If you find yourself performing the same actions on your Mac again and again, open up Automator and see if you can program a workflow, which you can save as an application and run from your Dock or with any application launcher. Alternatively, you can set up a Folder Action, which means that Automator watches a specified folder, and anything you put in that folder gets processed instantly.
In our example, we’ll set up an Automator workflow to resize images for our blog, save them as JPEGs, and rename the files. But poke around Automator’s actions library and you’ll probably find ways to speed up your own most-performed tasks, too.
