Hi Sir, I have two questions for you.
I will purchase the Full Version for Mac asap.
If I want to install it on my iMac 21 at home and on my MacBookPro too, need I to purchase 2 licenses? or 1 license works on both my computer?
And the 2nd question is: what differences from "latest build" and "old build" ?
Thanks in advance

Hi, you only need to buy one license, you can install it on both of your computers. Generally you should just download the latest build. (The old build is basically kept on the site just in case there is some problem with the latest build.)
