The Mac App Store isn’t even one month old and we have already heard several stories of success from Mac developers. The most notable one comes from Pixelmator, which grossed $1 million in less than 20 days into the new store; we have covered other experiences from developers in our Mac App Store hub. Autodesk (makers of AutoCAD) announced in a private event in San Francisco that the Mac App Store version of Sketchbook Pro, a painting and drawing application, has sold twice as many copies as the regular version did in the entire year. In 20 days. That’s quite an achievement, I would say.
The Loop reports Autodesk also had to ship a different version of Sketchbook Pro in order to be approved by Apple:
For example, Mac App Store apps aren’t supposed to use private APIs, can’t incorporate their own end user licensing agreements, and can’t employ separate copy protection. As a result, sharing code with the iOS version made the process easier, though SketchBook Pro is scaled up to take advantage of the increased processing power and memory footprint of the Mac.
