Other procedure:

sudo ifconfig en0 ether 00:00:00:00:00:00 ,where en0 is the network interface you wish to change the MAC address of, and 00:00:00:00:00:00 is the target MAC address.

TCP/IP Configuration for MAC OS

TCP/IP Configuration for MAC OS

  
1)Setting up a static IP for MAC OS :

Click the Apple icon in the upper left hand corner of your screen, Then click the System Prefreneces.. option.

 

2)In the Internet & Network section click the Network icon. 

 

3) Select the network connection you use to connect to the internet. It will be the one that has a green dot in front of it. The green dot means the connection is active. Then click the Configure button which is close to the bottom of the screen. 

 

4) Select LAN card then click configure options, Then Click the Configure IPv4 drop down box and select the DHCP or Manually option

 

5) Click the Configure IPv4 drop down box and select the Manually option. If you wants to put IP address manually 

Note:

As you can see the Subnet Mask and the Router fields are already filled out. Pick an IP address and enter it into the IP Address box. The IP address you choose should be very similar to the router's IP addres. Only the last number of the IP address should be different. If the router's IP address is 192.168.1.1, I might choose 192.168.1.10. The IP address you choose should end with a number between 1 and 254, and should not be the same as the router's IP address. Every device that connects to your network needs to have it's own IP address. I'm going to recomind some Static IP Addresses for you to use here. Just enter your computer's default gateway and the ip address your computer is currently using into the form below. Then click the Find Static IP Addresses button.

We also need to enter the DNS servers that your computer should connect to. The easiest way to find out what dns servers to use is to give your ISP a call. Ask them what DNS servers you should be using, and they will most likely give you two ip addresses to type into the DNS Servers box on this page. That is all that there is to configuring a static IP address on your Mac.

That's it you should be done! If you can't connect to the internet go back and change your configuration back to what it originally was. Remember that all of the computers on your network need to be setup like this, and every one of them needs to have a different IP address!!!! 

TCP/IP Configuration for MAC OS Another Easy Procedure:
