Batch rename files on Mac
To batch rename files on a Mac, double-tap the right Option key and type “rename it to Invoice March”. Renames in place; the extension never changes unless asked. More than one file shows old → new names first. Undo puts them back.
How to do it
- Select the files in Finder, pick them with @ in the bar, or name them in plain words ("my last pdf").
- Double-tap the right Option key to open the bar.
- Type “rename it to Invoice March”.
- Press Return. The new file appears next to the original.
Type
- rename it to Invoice March
- add today's date to these
- number them
- replace "draft" with "final" in these
- rename my last pdf to 'need edit' at the end
What you get
Renames in place; the extension never changes unless asked. More than one file shows old → new names first. Undo puts them back.
The original is never changed or overwritten. Undo trashes what the job made.
Dates are written like 2026-11-02. Numbers count from the oldest file, or say “newest first”.

Limits
