Hi, @Bikram40! I faced the same issue and found a solution. If you want to open .dmg file you should follow the next flow:

1. Mount your .dmg file using command hdiutil mount <name>.dmg (or $filePath from example) ;
2. Install the application by copying files to /Application folder with command cp -R /Volumes/<title from config.json>/<app name>.app /Applications;
3. Unmount .dmg file hdiutil unmount /Volumes/<title from config.json>/;
4. Additionally I added deletion downloaded .dmg file command rm $filePath.

Also you can join all commands in one: hdiutil mount $filePath && cp -R /Volumes/<title from config.json>/<app name>.app /Applications && hdiutil unmount /Volumes/<title from config.json>/ && rm $filePath

The full implementation of the method in my project looks like this:

 Future<void> openDMGFile(String filePath) async {
    await Process.run('sh', [
      '-c',
      "hdiutil mount $filePath && cp -R /Volumes/InAppUpdateDesktop/in_app_update_desktop.app /Applications && hdiutil unmount /Volumes/InAppUpdateDesktop/ && rm $filePath",
    ]);
  }
