DMG disk images can be opened using the Apple Disk Utility that is bundled with macOS on Apple computers. DMG files are Mac-specific and are not intended for use in Windows. However, Windows Daemon Tools may be able to mount virtual drives from some DMG image files. I'm trying to install xcode 6 but when I double tap dmg icon, the popup appears and it tells me 'The following disk image couln't be opened. Image not recognized.' Please, can you help me? None of you are right (except the person who mentioned Toast). It's super easy to mount a disk image but mounting it so it appears as physical CD-ROM or DVD-ROM media is a different thing. I'm trying to play Age of Empires 3 on the Mac but it requires seeing the physical media and not just a mounted disk image. OS X El Capitan suddenly can't open DMG files. And managed to open.dmg files by going into Disk UtilityFileOpen Disk Image. Once opened in Disk Utility, Double.

What is a DMG file?
A DMG file is a mountable disk image created in macOS. It contains raw block data typically compressed and sometimes encrypted. DMG files are commonly used for macOS software installers that are downloaded from the Internet, which mount a virtual disk on the desktop when opened.
The DMG format replaces the older .IMG file format used in Mac OS Classic. DMG disk images can be opened using the Apple Disk Utility that is bundled with macOS on Apple computers.
DMG files are Mac-specific and are not intended for use in Windows. However, Windows Daemon Tools may be able to mount virtual drives from some DMG image files. Other utilities may also be able to convert DMG files to a format that can be recognized by Windows.

Dmg Disk Image Not Recognized Download
From time to time I’ve downloaded Mac OS X Disk Image files only to have the system display a cryptic warning that it failed to mount because it was “Not Recognized”. It’s happened several times when I tried to download the Intel Mac version of the excellent free 3D package Blender and I wrote it off as corrupted files.

It happened again yesterday but this time today I bumped into this weblog posting by Unsanity that points at a server configuration issue as being the cause. Basically, the disk image is sent to Safari as a generic blob of data instead of being tagged as a disk image and Safari makes an (incorrect as it turns out) guess presumably based on the “bz” in the file name that the disk image was compressed using bzip2 after it was created and appends the extension .bz2 to the download when in fact the bz probably means the contents of the disk image use that compression method. OS X dutifully applied the bz2 decompression algorithm to the disk image data, strips off the extension and attempts to mount the resulting disk image which fails because it’s been thoroughly scrambled.
Now many compression methods include internal checks (looking for specific tags or verifying a checksum) to make sure you are applying them to bone fide compressed data but it appears bzip2 doesn’t, or at least the OS X archive helper doesn’t use them.
The proper fix is to let the provider of the file know about the problem, and point them at Unsanity’s post at http://www.unsanity.org/archives/macosx/mydmgisbwokenafter_download.php for details. The temporary workaround is to, when and only when you see the “not recognized” warning, remove the .bz2 extension from the original downloaded file leaving just the final .dmg then try opening file again in the Finder. If this was the cause of the problem the disk image will successfully verify and mount.

As to why only the Intel version of Blender had the problem, it turns out that the PowerPC version is served as a .zip with the correct MIME type rather than as a .dmg disk image.

Thanks to the guys at Unsanity for the heads up on this one.
