Convert Dmg To Iso Mac
The ISO file format is pretty much entranched in the PC world as THE format to use for CD/DVD disk images. The advantages of this format are plenty – It is a standard open format and tools to work with it are readily available for all operating systems, Windows, Unix/Linux and OS X.
While Mac users can use the ISO format on their machines, Most software on OS X is distributed as a DMG file. The DMG file format has a couple of arguable advantages over the ISO format like encryption, compression etc., but the truth is that the rest of the world uses ISO and there is no way easy way to use DMG files in the PC world.
I faced this dilemma at work a couple of days back when I had a DMG file in my hand and had to burn it to a DVD but I was using a Linux machine.
I tried searching online for solution to burn a DMG on Windows but couldn’t find any free utility. So, I searched for the next logical solution. Convert the DMG to ISO and I found a way to do it – and the good thing is that the tool to be used for the conversion comes with Mac OS X and is a simple command line utility.
This method only works on a Mac, so you have to convert the DMG file to an ISO on the Mac itself and then transfer and use the resulting ISO on your PC. The utility to be used for the purpose is hdiutil and the complete command is:
Below is the screenshot of the command that I used to convert my DMG file to ISO.
The above command will create a file with a .cdr extension, which stands for a CD/DVD master. If you want, you can rename it with a .ISO extension and it should still work fine. Copy it over to your Windows or Linux/Unix machine and you’re all set.

You can now use Nero, cdrecord/wodim or the OS’s built in ISO burning tools to burn this ISO file to any media.

Not everyone is a 'fanboy', dedicated to just Microsoft, or just Apple, or just Anything. Some of us like to use more than one computer and when we do, we often throw many operating systems into the mix. That's why we end up with problems like having to read Apple's DMG format on a foreign system.
And, yes, some people are newbies, but you don't have to insult them for asking questions on the 'wrong' forum. How does that help the 'IQ of the world'? I understand that you're mad at everyone for wasting your time by forcing you to read posts that you find idiotic. Congratulations, your petty-poopy tirade just extended the thread of idiocy.
There are so many better ways you could have handled this. May I demonstrate?

For example, you could gently point the newbies to where they can find more expert (and perhaps friendlier) advice. 'Sorry, I don't know much about GNU/Linux, but I hear the folks at forums.debian.net are real nice.'
Or, if you have the knowledge, you could share it with them, for example, 'Well, in GNU/Linux, Apple's DMG files should automatically be readable from your desktop when you double-click on them. If not, run this command: sudo mount -t hfsplus -o loop thisisthefile.dmg /mnt, and it'll show up.'
If you can't do either of those, the next best thing is to say nothing. That right, even though you see somebody who's such a noob that they don't even know who to ask for help, the correct action is to just let them be. Someday, you'll try something new (or at least I hope you will) and you'll appreciate it when people don't pounce on you for your mistakes.
