Today I will introduce you to Automator with a short and interesting example. Automator is developed by Apple and was first released with Mac OS X 10.4 Tiger. It is a powerful environment for automating repetitive tasks. A wide range of applications are supported, including for example Finder, Safari and Xcode. It can also work with third-party applications like Adobe Photoshop and Pixelmator. Automator provides an interface for automating tasks without the knowledge of programming and scripting languages. Tasks can be recorded as you perform them. In addition, there is a library where predefined tasks can be selected from a list. In this tutorial we will create an useful application for batch scaling images without a single line of code.
