If FL needs crossover for mac, I would not use it. Until it's an actual native port it will be strange.
edison is alright, it has its limitations but i can see that grow in the future. I've been saying it since 2.54, fl is probably the most adaptive platform around and image-line does a great job on consistent (and functional) upgrades. heck, they even still support dx plugs lol
What more would you like edison to do?
