Help with turning on iCloud I use an iMac running macos High Sierra. I was trying to do something with my Documents folder and I turned off iCloud on my "Desktop and Documents" by unchecking the box in the System Preferences/icloud/option window as shown below.



Once I finished I wanted to turn iCloud back on by clicking the above checkbox. However, it will not turn back on. When I click on the checkbox the checkmark appears as shown below and a message saying "Setting Up..." appears.

But if I close System Preferences and then reopen them, the checkmark is gone. Can someone tell me how to turn iCloud on for "Desktop and Documents"
Here's a description of what happens when you turn off Desktop &amp; Documents folder. It might simplify things to move all the stuff that went into the Desktop and Documents folder that was created into the default Desktop folder or Documents folder (or distribute the items between those two folders), then delete the new Desktop and Documents folder to make things the way they were before the option was enabled originally. Then I would suggest logging out and back in before attempting to enable Desktop &amp; Documents folders in iCloud prefpane again.
