После преобразования .dmg в img через dmg2img, вы можете смонтировать img файл следующим образом:
mkdir /mnt/img_mnt
mount -t hfsplus your_file.img /mnt/img_mnt
Некоторые пакеты должны быть установлены, чтобы легко управлять img файлами.
например: hfsplus, hfsprogs пакеты на базе debian.
На Rhel : kmod-hfsplus
