How to Batch Rename Files in Mac OS X Using Automator

Batch renaming files on Mac OS X can be a tedious task, especially when you have a large number of files to rename. Fortunately, you can automate this task using Automator, a built-in application that allows you to create workflows to automate repetitive tasks on your Mac.

Here are the steps to batch rename files in Mac OS X using Automator:

1. Launch Automator by searching for it in Spotlight or by navigating to Applications -> Automator.

2. In the Automator window that appears, select "Workflow" as the type of document to create.

3. From the left-hand sidebar, select "Files & Folders" and then drag the "Get Specified Finder Items" action to the workflow area on the right.

4. Click the "Add" button and select the files that you want to rename.

5. From the left-hand sidebar, select "Utilities" and then drag the "Rename Finder Items" action to the workflow area.

6. In the "Rename Finder Items" action, choose "Replace Text" from the "Rename" dropdown menu.

7. In the "Find" field, enter the text that you want to replace in the file names.

8. In the "Replace With" field, enter the text that you want to use to replace the text in the file names.

9. If you want to add a suffix or prefix to the file names, you can choose "Add Text" from the "Rename" dropdown menu and enter the text that you want to add in the appropriate field.

10. Click the "Run" button to test the workflow.

11. If the workflow works as expected, save it by selecting "File -> Save" and give it a descriptive name.

12. To run the workflow on a batch of files, simply drag and drop the files onto the saved workflow.

That's it! Your files should now be renamed according to the rules you specified in the Automator workflow. This can save you a lot of time if you have many files to rename.
