in a steady stream of uploads even while still checking on file sync status.
Right now my files are uploading over my Verizon connection, tethered to my iPhone. Connection is showing 75down, 16up. Theoretically I have a 10GB limit per month of tethered data. Tonight I will test this limit. Tomorrow Iāll have a Spectrum cable modem to use for the week. Hopefully by the time we head out Iāll have everything in the cloud. Just not the i-Cloudā¦
It is not clear exactly what it happening from the information provided, but this iCloud-to-Google Photos transfer may not be the same process as that described in the original post. In the original post above, photos stored locally in full resolution had to be re-synced to iCloud after the userās iCloud sign-in was interrupted. As described previously, this re-sync is excruciatingly slow for large locally-stored system libraries.
The new transfer-to-Google Photos procedure appears to involve either one of these two processes: 1) first-time upload from local device to Google Photos, or 2) āCloud-to-cloudā transfer from iCloud Photos to Google Photos as described in this Apple Support article: https://support.apple.com/en-us/HT208514
Can you determine which of these two is actually occurring?
Maybe, and good to know if this is actually true. Is Google Photos actually checking a previously-synced locally-stored library, or is this a virgin upload to a new Google Photos library?
Google Photos is highly regarded by many users, but there are some limitations to be considered. I donāt know how Google Photos handles RAW files; there are reports that some usersā RAW files were compressed. Could be an isolated problem - itās not clear. Also, Googleās services are frequently changed (status of free storage and discontinued services are two examples).
I am constantly re-assessing the strategy for my permanent photo storage/backup solution, one that would be simple, hands-off and ājust workā. iCloud Photos has improved nicely in recent years, but there are some limitations and some situations to be avoided. One of these is this re-syncing a large, locally-stored-in-full-resolution library. Here is a link to a blog post with a creative work-around.
Google Photos might work as a second Cloud backup, but I am not yet ready to trust it as my primary storage and backup. @dixonge Please let us know in this forum how this works for you going forward.
I use Apple and Google but my primary photo storage remains terrestrial. 
Hereās some info on Google RAW I found. Not sure how helpful it may be:
Just gonna put this out thereā¦ does anyone know if iCloud Heaven even exists?
In your dreams 
FWIW, Cloud problems are not confined to Apple-iCloud. Even the famed Dropbox has its issues. There is, of course the infamous intrusive, bloated and resource-hungry Dropbox macOS app. And Dropbox also can be slow when syncing, as explained by @tjluoma in this post:
https://talk.macpowerusers.com/t/replace-dropbox-app-with-maestral/25701/4?u=arthur
excerpt:
Dropbox apparently overcomes slow or erratic sync by brute force (the aforementioned intrusive macOS app). Appleās iCloud sync simply putters along, oblivious to users but eventually completing its tasks. Most of the time.
I have learned ā¦ the slow and painful way ā¦ to bypass certain weaknesses of iCloud and Dropbox. Two examples:
There is no āmayā about it - there was nothing about transferring photos from iCloud to Google in the first post.
I donāt have to ādetermineā it - I know exactly what I did. It is the 2nd option you mentioned. I initiated this today, only after determining that I was not going to stay with iCloud.
It is uploading files from folders. No library involved. I already had a lot of photos there, as I previously was thinking of using Google Photos as my primary cloud. I am now resuming that process.
Regardless how things go in the future, the bottom line is that Google Drive and/or Photos just works. Out of all the pros/cons of each service, I never thought that taking days and days just to decide what to upload would be a problem with any modern cloud service. Since switching over 10-15 GB of files and photos have uploaded/downloaded. Thatās more than iCloud achieved in a week.
Evidently there is a promotion going on. My upgrade to the 2TB tier on Google One has caused them to send me a Google Nest (2nd Gen) device.
For free.
