Thanks for the advice.
Finally, I bought the macbook pro with retina display and I can tell that Harmony runs smoothly and without a problem so far.
Apart from that, I still think all Toon Boom products need a complete restyling of the entire interface. There’s so much wasted space, so big icons that leave you with small drawing, camera, network panels, which is what we really want to see.
It feels like you are running software from the `80s…you may thinkd this is not important but, if you spend more than 10 hours every day looking at this interface, believe me, you get tired of it.
By the way, maya 2015 works perfect in this laptop.
