I had to install new hard drive could not transfer files from old drive. Started new hard drive as a new Mac. Signed in Enabled iCloud Drive, and checked iCloud Drive desktop and documents option but after 12 hours the Desktop is empty, and so is the Documents folder.
If I check online, all my files are still there. But they are not showing on my computer, running macOS High Sierra.
I have tried signing out again. In iCloud settings, I have checked Desktop and Documnet Folders to check that it syncs.
How do I get the contents of Desktop and Documents to sync to my Mac?
