The serial, how did you get it working? I tried generating a few of them and they never worked. I got one from my MacBook to put on another computer, it worked for a while but one day clover (osx bootloader for non Mac hardware) updated and it stopped working. I am not sure if the serial had an issue or something, did you have a similar issue? I ran it on bare metal and my use was different (just to have my messages and iPhone synced) so it worked ok for me until i updated it and stopped using osx.
