I dont think it will be more than half a year, but its not something i am in control off. He thought he would be done this year, but it does not look like it... The new macs that just came out are not having intell chips so I don't even think you can use the pc kala on it. If you have an older mac that has not been upgraded to a newer os in the last 18 months, its pretty easy.
I have not used Kala till now, but have been curious to try it.
I am planning to buy a Chromebook, can I install Kala on it?
No you need a full windows OS for it.
