macos big sur 11.6
In Apple Menu > System Preferences > iCloud > iCloud Drive > Options (button),
please check Hook
Actually, in Big Sur it seems to be: System Preferences > Apple ID > iCloud Drive … etc.
it was checked before this happen, 3.2 do not have this problem
In Finder->iCloud Drive, can you see Hook->sync folder?
Also, if it is possible, could you please open /Applications/Utilities/Console, on the top right corner, enter “hook” in search field, then try to activate iCloud sync in Hook. After you see the Alert window which says “iCloud Drive does not appear to be enabled…”, select all output in Console window, copy and paste in an empty document and save the document. Please send the output file to firstname.lastname@example.org.
that’s good news. Did you do something that might have led to the change, or it just started working?
nothing special, no restart os, restart hook etc
