Installing software simply requires you to open the .dmg file and then drag the application to your Mac’s Application folder. That’s much easier than using an Install Wizard in Windows. However, some of Mac newbies have no idea how to mount .dmg files in macOS or for some reason the .dmg file cannot be opened. Now this page will show you three methods to open and mount .dmg files on macOS.


Originally, DMG files are the default Disk Image file for Mac. Hence, they can be opened only on Mac OS. Since there are no manual methods available to view the DMG Files in Windows, users can install external third-party software available online on Internet.

A file with the DMG file extension is an Apple Disk Image file, or sometimes called a Mac OS X Disk Image file, which is basically a digital reconstruction of a physical disc. For this reason, a DMG is often the file format used to store compressed software installers instead of having to use a physical disc.

Method 1: Open .dmg file with DiskImageMounter

DiskImageMounter is the utility that handles mounting disk images in Mac OS X. Normally you can mount a .dmg file on Mac by simply double-clicking it or right-clicking on it and selecting Open With > DiskImageMounter (default). However, some people report that .dmg files cannot be opened on Mac in this way. If that’s the case, move on to another method.

DMGs and Other Archives: Just Drag and Drop. Most macOS applications downloaded from outside the store come inside a DMG file. The DMG file type is primarily associated with Macintosh OS X by Apple Inc. On the Macintosh, these files are treated like a real disk. They can be created with Disk Copy, burnt to CD or mounted as a normal volume. If you have a.DMG file on a Windows PC it's likely you have a Macintosh file and you won't be able to use what is in it. The dmg file type is a replacement for the older IMG format used in Mac OS Classic and is not compatible with Mac OS 9 or earlier. Apple DMG format is one of the most used format to install new applications to the Mac OS X (macOS). In computing world, DMG or (Disk Image File) is a file extension that belongs to Mac OS X.

Step 2: Type cd ~/Desktop and press Enter key.

Step 3: Type hdiutil attach googlechrome.dmg and press Enter key. Replace googlechrome with your .dmg file name.

That’s it. After you execute the two command lines, the .dmg file will be mounted on your Mac.

Method 3: Mount .dmg file using iSumsoft Bitlocker Reader for Mac

If you cannot open .dmg files on your Mac using either of the first two methods, it’s a good idea to use a third-party utility like iSumsoft Bitlocker Reader for Mac. iSumsoft Bitlocker Reader for Mac is mainly to help unlock BitLocker-encrypted drive on Mac, but it also comes with the Attach feature that can attach disk image on Mac.
