Double-click the file that you downloaded in step 5 to place the Microsoft Office 2011 14.6.3 Update volume on your desktop, and then double-click the Microsoft Office 2011 14.6.3 Update volume to open it. This step might have been performed for you. Install the DMG's app. Locate the icon for the app you're trying to install (e.g., Firefox), then click and drag the icon onto the 'Applications' icon in the window. This will prompt the DMG file's app to begin installing; once it completes, you'll be able to find in in the Launchpad menu.

When you want to install a new app on a Mac, more often than not they will let you download a .dmg file. For a long time, I thought that dmg file is just a special install package, but when working on the post about hiding files on Mac I found out that it is not so simple and I decided to investigate more.

I want to install a dmg file on a remote server. All I have is an ssh access. Since a DMG is a disk image, I tried to mount it, but mount does not seem to recognize its format. File says my dmg file is a VAX COFF executable. Keep the DMG to install in multiple computers without downloading in each; Control when and how to install Catalina, independently of when I manage to download it. Where do I get the DMG? The usual downloads page of apple only shows Mojave, previous OS and the usual apps.

General Information

What DMG stands for?

DMG stands for Disk iMaGe. macOS uses them to package multiple files and folders in one container which can be downloaded over the internet. Think of DMG files as virtual disks, they can be mounted and unmounted like any other drive. They do not have auto-run capabilities.

How to open a DMG file?

To start working with a DMG file it needs to be mounted. To mount the disk image double click on the DMG file. Double click on DMG files invokes DiskImageMounter app which is associated with these files by default. Once the image is mounted a new icon will appear on the Desktop.

Another way to mount DMG files is opening them from the Disk Utility in LaunchPad.

If the image contains an app installer you can see its contents by right-clicking on the app icon and selecting “Show Package Contents”.

Are DMG files safe to install?

Since DMG file is a disk image its safety depends on its contents. DMG files are neither safe or unsafe, but they may contain viruses or malware inside. When downloading from the internet always make sure that the web site you are downloading is from a trusted developer.

Downloading a DMG file does not compromise Mac security. To understand this better imaging someone packaged a virus in a compressed file, etc. zip file. Viruses get installed only when the container gets executed.

Downloading viruses or malware over the internet on the computer or copying files from one folder to another does not make any harm.

For instance, if you want to download Flash Player or QuickBooks from the internet go to their original web sites: Adobe and Intuit. Do not download software from unknown web sites.

How to check DMG files for a virus?

If you don’t have an antivirus installed on your Mac, you can try the site called Virus Total. The site was developed by a Spanish company, but later it was acquired by Google. It is totally free.

When a file is uploaded to the Virus Total it runs a number of different antivirus applications and prints the results of the scanning.

For instance, when I was working on my article See How Easy Is To Format External Hard Drive For Mac And PC I was able to identify that Minitool DMG contained a malware.

Is there a fake Adobe Flash Player?

I’ve seen many forum posts about fake Flash Players that install malware on Macs. The way they get installed is the web site pops up a warning message “Adobe Flash Player on your computer is outdated” and they provide a link to an updated version or immediately download Flash Player DMG on your Mac.

When this happens, Force Quit the browser and then delete the DMG file from the Downloads folder.

Flash Player (or any other app) will not install if DMG is not mounted and the installer app is not started.

Where do DMG files go?

When downloading DMG files go to the current user Downloads folder by default. However, the browsers may have other folders configured as Downloads, so if the browser didn’t download in the default folder check the browser settings.

If you can’t find the file, learn how to find files here. Just search for files with dmg extension.

When user double clicks on the DMG file the drive mounts and can be accessed either on the Desktop or from a sidebar in the Finder. If the drive is not visible in the Finder go to Finder’s Preferences and enable External disks box under Locations in the Sidebar tab.

Working with DMG files

How to create a DMG file

How To Install Office Dmg File On Mac Windows 10

Anyone who has a Mac can create a DMG file using Disk Utility. With Disk Utility you have options to create a black image or an image from an existing folder. There is a number of things that can be configured for a blank disk image: size, file format, encryption method, partition type, and disk image format.

Let’s review some of the options:

Size: the maximum size of the disk image. Once the disk image is created its size can be changed with Resize option in the Disk Utility.

Format: Use the following rules when deciding which format type to choose:

  • If the image will be used both in Mac and Windows choose MS-DOS (FAT) format for images less than 32GB, or ExFAT for images larger than 32GB
  • If the macOS version is Sierra or earlier than choose Mac OS Extended
  • If the macOS version is High Sierra or later, e.g. Mojave, choose APFS.

There are case-sensitive and case-insensitive options for macOS images. The safest approach is to stick to case-insensitive; they are defaults in macOS. Additionally, some applications may fail when accessing case-sensitive images.

Encryption: 128-bit is recommended, but no encryption provides a faster image.

Partition: Select Single Partition – Guid Partition Map. It is used with Intel-based MacBooks. Apple Partition Map is used with older PowerPC Macs. Master Boot Record Partition Map is used for bootable Windows images.

Image format: If you are not DVD/CD master, then you have a choice between read/write disk image and sparse images. When image format is set read/write then the new image will claim the entire size on disk as soon as it is created.

Sparse images allow creating a small initial image which will expand up to a predefined size. For instance, you can create a 100 MB file and upload only 5MB initially. The size of the image will be 5MB until you add more files. Note, however, the file will not shrink if you delete files. Once expanded it does not contract.

The difference between the sparse image and sparse bundle image is that the former consists of one giant file and bundle consist of a bunch of smaller files. When choosing between two options go with sparse bundle image (the other option is for compatibility with older Mac versions).

It is possible to change either encryption or image format after the image was created. To change encryption or image format start Disk Utility. In the menu go to Images -> Convert. Select the image, change the settings and click Convert.

The Disk Utility will create a new image, it will not override the existing one. So before converting make sure that you have enough storage for both images.

Another way to create an image is from an existing folder. For instance, you may want to create a secret image to store personal files.

Installing apps with DMG files

Since DMG is a container for an app or its installer the process of installing can be one of two following scenarios:

  1. When DMG file is mounted then it may ask to move the app to the Applications folder. All you need is to drag and drop the icon to the Applications folder icon.
  2. If the file contains the app installer then double-clicking on the installer will start a wizard which will ask questions and eventually install the app in the Applications folder.
    Once the app is installed it is safe to delete the DMG file. In fact, it is recommended to delete unused DMG files to clean the space on Mac. First, unmount it by right-clicking and select Eject from the pop-up menu and then delete the image file.

Can’t delete DMG file?

If any file from DMG file is in use (open with another application) then macOS will not allow deleting the file. Close the application that uses the files from DMG. In case when it is not clear which application is using files from the image restarting Mac will unlock the files.

Additionally, make sure that the disk is unmounted before deleting its DMG file. Sometimes, macOS allows to delete the image file while disk is still mounted, but this is not a good practice.

Why developers use DMGs to install apps on Mac

There are multiple reasons for choosing this format to install the software. Among them are:

  1. DMG files can be signed. macOS has an option to install software from the App Store only or from the App Store and identified developers. If a developer is a well-known company, e.g. Microsoft, then it gives the user additional assurances that the software came from the developer they trust.
  2. DMG files cannot be tampered with. So if Microsoft has signed the Skype package it is safe to copy from another computer and install it.
  3. DMG can be branded with custom icons and background images.
  4. DMGs can be encrypted.

DMG on Windows

Do DMG files work on Windows?

By default, Windows does not support DMG format. If you want to create an image which can be used between Mac and Windows, then install an application such as 7-zip to open DMG files on Windows.

Note however that 7-zip will only open the image as read-only, you will not be able to add new files or change existing ones.

But make sure that selected configuration for the image file is supported with 7-zip on the Windows you are running. I was able to open an image file with Mac OS Extended and MS-DOS FAT formats, but couldn’t open the one in ExFAT.

There are other options which can extract from DMGs in multiple formats. One of the DMG extractor from reincubate. It’s a paid app, but they do have a free version. Another app is a DMG viewer from Data Forensics which works also with corrupt DMG files.

One thing to remember is that macOS and Windows are different operating systems and applications written for macOS will not work in Windows and the opposite is also true.

So, if you were hoping to install a Mac app on Windows by opening a DMG file on Windows then I have to disappoint you – this won’t work. You can exchange files that are supported on both systems, e.g. .docx or .txt, but binaries are not compatible.

DMG conversion

DMG file to ISO

ISO is another virtual disk image usually used to make a copy of a DVD/CD. It also has to be mounted just like DMG. If you need to convert DMG to ISO format you will need a third-party application.

An example of such application is dmg2iso, it’s free, but it was not maintained for a long time. Another example is AnyToISO – a paid application from Crystal Idea.

Using with VirtualBox

Oracle VirtualBox is virtualization software. The beauty of VirtualBox is that you can run the entire computer inside another computer. For instance, if you need to run Windows on Mac one option is to run a VirtualBox and install Windows OS on VirtualBox instance.

VirtualBox supports DMG formats as one of the external devices. In order to use DMG with VirtualBox add the image as a virtual optical drive. The image cannot be used a hard drive because it cannot write into it.

Using with VMware

How To Install Office Dmg File On Mac Os

Currently, VMware does not support the DMG format. If you want to use the image with VMware you have to convert it first to ISO.

Conclusion

DMG is not a self-extracting archive which runs and installs software on Mac. It is, however, a container which includes the software to be installed. Disk images by themselves are not dangerous, but they might carry malware inside, so be careful when downloading them over the internet.

Disk images can also be used for personal use, e.g. when you need to package personal files in one container.
