but remember:
1, before you do the first reboot, make sure that the Ethernet Built In in the org.chameleon.boot is checked. you can do this using Chameleon Wizard.
2, then, do every thing in the above url and disable the WIFI on your E6410 to make sure that the ethernet on the laptop be recognized as en0 when booting up.
3, reboot and manually add network interface in System Preferences. Ethernet goes first. and use ifconfig to make sure that the ethernet card is en0.
4, turn on your WIFI switch. now you may not have any working Internet. just reboot again.
5, try logging into your AppStore.
this does not assure you have a working iMessage. I am still working on that.
