.dmg is not an app, it is a disk image. If you double-click the file, it should mount a virtual disk in the Finder. From there, you will be able to drag and drop the image into your applications folder. A DMG file, which is also known as a DMG image is a mountable disk image created for the Mac OS X. It has the raw block data normally compressed and sometimes encrypted. DMG files are often used to install OS X software that is downloaded from the internet to mount a virtual disk on the Mac PC when opened.

Installing applications on macOS and OS X computers is easy to do when deploying the apps as packages through the Terminal using the Installer command for quiet deployments across your network.

– Click the Restore button
– Drag your dmg to your Source textbox

What is a disk image? Why not just zip?
Disk imagefiles are different than compressed files. Disk image is roughly a copy of the actual structure of disk. The OS will treat disk images just like a storage device, but a virtual one. For example, you can create a zip version of all files on a CD, but that zip file can't be used by the OS to boot the machine. With disk image file, it can. With disk image files, you can also create a image file of a CD, and that can be used to create a CD that is identical to the original CD.
Mac OS X's disk image file format is called “.dmg” files. For applications or executable files, it's better to use disk image format, because that way, all resource fork issues are done correctly, among other reasons.
