We have had this problem for a long time. Well before 2.7.6. If nothing
is connected to the internal ethernet port then opening the port will
cause a system wide hang for several seconds.

We have not been able to determine what the problem is or why it occurs
and Apple has not answered any questions regarding this problem.

This happens to the built-in port if there is no connection - for
the built-in port, accessing the NameRegistry/IORegistry will be a
faster way to do this. For Mac OS 9, the GetEnetAddressDirect
sample demonstrates the use of the NameRegistry to get the address
for the built-in port.

For Mac OS X the GetMACAddress sample shows how to get the Ethernet address:
