A little help to keep moving
SpeedCull support
A question, an unexpected result, or something that could be smoother? Use the SpeedCull contact form on FrontierTwo.
Include your app version, device and operating system, what you tried, and what happened. For RAW issues, the camera model and exact error message help. Review diagnostics before sending; do not send passwords or your entire photo library.
Install SpeedCull for Mac
- Open the downloaded disk image.
- Drag SpeedCull onto Applications.
- Open SpeedCull from Applications and choose Open a shoot….
SpeedCull requires macOS 14 or later and supports Apple Silicon and Intel Macs. The app is Developer ID signed and Apple-notarized. macOS may show its normal first-open confirmation.
If you used the earlier Store or TestFlight edition, quit it before opening this version. Your existing photo folders and SpeedCull catalogues can still be opened; you do not need to recreate your ratings. Keep one active installation for everyday use.
Updates
Choose SpeedCull → Check for Updates…, or visit Settings → Updates. You can opt into automatic checks. Installation requires your approval and waits for active processing or exports to finish. The app checks the signed feed at speedcull.com; it does not upload your photos or ratings.
Get your star ratings into Lightroom Classic
Ratings-only plug-in for RAW and JPEG
- In SpeedCull's Sync tab, choose Lightroom Classic and the plug-in route.
- Follow the installation and one-time handoff-folder instructions. Choose the same shared folder in both apps if asked.
- Choose Send Ratings to Lightroom in SpeedCull. In Lightroom Classic, select the intended photos or folder, then choose File → Plug-in Extras → Get SpeedCull Ratings….
- Review matched images and proposed rating changes before applying.
You do not need to sync XMP first. This route transfers stars without reading all XMP metadata back into Lightroom. It is an explicit handoff, not automatic background sync.
Manual XMP route for RAW photos
- Choose the XMP route in SpeedCull and review the summary before writing sidecars.
- For RAW photos already imported into Lightroom Classic, select the relevant images in the Library module.
- Choose Metadata → Read Metadata from Files and confirm only after checking that you want the file metadata read into the catalogue.
JPEGs are excluded from XMP sidecar sync. Use the ratings-only plug-in to transfer JPEG stars to Lightroom Classic. SpeedCull preserves your original JPEG files rather than rewriting their embedded metadata.
Important: Lightroom's command reads more than stars. It can replace catalogue metadata or adjustments with file values. Back up the catalogue and resolve competing edits first. The ratings-only plug-in is the more targeted route when you only want stars.
Other photo apps
For RAW photos, use XMP if the receiving app supports sidecar ratings and follow its metadata-refresh instructions. Pick/reject flag behaviour differs; do not assume all flags transfer. Direct JPEG metadata export to other apps is not currently supported.
Availability
SpeedCull 1.0 for Mac is available free from speedcull.com. No account or subscription is required. Lightroom Classic is a separate Adobe product, not included with SpeedCull.
