I got this from another forum,
it works...
I usually burn diskcopy img files (toast images, iso image, what have you) using cdrecord on a linux system using cdrecord, but I recently had an occasion to burn a dmg. I tried it with cdrecord, which resulted in a coaster.. but it turns out that Apple has provided us with a command line utility to convert between disk image formats. Behold:
[think:~] oliver% hdiutil convert test.dmg -format UDTO -o test.img
and voila, test.img is ready to be burned with cdrecord on unix. hdiutil actually converts between lots of formats:
DC42 - Disk Copy 4.2
RdWr - NDIF read/write
Rdxx - NDIF read/only
ROCo - NDIF compressed
Rken - NDIF compressed (KenCode)
UDRW - read/write
UDRO - read/only
UDCO - compressed
UDZO - compressed (zlib)
UFBI - entire device
UDTO - DVD/CD master
UDxx - UDIF stub
how about that? the power of unix and a command line..
hope this helps someone
cheers,

Have fun
