SO I bought the lgp lite the other day and you have to plug it into a computer to do the driver update well I download the file I then have to unzip the fil I do that but it says that it’s a dmg file so I downloaded a dmg file opener and says it’s not in the dmg file file format so I’m stuck as in what I can do to get it working
