iMac Photos syncing or uploading
My iMac will not sync photos from iCloud. I have a 400 gb photos library and I pay iCloud for the updated storage. Everything was working great until about 3 months ago, when my iMac stopped updating photos that we taken on my iPhone. I have tried to uncheck the Photos checkbox in iCloud but now iMac gets stuck Uploading (currently at 17,369 items for the past 3 days). I don't want to restart this process again because I've done that so many times.
I've tried that unchecking Photos several times over the past 3 months; it never completes the upload. I also have tried creating a new Photos library per the Apple support document to ensure Photos is working correctly (it is).
Photos appears to be working correctly on my iPad and iPhone. I have a very fast internet connection, 280 upload, 800 download.
Anything else I can try?
