Thank you, this solved the problem of iCloud not syncing or being stuck with cloud icon next to some folders/files. I give below all the correct steps (the terminal command you suggested is not 100% correct, there is a typo): Go to ~/Library/Application Support/ Delete the folder 'CloudDocs' Open Terminal and type killall bird Boom, problem solved: iCloud corrupted cache is gone and files/folder start syncing from scratch and every cloud icon next to folders / files is gone!
