His prepper videos ? What ' s that ? <| sep |> It ' s a pretty funny joke , just the format isn ' t . Find a different format and it would be amazing . <| sep |> Hard disk is probably fastest if you don ' t have Ethernet , but here ' s how to do it over the network . Go in to System Preferences , and enable Sharing File Sharing on the destination machine . You will need to specify at least one folder that you are sharing , and who gets readwrite access to it . Now if you have an Ethernet port , plug an Ethernet cable directly between the two . Unfortunately I think this was another thing that was Ived away , but it is a lot faster than using WiFi . If only one of your machines has an Ethernet port , it ' s still worth connecting that to a port on your router . WiFi only will work , but slowly . Go in to Finder on the nonsharing machine . Press CmdUp until you see Network in the Finder window . Doubleclick on that and you should see the other machine . At the top right of the window you will see a button saying something like Connect As . . Click on that , and it will ask for login credentials . After that the target file system should show in Finder and you can copy files over as normal .
