MAC Address of a Mac

Greetings,

I'm attempting to protect my home network by only allowing MAC addresses that I specify to get in.  One of the machines that will be on the network is an Apple Macintosh.  Where do I go to get that MAC address?

You can also use the System Profiler:

Apple -> About This Mac -> More Info...

Then under the network, you can check either Airport's Mac Address or Ethernet Mac Address...

open the terminal and issue
ifconfig en0
( for network card)
ifconfig en1
(for wireless n/w card)

Ex:KOSARAJUS:~ KOSARAJUS$ ifconfig en0
en0: flags=8863<UP,BROADCAST,SMART,RUNNING,SIMPLEX,MULTICAST> mtu 1500

        ether 00:19:f1:40:22:46(this is the mac address)
 
        media: autoselect status: inactive
        supported media: autoselect 10baseT/UTP <half-duplex> 10baseT/UTP <full-duplex> 10baseT/UTP <full-duplex,hw-loopback> 10baseT/UTP <full-duplex,flow-control> 100baseTX <half-duplex> 100baseTX <full-duplex> 100baseTX <full-duplex,hw-loopback> 100baseTX <full-duplex,flow-control> 1000baseT <full-duplex> 1000baseT <full-duplex,hw-loopback> 1000baseT <full-duplex,flow-control> none

(or) u can get from system preferences and network setting.
select the device
gud luck
