Why macOS Uses DMG FilesThe main reason macOS uses DMG files is to make sure the file downloaded properly and wasn’t tampered with. DMG files include something called a checksum, which basically verifies that the file is 100% intact. This is what you see when the file is opening:This little window first goes through a phase of verifying the file, and then once it’s sure the file is good, moves on to decompressing it. And that’s second reason why macOS uses DMG files: they’re a compressed format (like a ) that makes your download smaller. Saving your data usage on downloads is always a good thing.RELATED: So How Do I Use DMG Files?Well, luckily macOS does an excellent job of making everything easy. All you really need to do is double-click the DMG file to open it and mount it to your Mac.The DMG mounts in two places: on your desktop and in the Finder sidebar under your hard drive.

Cleaning UpWhen you’re done installing the app, you’ll be left with two copies of it, one in DMG form, and one in your Applications folder. The DMG one can go since you don’t need it anymore.First, eject the DMG by right-clicking it and selecting the “Eject” command, or by pressing the eject button next to the disk in finder. This unmounts the DMG file from your system.Next, delete the DMG file itself unless you have a reason for keeping it around. Can I Use DMG Files in Windows?There’s not much reason you’d want to use DMG files in Windows since they usually contain macOS apps and not Windows apps.

But, if you need to get one open, has support for extracting DMGs. If you want to convert the DMG to a different compressed format (like, which is much like the DMG file format for Windows), a tool like will get the job done.
