darktable Top pick
Open-source RAW workflow with a catalog and optional AI tools
Metadata checked Aug 18, 2026
Rank 1 for the strongest combination of Luminar-like photography workflow, current maintenance, optional AI capabilities, and first-party macOS DMGs.
The closest overall match for a photography workflow: it combines a searchable image library, non-destructive RAW processing, local adjustments, and optional AI masks, denoise, and upscaling.
- 01 Non-destructive RAW development and export
- 02 Database-backed lighttable for organizing photo collections
- 03 Masks, retouching, color, tone, and exposure modules
- 04 Optional AI masks, denoise, and upscaling
- The module-based interface is considerably more technical than Luminar Neo.
- AI features are optional and off by default, and require model downloads; they do not reproduce Luminar's full sky-replacement or generative toolset.
- Current project documentation lists macOS 14 or later for Apple Silicon and macOS 15 or later for Intel.

RawTherapee
High-control RAW development without a subscription
Metadata checked Aug 18, 2026
Rank 2 for excellent RAW output, active 2026 development, a long-running GPL community, and an official macOS build; it is less automated and less catalog-oriented than Luminar Neo.
Full review — capabilities, 3 caveats, evidence
A technically deep RAW processor for photographers who prioritize demosaicing, exposure, color, sharpening, and noise control over cataloging or one-click AI effects.
- 01 Detailed RAW demosaicing, exposure, color, and tone controls
- 02 Batch processing with sidecar-based edits
- 03 Noise reduction, sharpening, HDR DNG, and non-RAW support
- 04 Current universal macOS package for Apple Silicon and Intel
- It does not provide an integrated asset-management catalog comparable to Luminar's library.
- Its many expert controls make quick, preset-driven enhancement less immediate.
- The 5.13 macOS page requires macOS 26 on Apple Silicon or macOS 12 or later on Intel.

GIMP
Full-featured free image editing for macOS
Metadata checked Aug 18, 2026
Rank 3 for exceptional community trust, broad manual editing capability, active maintenance, and strong macOS packaging, with a weaker match for Luminar's RAW catalog and AI-first workflow.
Full review — capabilities, 3 caveats, evidence
A mature general-purpose editor for retouching, layers, masks, compositing, and creative finishing. It covers Luminar's pixel-editing side well, but is not a catalog-first RAW or bundled-AI workflow.
- 01 Layered raster editing, retouching, masking, and compositing
- 02 Color management and broad format support
- 03 Scriptable and extensible through plugins
- 04 Separate Intel and Apple Silicon macOS DMGs
- RAW development commonly requires a separate converter or plugin workflow.
- It has no bundled Luminar-style AI editing suite, photo catalog, or preset-driven workflow.
- The GitHub repository is an official read-only GNOME mirror; canonical development is linked from the project documentation.
