Have you done the basic research to understand how user account ID/passwords work on a MAC, or, a BSD variant? Once you have, I think the path will be apparent.

I could come straight out with the answer, but, knowing the answer without knowing how isn't of much value.  

Thanx sgware, I will search user account ID and password subject first. Also the file system, too.

I am googling.  

Most Macs have a DMA-capable Firewire or Thunderbolt port. Although there are exceptions, I would think this resource would work for the cost of a cable and maybe the adapter:

Woow this is great thing.

I like it. Thank you very much. That is the way I follow.
