iCloud Drive not uploading and downloading
My iMac and MBP are both running MacOS 10.12.3. I store all my files on iCloud Drive, from where they synch with my iMac (used to access the files routinely), MBP (used to access the files routinely) and iPhone (used to access the files infrequently). Until yesterday, any file (mostly Word, Excel and PDF format) copied to, deleted from or modified in the iCloud Drive folders on any of these devices has reliably synched via the iCloud. Yesterday this has stopped and all I get is a window that looks like this:
The symptoms are:
- Existing files in the iCloud Drive folder in Finder do not synch to iCloud Drive after changes are saved to them.
- New files copied to the iCloud Drive folder in Finder do not upload to iCloud Drive.
- When I delete a file in the iCloud Drive folder in Finder, iCloud Drive will recognise this and delete the file.
- I can upload files to the iCloud Drive via the Safari interface. Finder will recognise this and attempt to download the files, but never complete the operation.
- These symptoms are valid for all two desktop devices. I can access files stored on the iCloud Drive via the iPhone.
