I find in the log a File/Action ‘iCloud (CloudKit) message’ stating under Info “File X missing of database Y”. The exact same message repeats every minute (after automatic syncing) (same file X, same database Y). The file is unknown to me, with a weird .manifest extension (long hexadecimal.manifest name). The same message shows on different computers syncing to the same database.
Right-clicking the log line only shows a dimmed pop-up menu.
Neiter Verify & Repair, Optimize, and Rebuild solves the issue.
The file is not present in the ‘Orphaned files’ folder.
I cannot find that file via the Finder.
Any other suggestion?
