Is it possible to copy a running Macbook's state (running Sierra) over to a new Macbook?
I can't use target disk mode for two reasons: one, I don't have a Firewire cable and am not sure where to get one on my tiny island; two, the old Macbook is broken: when restarted, it usually won't boot, and I fear it won't boot even into target disk mode. (At the moment, I'm keeping it running until the replacement arrives. Day five so far.)
There is a Time Machine backup, but I'm excluding a lot of non-essential files from it. If I added all those files just to transfer everything over, it'd enlarge the overall backup size forever, which I'd like to avoid.
