problem syncing photos with icloud

Hi

First check that the library is set as the system library - the circled button should be greyed out. (Photos preferences) If it isn’t, click it.

Then check icloud settings are as shown.

Also make sure you have enough iCloud space for your whole library, and lots of free space on your mac and phone.

Give this a try: boot into Safe Mode according to How to use safe mode on your Mac and test to see if the problem persists. Reboot normally and test again.

NOTE: Safe Mode boot can take up to 3 - 5 minutes as it's doing the following; 

• Verifies your startup disk and attempts to repair directory issues, if needed

• Loads only required kernel extensions (prevents 3rd party kernel/extensions from loading)

• Prevents Startup Items and Login Items from opening automatically

• Disables user-installed fonts 

• Deletes font caches, kernel cache, and other system cache files

Good news - thanks for letting us know.
