DMG is a native format for OSX. OSX will open DMG if you double click on it.
Apple's .dmg file format is used to deliver software or other files as a disk image. For a computer running Mac OS X you double click on the .dmg file and it will open and mount on the desktop as a disk. You can then either run the installer script or drag the contents from the mounted disk image onto the Mac's hard disc. Once you have finished with the contents of the disk image it can be ejected and deleted.
DMG is a file type. You don't install a DMG, you open it. Maybe there is something inside the DMG that can be installed, maybe not. It is a common way to send many kind of files. It is a bit like .sit or .rar.You can make your own DMG files and save things inside them, and send the dmg to your friends. Use Disk Utility to make DMG files. The DMG size is selectable and can be as big as your free memory. It will appear on the desktop. You can put a password on it, but don't forget it! If you do, you won't be able to open the DMG!To open the DMG you made, just click on it. A disk Image will appear on the desktop just like a hard drive.Drag or copy files there. Eject it. The DMG file is still on the desktop. It is a file that you can email or copy to an external drive. Everything that you put in the disk image will actually be in the DMG file. If you don't want the DMG any more, drag it to the trash.Cool!
.dmg (disk image files) can only be used under OS X. If you're running OS 9 or Windows, you won't be able to open this file. If you are running OS X, the file may be damaged.
.DMG is a compressed file used in MAC to mount a virtual drive, normally to install a program. To use this in Windows you will have to convert it to a similar file used in Windows like .ISO and use a mounting software to run it. However the files within the .dmg is probably for a MAC machine and might not work of Windows 7. Tag for further research: Apple Disk Image
Most downloaded software for Mac is distributed using disk image (.dmg) files. When a .dmg downloads, it will 'mount,' meaning that it makes its content accessible via the Finder (the desktop) so that the user can either install or view the contents (just as if it were an actual disk). When the user is finished with the contents of the 'virtual disk,' it can then be 'ejected' and the .dmg file can be deleted. The same process occurs when an actual external drive (USB or Firewire HD, flash drive, or other media) is connected, although those devices actually mount, rather than virtually.

Yes, it is generally safe to delete DMG files after you have installed the applications they contain. DMG files are disk images used primarily on macOS to distribute software, and once the installation is complete, they are no longer needed. However, if you think you might want to reinstall the application later, you may want to keep the DMG file. Always ensure that you have a backup of important files before deleting anything.
dmg files are automatically verified when they're mounted.

A .dmg file is a Mac disc image Its is basically a file that is an image of a disk, it can be mounted like a disk. It is much like a .iso image file seen a lot, except it supports compression and encryption. It is actually so much like an .iso with these extra features that there exists software packages that easily convert them back and forth.
No.
A mountable file is a disk image file that can be attached or "mounted" to a computer's file system, allowing users to access its contents as if it were a physical disk. Common formats for mountable files include ISO, DMG, and IMG. When mounted, the operating system treats the file as a virtual drive, enabling the user to browse, open, and manipulate the files within it without needing to burn it to a physical medium. This is often used for software installations, backups, and virtual machines.
