Automator is an application developed by Apple Inc. for macOS that allows users to automate repetitive tasks through point-and-click or drag-and-drop). It enables the repetition of tasks across a wide variety of programs, including Finder, Safari, Calendar, Contacts, and others. Automator can also work with third-party applications such as Microsoft Office, Adobe Photoshop, or Pixelmator).

Automator documents are called workflows, and are made up of actions. Workflows are run sequentially, with each action being given the previous actions output, which it can then process or act upon. Variables can be specified, which can be modified or processed by subsequent actions. Workflows can also incorporate loops and variables).

Automator provides a graphical user interface for automating tasks without knowledge of programming or scripting languages. Tasks can be recorded as they are performed by the user or can be selected from a list. The output of the previous action can become the input to the next action.

Some of the features of Automator include:

• Built-in actions: Automator comes with a library of actions such as file renaming, finding linked images, creating a new mail message, etc.).

• Custom actions: If the task you need to automate isn’t in the list of built-in actions, you can add your own scripts, such as AppleScript and JavaScript scripts, and shell commands to your workflow.

• Variables: Automator allows you to specify variables from one step to be stored so they can be passed to a step further down.

• AppleScripts: Automator can also run AppleScripts, making it even more powerful.

Automator is a powerful tool that can help users save time and increase productivity by automating repetitive tasks.
