Whoa, this is some pretty heavy stuff ;) Try rather this:
http://developer.apple.com/samplecode/Sample_Code/Networking/GetMACAddressSa
mple.htm
http://developer.apple.com/samplecode/Sample_Code/Networking/GetPrimaryMACAd
dress.htm
More specifically:
http://developer.apple.com/samplecode/Sample_Code/Networking/GetPrimaryMACAd
dress/GetPrimaryMACAddress.c.htm
Once you've removed all the comments, it should be way shorter and it'll
teach you a bit of the IOKit ;)
