First of all i've got to say a big thank you to all the Niresh team, The OS Mavericks is working smoothly and doing the exact job as i wanted to. But i have one small problem. "Facetime/Messages" I cant seem to get my messages to work, When logging in it says "Unable to Log in" Somthing along those lines. Can this be fixed without having to go through the whole installtion process again? Thanks.
