    Is Disk Utility like an unzipping program or something of the sort?

    If you double click the dmg file I believe it will be unzipped into a virtual drive.

    Disk Utility is good if you want to burn a dmg file.

    Similar and apps exist that allow you to convert from dmg to iso for burning.

    Since most contain an app to drag into the Applications folder, I see them differntly though. Also so much easier than unzipping and deleting unzipped folders after.

    Just to add to that; Disk Utility works but OSX uses DiskImageMounter by default. :)

    First I was like "uh, just double click it? He must be...

    [​IMG]

    ..." but I realized, he might be a Windows user, and wondering what Windows program can open a .dmg image. In that case, I have no idea if there exists such a program.

    As nobody has clearly stated this before, I will. A .dmg file is a Mac OS X disk image file. This acts as a virtual drive once mounted. To mount a disk image just double click it in OS X. Once it's mounted you use it as a regular drive: drag and drop files in and out of it. To unmount it, just drag to the trash.

    Many downloaded applications come in disk image files.

    If you're using Windows, you're out of luck. Get a friend with a Mac to burn it to a CD/DVD.

    Burning to CD would have exactly the same effect as mounting. OS X uses images extensively, it's not a hack like it is on Windows.

    This'll all make sense once your Mini arrives :)

    Welcome to the world of computer geeks where 99.9% of members are guys (well, almost). Don't be surprised then that people assume you're a guy. :p

    Congrats on the purchase. As Nermal said, this dmg stuff will all make sense in a few hours.

    Os9

    Hey guys. Im new to macs(just got an iMac to learn on) and have a USB CD-RW hooked up and im running OS9.1 Is there any program that will let you burn to a USB Burner? I know that the OS is picking it up, because if i put a cd in it, it pops up on the desktop. Also, is it possible to burn .dmg files with OS9.1?

    I have only foggy memories of 9.1, but you might be able to find an older version of Toast that will let you do this. Also, you can upgrade to 9.2.2 for free (which may or may not be of help in doing what you want to do).

    Anyway, the updaters can be found here

    No. MacOS 9.2 and earlier versions of the MacOS understand *.img files. They also understand *.smi (self-mounting image) files. The *.dmg format is exclusive to MacOS X.

    .dmg = disk image

    that may sound simple, but once you learn about disk images, it will be very helpful. it is like a compressed file that can hold applications, movies, etc
