I reformatted the SD card using the Formatting Tool from SD Memory Card Formatter for Mac Download | SD Association
because the system got corrupted ( issues I had with the wifi) and I was not able to boot it again
When I launched the raspberry using the data the formatting tool provided, I clicked on the only option the tool had: raspberry.
Please, help me on how I install OSMC on this card; I used it before ( a friend gave it to me with OSNC installed already).
Thanks
