Doing the procedure again fixes it, no issues. FYI, system updates seem to undo this little change reverting back to the original MAC address. Doing the procedure again fixes it, no issues.

I am able to successfully change the MAC address and it does in fact show up on the router, in the DHCP table, and via a network scan done by another device.

However, the GUI still shows the Apple MAC address, though it doesn’t seem to make a difference out on the network.

I need to spoof my MAC address to get back into my iTunes match account on the same damn laptop/account I bought it on.. I have 1 month left before it resets, but now that I know I can just change my MAC address I'd definitely do that instead... Any help would be deeply appreciated!
