I'm comparing MacDaddyX to ChangeMAC.
I prefer ChangeMAC, it's simpler and gives it the K.I.S.S.

Compared to ChangeMAC, MacDaddyX looks cooller, works not as much (about 65% of the time), has a more extensive list of OIDs (although I have no use for this), and a nice log thingy (which i also don't use).

MacDaddyX is a throbbing pain in my donkey, at least for now.
You can't use the edit menu at all (lame!).
I want to change the MAC on my airport card (en1), but it ALWAYS switches back to ethernet (en0) after i do anything!!! plus it fails to change the MAC too much, which in combination with the last complaint means that when I go to press the change button after a failed attempt, it's now changing my ethernet's MAC address. this means i have to take a bunch of steps to find the hardware id of the en0 and switch it back, and then try again with the en1 MAC. guess how many times I'm trying to pass out and need to get this done but I end up in this hellish loop!!!! AAAAHHHH.

I need software to do one thing here, and of course the more easily and consistently the better.
I don't think folks who'd change their MAC addresses would really care about the looks.

Maybe when it works I'll like it.
