What is a DMG File

A DMG file is an Apple disk image file used to distribute software and package other non-application files on macOS Big Sur and Mac OS X. When you double-click the .dmg file, a virtual drive will be mounted on your desktop. DMG files are widely used on macOS because they can be fully verified and easily compressed to a smaller size.

How to Install Apps from DMG Files on Mac

When you want to install a third-party application from the Internet, the first thing you should do is download its DMG file to your Mac. When finished, double-click the .dmg file you downloaded, drag the application to the Applications folder, wait a few seconds, and your application will be installed on your Mac.

Note: Some DMG files are encrypted, and you may be asked to enter a password before installing them.

Can You Delete DMG Files After Installation

The answer is yes. After installing an application, you can directly delete its DMG file unless you want to keep it for archival purposes or in case the installation is incomplete. In addition, developers will update the application regularly. If you're going to use its updated version, then the old DMG file is no longer useful to you.
