NRG disk images
NRG is native disk image file format used by popular Windows burning software called Nero Burning ROM. It is also available in version for Linux, however there is still no Nero version for Mac OS X.
The easiest way how to open, or burn .nrg files on Mac is to convert them in to standard ISO 9660 disk image format that is natively supported by Mac OS X operating system.
Some sources inform that you can just rename .nrg file extension to .iso file extension and Mac applications will be able to open them. However this process doesn't work!!
