macOS passes 'open file/open folder' events to a running application. Windows starts another application instance. AFAIK, it is impossible to change.

The only way to launch additonal application instance(s) is to use command-line (Terminal window) by one of these two options::

  • open -a -n /Applications/FastRawViewer.app
  • /Applications/FastRawViewer.app/Contents/MacOS/FastRawViewer
