The interface is very dense when you first open it, with options across almost every square inch of the screen, so the tutorial will help you find what you need. After loading it from your Applications folder, you can start using it right away, though it recommends you open the Help folder, a recommendation we agree with. Installation of MacStitch is straightforward and takes only a moment. The result, while strict in its learning curve, can be an extremely powerful tool for anyone who creates their own patterns or wants to customize the patterns they purchase online on their Mac.
