How to Find and Delete DMG Files on Mac [2 Ways]

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 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.

Can You Delete DMG Files After Installation?

The answer is yes. After installing an application, you can delete its DMG file directly, 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.
