How to Correctly Remove DMG Files From Your Mac

Think of some of your most loved Mac apps. Imagine what it would be like to not be able to download and use them. That would be your reality if it were not for DMG files.

These are files used by software developers to distribute their apps to Macs outside of the App Store. They’re technically known as Apple Disk Image files and sometimes referred to as Mac OS X Disk Image files.  

As with any other file type, DMG files should be deleted when they’re no longer needed. Why keep excessive and unnecessary files on your Mac when you’ve successfully installed your apps?

Deleting files from your Mac is easy—anyone can do it. However, doing this yourself can leave behind junk files that can hide on your Mac. That’s why it’s best to use an app uninstaller to get the job done. 

 

MacKeeper’s Smart Uninstaller not only uninstalls apps, but it also finds and removes hidden files from the nooks and crannies of your Mac.

1. Download MacKeeper and open the app on your Mac
2. Select Smart Uninstaller on the left of the screen
