After Mac 10.5 release I couldn't use DMGextractor to extract .dmg file to iso file.
Actually I can extractor .dmg file and got iso file, but when i use
mount -t hfsplus -o loop /directory/location_of_iso.iso /mnt/mountpoint
got error message like
wrong fs type......
But I found HFSexplore could read .dmg file directly under windows.You can download from hem.bredband.net/catacombae/index2.html
much easier than use dmgextractor to convert to iso then read file.
