DMG files are disk image files commonly used on macOS to distribute software. They function similarly to virtual hard drives, allowing users to install applications by mounting them like a physical disk. Once mounted, they appear as a new drive on the desktop. Users can then drag the application from the DMG to the Applications folder to complete installation. To open a DMG file, simply double-click it. After installation, remember to eject the mounted image by right-clicking and selecting ‘Eject’ for safe removal.
