This is only written from the perspective that you’ll be using OSX. 

Step one — Get network access.

This should be pretty simple if your trying to use wifi at a hotel or from behind some sort of pay wall. Your already connected. If your not connected and the wifi access point you want to use isn’t password protected, connect :).

Step two - Finding those mac addresses.

To do this you’ll need to open the application ‘terminal’. You can do this by pressing cmd + space, type terminal and hit enter. Once you’ve got it open, run the following command: arp -na.

This should list some network devices and print out something like below.

~ arp -na
? (192.168.0.1) at 7c:4c:a5:9d:6e:a8 on en0 ifscope [ethernet]
? (192.168.0.13) at ac:bc:32:89:e0:1b on en0 ifscope permanent [ethernet]
? (192.168.0.26) at b4:ae:2b:69:da:26 on en0 ifscope [ethernet]
? (192.168.0.255) at ff:ff:ff:ff:ff:ff on en0 ifscope [ethernet]
? (224.0.0.251) at 1:0:5e:0:0:fb on en0 ifscope permanent [ethernet]
? (239.255.255.250) at 1:0:5e:7f:ff:fa on en0 ifscope permanent [ethernet]
? (255.255.255.255) at ff:ff:ff:ff:ff:ff on en0 ifscope [ethernet]

The mac address so the string of characters after the word “at” ff:ff:ff:ff:ff:ff

Step three - Changing your mac address.

To change your mac address keep terminal open. You’ll need to pick one of the mac addresses from the list and use that in the command below by replacing the one there.

sudo ifconfig en1 ether aa:bb:cc:dd:ee:ff

You may have to repeat the proccess of changing the mac address until you find one that has already paid or been granted access to the ‘premium’ network.

But, once you’ve got it you’ve got it for as long as the other computer has it.
