From the developer:
ElectricDesignPro is a graphical environment for creating electrical circuit plans, wiring diagrams via an intuitive user interface and electrically intelligent symbols in 2D. There are many predefined nice electrical, circuit objects for you to add to your design. You can right click on a group of objects, then select "Add to template list" to save them so that you can reuse it later.
You may want to check out more software for Mac, such as Corel Painter Sketch Pad, ImageBuddy or Downsize, which might be similar to ElectricDesignPro.
