Internet Sharing not working with my BeagleBone Black Running Mavericks on a 15" MBP. I have a BeagleBone Black running Debian Wheezy. I have connected the two with an ethernet cable. I have a working wifi connection from the MBP. So I turn on Internet Sharing to "share my connection from WiFi to computers using ethernet".

When I run ifup eth0 on the BeagleBone Black, I see the following output:

Watching the output from Console on my MBP though, I can see it doing something

I don't know where to go from here. I do know that if I plug the BBB directly into my Netgear router, then it successfully fetches an IP address via DHCP. So I don't know if the problem is entirely on the Apple Internet Sharing side, but it's at least part of the problem, because the BBB, Just Works(tm) otherwise.
I'm on Debian Wheezy too and this worked for me:


Install Mac drivers from http://beagleboard.org/Getting%20Started
Connect BBB to Mac through USB
On the Mac, go to System Preferences > Sharing > Internet Sharing > Beaglebone Black
In System Preferences > Network, make sure BBB is in the left hand side and shows “Connected”
After SSH’ing into the BBB, run “dhclient” (or "dhclient usb0” if that doesn’t work) and then try “ping google.com”.
