When will OS X mount error solved?

Hi, as amateur i find out easy way to kick this problem.
1.download this app balenaEtcher - Flash OS images to SD cards & USB drives
2.download some of these disk images from here Download - OSMC

  1. run Balena and mount disk image straight on your SD.
  2. put SD in your Pi … done. Instalation will start.

Hope it will work for you too.
