i had to make an iso file from a real cd under [mac osx] and thought
this tip might help someone:

1. put cd in drive, open `Application/Disk` utility
2. select the cd from the list on the left
3. click on file -> disk image from `disk2c0` (nameofyourcd)
   this creates a `.dmg` image, now we have to convert it to an `.iso` image:
5. open a `Application/Terminal` and type "`hdiutil convert disk2s0.dmg -format UDTO -o file`" where `disk2s0.dmg` is the file that was created by disk utility.
5. rename `.cdr` file to `.iso`
6. mount to test image

all done, hopefully that helped you.
