How can I clear pending iCloud Downloads? So macOs just lied to me. I went into storage and recommendations. 
And saw this 



Which clearly says store all files photos and messages in iCloud and save space on Mac automatically when it's needed.

As soon as I accepted this recommendation what it actually did is this 



Which reads quite the opposite "The full contents of iCloud drive will be stored on this mac" ?!?!?! 

I managed to turn it off but now I have these massive downloads pending and not doing anything. 



How do I remove them?
From this article:

Click the Apple icon in the upper left corner of your Mac's screen.
Click System Preferences in the drop down menu.
Click on iCloud.
Click on Options next to iCloud Drive.
Click to uncheck the checkbox for Desktop &amp; Documents Folders.

Alternatively, try signing out of iCloud.
