I recently got a refurbished 2109 27" iMac (I love it!) and decided to do a fresh installation of everything, rather than migrate from my 2012 i7 Mac mini. For backups, I use a combination of iCloud, Time Machine, and Carbon Copy Cloner. Because I figured that copying the contents of my large Documents folder from an external SSD clone of my mini would be faster than downloading the files from iCloud, I opted not to turn on iCloud until my iMac was fully set up. When I turned on iCloud, I learned that my Documents folder was on my local drive and therefore presumably not synced to iCloud. So I dragged Documents to iCloud Drive in Finder, and suddenly everything had the cloud-with-the-down-arrow icon next to it. Apparently, I needed to download everything to maintain synchronization. I started clicking on the cloud icons at top-level folders, and the contents were downloading fine, as indicated by the circle with the progress indicator, after which the cloud icon disappeared. At some point, though, this stopped working. For the remaining folders or individual files, clicking on the cloud icon does nothing. If I double-click on a document to open it, though, the document downloads. If I create a new document, it automatically uploads to iCloud, so the connection is still there. I don't want to have to open all of my remaining documents just to download local copies. I have a 2TB Fusion drive, of which I've used 750GB, so it's not a space issue. The reason I want local copies is to have them on my CCC bootable clone. Any ideas? For whatever it's worth, I gave my i7 Mac mini to my wife as a replacement for her slower 2012 i5 mini, and I performed the same type of fresh installation. I was able to download all of her Documents folders and files from iCloud with no problem, although she has far fewer files than I do.
