Convert .DMG to .ISO in Mac OS X
Let’s say you’ve created a .DMG file in OS X and you want to make it a disk image before you burn it to CD or DVD. There’s no need to buy MagicISO or other programs. Simply open “Terminal” in your copy of OS X and type in the following:
hdiutil convert /path/to/filename.dmg -format UDTO -o /path/to/savefile.iso
If you have a file like
This is My File.dmg
simply place quotes around the file you want to change. So in this cade you can type in:
hdiutil convert "/path/to/This is My File.dmg" -format UDTO -o /path/to/savefile.iso
I find it easier to place the file you want to convert to your home folder. But that’s up to you.
