how to make an iso

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:
4. 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.
