Seeking Raw Therapee Help w. Apple Photo Program

Hello. I’m learning to work with RAW files. I’ve transferred some RAW files (taken on Ricoh GR II) to Apple Photo on iMac. I can see the pictures in Photos where they are labeled DNG. However, after installing RT the RAW files are not appearing in RT. I toggled through various folders of mine displaying in the left margin of RT but the files are not loading. Grateful for guidance.

The RawTherapee file browser doesn’t show files recursively. Are you sure you’re in the right folder? Apple Photos stores photos in its own weird hierarchy.

You’re using RT 5.3, you have DNG ticked in Preferences > File Browser > Parsed extensions, and you double-clicked the right folder?
