When you drag-drop files to the Trash or copy-paste files to your external drives, your Mac fails to do so and shows The operation can't be completed because an unexpected error occurred. (Error Code -1407). The 1407 error code can be caused by the following potential reasons.

  • Your macOS system locks the file. You'll find unable to move, copy, or remove a file from the system if it's locked. Mac error code 1047 will appear if you attempt to do so.
  • The file is being used by another program. For example, you won't be able to delete a Word document if it's still running behind. Or, Finder is using the file you want to delete or transfer.
  • Abrupt termination that results in a damaged file. When the Mac shuts down while you are working on the file, possibly, the file will get damaged and can't be deleted or transferred.
  • The file format is not supported by your connecting device. When you transfer files from your Mac to another storage device, check the file system compatibility.
