I have read so many articles and forums about how to convert a dmg file to iso file on Mac so that it can be burn on Windows platform. Eventually, i have found the solution on a few forums but sadly, nobody dare to sum it up or report back the result. So i went away and tried all the methods i’ve read and here are two methods that make most sense to me.

Method 1: using Terminal

To change a file with dmg extension to iso, just open up the terminal window and type the following command:

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

Above command will simply replace /path/to/yourfilename.dmg with the path and name of the existing .dmg file, and then replace /path/to/newfile.iso with the chosen path and chosen name for the converted iso image.

Method 2: using disk utility, this will work with leopard DVD also

1. create a new image using format DVD/CD Master from your existing .dmg image

2. simply change the .cdr.dmg extension of the file to .iso (command key + i)

That’s it. However there are methods for converting dmg file to iso on Windows as well which one of my popular post: burning dmg on Windows PC can be applied to. But that isn’t throughly enough so i will explain more on that in my coming post.
