Are there any open-source photo management suites for Mac power users, similar to Lightroom or Aperture?

I'm looking for an open-source photo management and editing application for macOS, ideally something comparable to Lightroom or Aperture. Important features include good performance, RAW workflow support, metadata and import automation, and especially scriptability for custom batch tasks such as renaming files on import and applying metadata automatically. Cross-platform options are fine as long as macOS is supported. Are there any realistic choices, or is this still a gap in open-source photography software?

Have you taken a look at Darktable? It seems to be open-source and Linux-only.
Feature description
It needs to be fast
It is quite quick and supports computations on the GPU using OpenCL.
Scriptability
It supports scripting using LUA. This is a pretty recent feature (as of '15), so the API is still small.
Keyboard-based interaction mode
You can do quite a few things using the keyboard. You have to check this yourself.
Extensibility
If you can't do it with Lua, you can hack the C code. Well...
Real-time GUI manipulations
Most filters are reasonably quick, so I think yes.
Ability to identify objects/people in photos
Nope
Photo and/or meta-data manipulation on multiple devices
It supports making temporary local copies of images on a remote drive for manipulation (and presumably back-syncing). I'm not using it this way, so I cannot comment much.
Friendly workflow
It doesn't touch the files but stores everything in sidecar files. This approach is extremely great and makes DT compatible with other programs (at least on the common meta-data properties). While it has a database to speed things up, the sidecar files allow you to copy photos around while retaining the manipulations you made with Darktable.

Generated from our catalog & community — verify before relying on it.
There doesn’t appear to be a full open-source Lightroom/Aperture equivalent for macOS that meets an advanced power-user feature list, especially if speed, deep DAM features, and strong scriptability are all required.
From the suggestions given:
- Darktable is the closest match in spirit. It’s open-source, fast, supports GPU/OpenCL acceleration, and has Lua scripting for automation. However, the scripting API was described as limited, and one answer notes it as Linux-only in that context, so macOS support may not have been reliable at the time.
- F-Spot was mentioned as an interesting project with overlapping goals, but not as a complete answer.
- RawTherapee was noted mainly for RAW conversion, with photo-management features described as a longer-term goal rather than a finished solution.
So the practical answer is: no fully comparable open-source suite was identified. If you want the nearest open-source option to investigate, start with Darktable; otherwise, expect to combine smaller tools rather than find one app that does everything Lightroom or Aperture does.
