how to burn a .nrg file on a mac
 

just downloaded a 3.9 gig .nrg file that i need to burn on a mac. tried the "create disk image" thing in toast and it didn't recognize the .nrg file. duplicated the file and replaced .nrg with .iso.....and toast saw it but wouldn't go through with the disk image creation. i know that with a pc i need to run a probram called "nero" or something. is there a mac equivilent?

TIA
