Converting MAC .DMG to .ISO files

[mj213]

Hey all you fellow Mac users. I have to convert my 4 .DMG image files (OS X 10.4) to .ISO so I can burn them on my PC. My Mac doesn't have a burner, and apparently I need a Mac compatible drive, so I'm trying to burn them onto my XP machine.

I have tried dmg2iso and it doesn't work. I've tried MagicISO, and it takes forever. Apparently, it converts at a rate of 100kb/minute? I let it run for 2 hours and it got 2% completed of ONE 600MB file. That means a total of 400 hours for 4 cds. FUCK THAT.

Before someone has something to say like "Go buy the OS blah blah". If I had the money, I'd put it into my car. I am only doing this to learn more about the Mac. I need helpful information.

I don't know anybody else with a Mac either.

You can use the terminal to do it.

hdiutil convert /path/to/filename.dmg -format UDTO -o /path/to/savefile.iso

replace path to filename.dmg with the path to the file (easiest way is to do it on the desktop), and also replace savefile.iso with whatever name you want .iso.

So, example on mine using somedmg.dmg on the desktop:
Open terminal

$cd Desktop
$hdiutil convert somedmg.dmg -format UDTO -o somedmg.iso

And that is it. hdiutil will output a file with .iso.cdr as the extensions, but you should be able to remove the .cdr (just delete it) and have it work out ok.

Hope this helped!

Thanks for the info - I will try to do that if I can manage to network my two computers. I found a setting to use Windows file sharing in the Mac, but I know it needs to emulate the workgroup name for the other computers to recognize it.

If you can't get that figured out, you can always put it in the "Sites" folder in your home directory and turn on personal web sharing. Then all you have to do is open up IE/Firefox on the other computer and type in <ip address of the mac>/~username/name_of_image.dmg

If you have Leopard (10.5) then setting the workgroup is pretty easy, its in the System Preferences. In 10.4 you have to use /Applications/Utilities/Directory Access, which is a little more involved but not bad.

I'll try the sites folder - problem is I'm needing to put files from the PC onto the Mac - it's OS X 10.2 Jaguar. I'll let you know how that goes!
