# darktable

Published January 1, 2026 · Updated August 10, 2026

Open source photography workflow application

Category: Media & Entertainment · Free · Open source · Replaces Adobe Lightroom ($10/mo) · [Official website](https://darktable.org)

## Install with Homebrew

`brew install --cask darktable`

## Quick take

darktable 5.6 keeps FOSS RAW photography first-class on Mac without a subscription. The learning curve is real, Gatekeeper friction is annoying, and Lightroom still wins commercial ecosystems and some studio conveniences. For ownership-minded photographers on Apple Silicon who will learn masks and scene-referred modules, darktable remains a strong August 2026 choice.

Best for: RAW photographers avoiding subscriptions, Travel editors on MacBooks, FOSS-first studios

## What is darktable?

darktable is a free and open-source photography workflow app: a lighttable and darkroom that gives you non-destructive RAW processing without a subscription. It competes with Lightroom Classic, Capture One, and DxO PhotoLab on capability while staying GPLv3. You manage digital negatives in a database, cull on a zoomable lighttable, and develop selects through a modular pipeline that leaves originals intact.

As of August 2026 the release line is darktable 5.6.0. Official installers on darktable.org include darktable-5.6.0-arm64.dmg for Apple Silicon on macOS 14 and later and an x86_64 build for Intel, with the install page noting macOS 15 for Intel. Homebrew cask `brew install --cask darktable` is a common route. The 5.x series kept moving; 5.6 materials highlight AI tooling with GPU paths that vary by platform. On macOS the acceleration is usually turnkey once you pick the right architecture DMG.

On a Mac, Gatekeeper still quarantines the app on first launch, and darktable.org documents the xattr removal step. Performance hinges on how your Apple Silicon GPU and CPU share the load and how heavy your module stack is. Expect a steeper learning curve than Lightroom: masks, scene-referred modules, and history matter more than casual slider pushing. For ownership-minded photographers who want local catalogs and zero subscription cost, that trade is often worth a weekend of learning.

Support lives on pixls.us, GitHub issues, and the manual. Match arm64 vs x86_64 to your CPU, back up XMP sidecars with the RAWs, and pin a version during client weeks so module defaults do not shift mid-job. If you dual-run with Lightroom during migration, keep exportable catalogs and archival TIFFs outside any single app. Official 5.0.0 release notes from the 5.x era still help as baseline context for how macOS support and modern modules evolved into the 5.6 line you install today.

## Features

- **Non-destructive RAW pipeline.** A module graph that leaves originals intact and keeps history so you can revisit a look years later. Edits live in history and sidecars depending on configuration; back up both photos and metadata, not just the JPEG exports.
- **Lighttable organization.** Rate, tag, color-label, and filter large shoots before diving into deep edits. Culling on the lighttable first saves time; retouching every frame is the expensive path.
- **Scene-referred workflow modules.** Modern modules for exposure, color calibration, filmic/sigmoid tone mapping, and detailed masking. Prefer these defaults over legacy display-referred habits when you start fresh; they behave more predictably on high-dynamic-range RAW files.
- **Tethering and tethering-adjacent pro tools.** Studio-oriented features for photographers who want OSS in production environments. Test tether or network volume paths before shoot day, not on set, and keep free disk space honest on the working SSD.
- **Extensive camera support.** Broad RAW coverage maintained by the community as new bodies land. Check release notes when you buy a new camera; support often arrives through point releases rather than marketing campaigns.
- **Export presets.** Batch export to JPEG/TIFF and other targets with sharpening and size recipes for web or print. Version your presets so sharpening experiments can roll back, and verify color space before delivery.
- **AI-assisted features (5.6 era).** Version 5.6 expands assisted tools with GPU packaging. Check module docs for what is stable on Mac; some AI and GPU pieces vary by platform packaging even when the version number matches.
- **Cross-platform catalogs.** Works across Mac, Windows, and Linux for multi-OS photography shops. Agree on sidecar handling so one person's editor does not strip another's history when catalogs move between machines.

## Install darktable on Mac

Prefer official DMGs from darktable.org/install or Homebrew. Expect Gatekeeper prompts on first open. Match arm64 for Apple Silicon and x86_64 for Intel; wrong architecture installs are a recurring Mac forum footgun.

1. **Download matching CPU build.** Apple Silicon: arm64 DMG (macOS 14+ for the 5.6.0 arm64 package notes). Intel: x86_64 DMG (install page notes macOS 15 for Intel). Or `brew install --cask darktable`.
2. **Clear quarantine if needed.** If macOS blocks launch or says the app is damaged, follow official `xattr -dr com.apple.quarantine /Applications/darktable.app` guidance on the install page.
3. **Import a test roll.** Copy RAWs into a dedicated folder; avoid editing off flaky network volumes for catalogs. Import a small roll, cull, develop a few selects, and export before you trust the setup for a paid job.

## Pros

- Zero-cost professional-grade RAW workflow under GPL v3
- Active 5.6.x releases in 2026 (5.6.0 packages on the official install page)
- Deep modular editing with modern scene-referred tools and masks
- Official Apple Silicon arm64 builds available
- Cross-platform for mixed OS teams (Mac, Windows, Linux)
- No forced cloud lock-in; local catalogs and sidecars

## Cons

- Steeper learning curve than Lightroom
- UI polish lags commercial competitors
- Official Mac builds may require newer macOS than older community ports
- Gatekeeper quarantine friction on each update
- Some AI/GPU features vary by platform packaging

## Closer look at darktable on Mac

Start new edits with the modern scene-referred workflow rather than older display-referred habits. Learn masks early; global sliders alone waste darktable's depth. Keep export presets for web and print with distinct sharpening and size recipes. Decide whether edits live beside files as sidecars or in a central library path and stick to it.

For GPU work, check the release notes for your Mac build before a batch. If you collaborate, agree on sidecar handling so one person's editor does not strip another's history. Budget a weekend for module literacy; the app rewards structured learning more than casual slider pushing. Keep a Lightroom exit path during migration if clients still expect Adobe deliverables. On Apple Silicon, confirm the arm64 package and re-check acceleration notes after each point release before you batch hundreds of files. For print work, keep a separate export recipe with sizing and sharpening that you have actually tested on a lab print, not only on a laptop screen.

## FAQ

### Is darktable free?

Yes. GPL v3 free software with optional donations only. There are no paid unlock tiers for core features.

### What version should Mac users install in August 2026?

darktable 5.6.0 from darktable.org/install (arm64 for Apple Silicon). Confirm OS minimums on that page: arm64 notes macOS 14+, and the install page notes macOS 15 for Intel packages. Homebrew cask is an alternate channel.

### Does it support Apple Silicon?

Yes. Official arm64 packages are provided. Do not install the x86_64 DMG on Apple Silicon unless you have a specific reason; architecture mismatches are a common first-install failure.

### Can it replace Lightroom?

For many RAW workflows yes. You may miss Adobe's ecosystem, Sensei features, or certain tethered studio conveniences. Plan migration with exportable catalogs and archival TIFF or JPEG sets outside any single app.

### Why does macOS say the app is damaged?

Usually quarantine attributes, not a broken binary. Use the official xattr steps on the install page, then launch again. You typically need this once per update.

### Where do edits live?

Non-destructive history, XMP-style sidecars, and database metadata depending on configuration. Back up both photos and sidecars; deleting sidecars drops history even when RAWs remain.

### Is there AI in darktable 5.6?

5.6 expands assisted and AI-oriented tooling with GPU acceleration packaging. Check module docs for Mac-supported pieces; availability can differ by platform packaging.
