Create a DMG File on macOS: A Step‑by‑Step Guide

DMG, also known as disk image, is a file format used to organize and store files on your Mac, which can be regarded as a virtual disk drive. Each time you open a DMG file, it will automatically mount in the Locations section of Finder, like any mounted physical disk.

However, unlike the physical disk with a real form, you can create this virtual disk image file on a Mac with the built-in utility. The DMG file creation can be easier with two clicks as long as you run the right helper, iBoysoft MagicMenu. Let's see how to perform that mission!
