I needed a way to transfer files and folders from one mac to another mac, but I wanted a fast connection. Naturally at first, I connected the two machines with an ethernet cable and turned on File Sharing in System Preferences. The performance - slow, very slow, 9.2 gig in 2 hours type slow. Where is the base 1000T??? So I Googled around a little and found that if you establish the network link (and hence a fat 1000T pipe) prior to file sharing you are setting the speed of the connection for the file transfers. But I could not find any place that had all the directions in one place, I had to piece it together, so here is a copy of my complete directions that are current for newer 2006 to 2010 Macs.
This only works with crossover cable, glad I got that cable now!
Alright, here we go:
\t* Connect both Macs, using a crossover network cable (using a normal cable showed ethernet not connected, in Network preferences)
\t* Open up System Preferences > Network
\t* Choose Ethernet, and select configure Manually instead of Using DHCP. If you open Advanced you will see connection speed, more on that later.
\t* Set the IP address to 192.168.0.1, Subnet Mask to 255.255.255.0
\t* Same as above, IP address 192.168.0.2
\t* If you go back and check the connection speed it should auto config to 1000T on both machines.
Both Mac #1 and Mac #2: Go into System preferences --> Sharing, select file sharing so the machines can see each other, now that the pipe is established and the speed has been set.
You should see the other Mac in the Finder sidebar, on either machine.
Use the Public folder on each Mac to share files and folders.
Dropping files/folders into User --> public folder, then on the receiving machine drag to new location.
A 9.2 gig transfer in less than 5 minutes, now that really is cooking with base 1000T ethernet!!!
