Install cullnest in Lightroom Classic

Check compatibility

For Apple Silicon Macs running macOS 14 or later + Lightroom Classic.
Model and runtime included.

Use an Apple Silicon Mac with macOS 14 or later and Lightroom Classic. Keep the complete plugin folder with its bundled runtime and model.

Before you begin

1. Add the Lightroom plugin

   In File → Plug-in Manager, remove the old plugin registration and add the complete LRSmartCulling.lrplugin folder. Enable only one instance and restart Lightroom after upgrading.

2. Start with a small set

   Select photos and open cullnest: Culling Settings. Choose a condition, retention count (1–9), rating action, and existing-rating policy. Start Culling runs analysis and applies those settings directly. Review results through Results / Groups / Cleanup.

Nine languages, inside the plugin too

English, Simplified and Traditional Chinese, Japanese, German, French, Spanish, Brazilian Portuguese, and Thai. Follow Lightroom automatically or choose a language manually. Applying a language keeps your settings and does not start analysis.

Installation and analysis troubleshooting

If menus still show an old version, enable only one plugin instance and restart Lightroom. If analysis cannot start, keep the entire plugin folder intact and check that the original photos are available. Contact support with the version and error message; do not send original photos unless needed and agreed.

What has been validated so far?

V1.3 has recorded native runtime, grouping, cache, cleanup, and multilingual regression tests. Settings windows have been checked in Lightroom. Full grouping edits were mainly tested with SDK simulations and an eight-photo pipeline; real catalog ratings were not changed in these tests. Start with a small set.
