How to Change File Names in Bulk in macOS

This emindsca teaches you how to rename multiple files in macOS at the same time.


1. Open Finder on your Mac. You’ll usually find this icon on the Dock.

2. Open the folder with the files you want to change.

3. Choose the files. Hold Command while clicking each file to select more than one at a time. You can also draw a box around the files you want to edit if you prefer.

To select all files in a folder, click anywhere in the folder and then press Command+A.

4. Click the Action button. It’s at the top of the Finder window.

5. Click Rename [number of] Items.

6. Click Format from the drop-down menu. It’s the menu at the top of the set of rename tools.

7. For the style format, choose a name format. Depending on your requirements, select Name and Index, Name and Counter, or Name and Date.

8. Fill in the “Custom Format” box with a name for the files. This will be the name that appears at the start of each file name.

For example, if you enter “Cat” and choose “Name and Counter” as your format, the files will be named Cat-1, Cat-2, and so on.

9. Enter a starting number. If you’re numbering the files, you can start with 1, 2, or any other number.

10. Click Rename. The selected files are now renamed sequentially using the formatting you entered.
