error 36, badly. iCloud drive was problematic.
not a question, more of an experience i just had for days, and found a solution by miscela, hope it helps.
i was not able to copy any folder from the startup drive if the folder was inside icloud drive, to the same drive or to external drives. i can copy files, but not folders.
folder copy was working from external drive to the startup one, and also from other directories, for example from application folders to desktop (icloud).
the error said that the finder cannot complete the operation because some data in “” cannot be read or written, not showing the folder name. the issue was definitely related to icloud, so i entirely disabled icloud drive and re-enabled it. problem solved, no more error 36.
dot_clean did nothing.
