Automate the tasks you do on your Mac—even if you don’t know any programming—by using built-in actions to create workflows.
Let your Mac do repetitive tasks for you
Do you need to make the same changes to multiple files, such as changing the filenames or copying and resizing images? What about archiving or backing up your important files? If so, you can create a custom workflow, add the actions you want, and have your Mac do the work for you. To create a new workflow, choose File > New, click Workflow, then click Choose.
