Migration Assistant forever looking for other computers I want to use Migration Assistant to transfer data between two macbook pros, both on OS X 10.9.2.

I have them connected via thunderbolt ethernet adapters.  

When I go into migration assistant on the target, I can see and select the source and I see a code.  The source says on the "Migrate to another Mac" screen "Looking for other computers" forever.  

I've ensured that the firewall is off on the source, and that the sharing settings look the same.  

What else can I check/try to get this working?
I solved the problem by configuring on both macs IPV6 to automatic (one has "disabled", the other "automatic"). 

Hope it will help everybody in the future.
