Hi Warwick, thanks.
1) When NAS appeared under Shared, it was connected automatically as GUEST. I then dragged internal files from Mac to a Public folder in my NAS. Initially, I dragged and dropped out of the public folder and message came out saying I need to click authenticate (but i didn't know where to click).
2) No error came out in the Finder.
3) Console messages... Any hope? 🙂
