Connecting via USB on Mac OS X

If you have not already, make sure you have followed the instructions in Getting Started Step 4.

1. On your Mac, open up System Preferences and select Network.

   

2. Once you get the Network dialog, click on the + icon in the lower left area to add a new network device. You'll need to select the CDC Composite Gadget in the drop down box. The name will be similar to what is shown below. I have renamed the service "ev3dev" so it's easier to keep track of later. Click Create when you are done.

   

3. Click Apply to save your changes. After a short time, \tThe ev3dev entry (or whatever you named it) should show connected and have a Self-Assigned IP address

   

4. Now, we need to share our internet connection with the EV3. Go back to System Preferences and select Sharing.

   

   Click Internet Connection on the left, but don't check the box yet. On the right, Share your connection from: will be Wi-Fi (or Ethernet if you have a wired connection). Also check the box next to CDC Composite Gadget

   

   Now check the box next to Internet Connection on the left to enable it. Read the warning and then click Start.

   

5. Next, we need to find the IP address that was assigned to the EV3. You can do this in Console and filter for bootpd, but since we are going to be using the terminal in a moment anyway, we will just show you how to do it there.

    host:~ user$ cat /var/log/system.log | grep bootpd
    Mar 27 16:50:12 host.domain bootpd[27463]: server name host.domain
    Mar 27 16:50:12 host.domain bootpd[27463]: interface en0: ip 192.168.0.100 mask 255.255.255.0
    Mar 27 16:50:12 host.domain bootpd[27463]: interface bridge100: ip 192.168.2.1 mask 255.255.255.0
    Mar 27 16:50:12 host.domain bootpd[27463]: DHCP REQUEST [bridge100]: 1,66:11:22:33:44:55 <ev3dev>
    Mar 27 16:50:12 host.domain bootpd[27463]: ACK sent ev3dev 192.168.2.2 pktsize 300
   

   The line with ACK has the IP address that was assigned to the EV3. 1921.68.2.2 in this case.

6. For ssh access to the EV3 under OS X, you can use the good old ssh program from the terminal window. I'm sure there are other solutions, and if you send me your suggestions I'll add them to a list.

   In a terminal, run the following command. Replace 192.168.2.2 with the IP address you found in the system log.

    host:~ user$ ssh root@192.168.2.2
   

   If you have never connected before, you will prompted to confirm the authenticity of the host, so type yes when prompted.

    The authenticity of host '192.168.3.1 (192.168.3.1)' can't be established.
    RSA key fingerprint is xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx.
    Are you sure you want to continue connecting (yes/no)? yes
    Warning: Permanently added '192.168.3.1' (RSA) to the list of known hosts.
   

   The default root password is r00tme.

    root@192.168.3.1's password:
