Are you using JDK 7 on the mac? If so can you try with JDK 6?
I have seen some NIO issues with Mac JDK 7, not sure if this is what you are running into.
We have had probvlems to start JBOSS-7 at all using JDK1.7.0_04, but thanks to https://community.jboss.org/people/ctomc we tried with JDK 1.6.
Now the applserver starts faster, but the naming exception remains.
