iCloud photo library not uploading

Photos > Preferences > iCloud. Try pausing the upload, then some time later resume it again and see if this helps. Re-launch Photos and re-start your Mac, as well.

The progress indicator is useless, do you know what the minimum possible time your library will take to upload is?

Tell me how big (in GB) your library is and how fast your upload speed is (in Mb/s, or even Kb/s if it is really slow)

Then I will tell you the minimum possible time.

Log into iCloud.com under the account in question and then pick the Photos app and see if you get the error shown below. My photos stopped uploading and it was because of this issue. I've sent the error report to Apple two days ago and haven't heard anything.They're other people having the same issues. Good luck! Scott

What worked for me was to completely log out of iCloud in my Mac->System Preferences, restart the computer, and then log back in to iCloud. I was stuck uploading 15,000 + items for two weeks with it killing my Internet connection. Once I did this, I was able to upload all items in two nights (I paused the upload from Photos->Preferences during the day to not interfere with my Internet access. Also, you should not that the number updating doesn't count down. It changes in batches. But, it should change from time-to-time if the upload is proceeding. After the first night of successful uploading, this number dropped from 15000 plus to 5000.

Thanks Stephen!! Were you also getting the error message (like I mentioned above) in iCloud.com before you logged out of iCloud on your Mac?

I'm not sure because I didn't check my online photos until after they had all uploaded. It took a long time for the number at the bottom of the online webpage to reflect the number of photos in the Photos' app, however. The photos were appearing on my devices as the upload proceeded.

The logging out and back into iCloud account seems to have worked for me. It is once again doing uploads. I did get the warning message about deleting all iCloud data from my iMac, but I proceeded anyway and that seem to be okay also. When I logged back into iCloud everything was again available.

I just hope the uploading does not stop again.

Logging out of iCloud and logging back in didnt solve my issues - just caused problems ... 67,000 duplicate photos :-(

Wow how long did it take to upload 134,000 photos to get 67,000 duplicates. How much iCloud storage did you need for a library that size?

Took 15 days to upload 39,000 photos. Now the issue is that all the photos are on my computer and on my Iphone. I deleted a few pictures from the phone to see if they would not be deleted on the computer but they were. It stated that deleting the photos would delete on all devices. I did not think the computer was considered a device. How can I delete photos from my phone, yet keep on computer?

To prevent doing something irreparable, please learn more about how Photos and iCloud Photo Library work together to make all images "available" on all your devices.
