How to blur faces in photos and videos on a Mac
Built in: macOS has no built-in way. In Preview you can draw a shape over a photo by hand, one at a time.
With Garlic
- Start dragging the photo or film and hold ⌘ Command.
- Drop on Redact. Garlic finds faces (and text in photos) on your Mac.
- A covered copy appears beside the original.
To remove location and camera details as well, hold ⇧ Shift and drop photos on Clean.
