A DMG (Disk Image) file is a type of file used by macOS to distribute software, including the operating system itself. A DMG file is essentially a mountable disk image that contains the installation files for the operating system or software. When a user downloads a DMG file, they can mount it as a virtual disk, allowing them to access the contents of the file.

If you are attempting to install macOS Catalina on VMware or VirtualBox (on a Windows or Linux PC), you specifically need the .dmg or .iso image, as you cannot run the Mac App Store. mac os 10.15 dmg
