you might run it with an in-memory library via terminal:
/Volumes/darktable/darktable.app/Contents/MacOS/darktable --library :memory:
or use a separate config directory:
/Volumes/darktable/darktable.app/Contents/MacOS/darktable --configdir ~/.config/darktable_test
also keep in mind that if you don’t disable writing sidecar files these can be messed up
both packages are unsigned, you might need to allow execution via terminal: " xattr -c <path/to/application.app> "
