NameChanger
NameChanger is a macOS file-renaming utility that helps you rename batches of files with previews before applying changes.
What is NameChanger?
NameChanger is a macOS utility for renaming groups of files quickly and accurately. It is designed for people who need to clean up filenames, add numbering, change text, adjust letter case, or apply date-based naming to many files at once. The app shows a live preview of the new filenames as you type, which helps users confirm the results before committing changes. Common workflows include organizing photos, standardizing document names, preparing media files, and tidying downloads or project folders. NameChanger also supports drag and drop, multiple renaming methods, and options for handling file extensions and uniqueness. It is published by Mickey Roberson through MRR Software and is aimed at Mac users who want a focused batch renaming tool rather than a broader file manager.

Safety overview
Status: Safe
NameChanger is a straightforward file-renaming tool for macOS. It needs access to the files and folders you choose to rename, and that access is normal for its purpose. The main practical risk is accidental renaming if a rule is applied too broadly, so it is wise to review the preview list before confirming changes, especially in folders with important documents or media.
Recommendation: Keep NameChanger if you regularly rename groups of files or want a faster way to standardize filenames on your Mac. If you no longer use it, removing the app is usually fine and only affects its renaming features and any saved app preferences or history.
