I also bought the mac version but the display on my mac is to small to fit the view I like so I have installed on my touch screen HP Pc that I had to upgrade to windows 10 (was free). Now I have a huge touch screen but yes sucks I had to buy another copy. Also liked djpro so much looking at upgrading my Dj controller to an actual one built for DJ Pro and guess what they come with the software so had to buy it again. How many times do you need to buy the same software?
