Primero, toca determinar si la imágen esta comprimida o no usando el comando file: $ file nombre_imagen.dmg. Si devuelve algo como VAX COFF executable not stripped – version 376, la imágen está comprimida. Si devuelve algo como Macintosh HFS Extended version 4 data, la imágen no está comprimida.

Para montar una imágen no compprimida:

1
2
modprobe hfsplus
mount -t hfsplus -o loop nombre_imagen.dmg /media/nombre_imagen

1
2
3
dmg2img -i nombre_imagen.dmg -o nombre_imagen-uncompressed.img
modprobe hfsplus
mount -t hfsplus -o loop nombre_imagen-uncompressed.img /media/nombre_imagen/nom

This is a small step towards the possible development of an open and portable audio processing platform.
