Mount .NRG image file on OSX 10.6

Solution 1:

A little googling led me to this thread on MacRumors.com

It appears that if the ISO is a single session CD image you can just knock the first 600 bytes off with a terminal command and it'll be readable as an ISO (change file type to .iso after performing the command).

I'd recommend making a backup of the .nrg file before trying this though!

$ dd if=image.nrg of=cdrom.iso bs=512 skip=600

Also, If you're just looking to extract pictures from the disk, File Juicer may also be worth a look!

Solution 2:

Had the same experience as the OP. Tried using nrg2iso, tried renaming the file to .iso and also tried the dd command from that MacRumors thread. Nothing worked.

However, I then found nrg4iso which worked perfectly! The project has been abandoned since 2007 but it still works.

Solution 3:

dd variant not work for me. So, i find another one with poweriso:

Use: ./poweriso convert ~/Desktop/image.nrg -o ~/Desktop/image.iso -ot iso
