RawCull

RawCull is a native macOS app for reviewing RAW photos before editing. It shows fast previews and camera information, records picks and ratings, groups similar frames, and copies the selected files to an editing folder.

This guide describes the RawCull 3.2 workflow. It requires macOS 27 (Golden Gate) and an Apple Silicon Mac. Optional AI features run locally for semantic search, visual similarity, and deeper analysis of selected photographs. See Release Notes for version-specific changes; a development changelog does not confirm App Store availability.

Install

Download RawCull from the Apple App Store.

Quick Start

  1. Select Add Catalog and choose a folder of RAW files.
  2. Review the photos in Loupe or Grid view.
  3. Press P to keep, X to reject, or 2–5 to rate a photo.
  4. Use Sharpness, Similarity, or AI Analysis when you need help comparing candidates.
  5. Select Copy, choose all rated photos or a minimum rating from 2 to 5, and choose your editing folder. Check the Dry run result before copying.

Ratings, sharpness results, and catalog state are saved automatically on your Mac.

Requirements and Supported Files

  • macOS 27 (Golden Gate)
  • Apple Silicon Mac
  • Sony ARW catalogs
  • Nikon NEF catalogs (experimental)

Sony ARW is the primary format. Some functions depend on camera metadata and the RAW support available in macOS. Demosaiced RAW previews and exports are Sony-specific; RawCull uses embedded previews when RAW development is unavailable.

If Something Is Missing

  • No focus marker: check Focus Points. Not every file contains a supported autofocus location.
  • No developed RAW preview: use the embedded JPG preview. Development support depends on the camera file and the installed macOS decoder.
  • Similarity or search unavailable: check the CLIP model in AI settings, then index the catalog as described in Similarity, Bursts, and Search.
  • Slow browsing or memory warnings: check Cache and Memory Pressure.

For a bug report, include the app version, macOS version, camera model, file format, and steps that reproduce the problem. Contact details are on the About page.
